News: Informations- och kommunikationsteknik related to Chalmers University of TechnologyThu, 16 Nov 2017 15:26:48 +0100 kronor programme for Swedish AI research<p><b>​The Knut and Alice Wallenberg Foundation has granted an additional billion Swedish kronor to extend the Wallenberg Autonomous Systems and Software Program (WASP), with a broad investment into artificial intelligence.</b></p>​ <br />The initiative in artificial intelligence will follow two pathways. The larger of these involves an investment into machine learning, deep learning and the next generation of AI. This has been termed “eXplainable AI” and involves asking the system how it reached a particular answer, whereby the system can justify its answers and use them in a general situation. The second pathway deals with increasing our understanding of the mathematical principles behind AI.<br /><br />Each of the two branches has resources to recruit 14 senior researchers and 40 research students, where the research students will become members of graduate schools and take specialist courses in relevant fields. The two new graduate schools will coordinate with the graduate school that has already been established within the framework of WASP, where just over 100 research students are currently studying. Both the senior researchers and the research students will be recruited at the universities that are participating in WASP, primarily Chalmers University of Technology, the Royal Institute of Technology, Linköping University and Lund University. Further Swedish universities, however, may also benefit from the research grant.<br /><br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Information%20and%20Communication%20Technology/News%20events/DavidSands_170x220px.jpg" class="chalmersPosition-FloatRight" alt="David Sands" style="margin:5px" />&quot;This expansion of WASP is a fantastic opportunity for Chalmers and Sweden to build on our existing strengths in AI, but also recruit and train the next generation of AI experts,&quot; says David Sands, Chalmers representative in the WASP Program Management Group.<br /><br /><br />The grant also provides SEK 70 million to reinforce computing infrastructure.<br /><br />“This is a unique investment, even in an international perspective. WASP will in this way obtain the resources needed to create the knowledge platform that Sweden requires if it is to continue to hold its position at the forefront of research and remain competitive,” says Mille Millnert, chair of the WASP board.<br /><br />With this extension, WASP will have a budget of SEK 3 billion between now and 2026. At least 250 research students will be educated, at least 75 of them being industry-based research students. This is a powerful investment with connections to many different parts within artificial intelligence, software development and principles of autonomy. The new grant will also enable the recruitment of 46 senior researchers, the construction of demonstrators (arenas in which the research and commercial worlds can meet in concrete projects), investment into computer infrastructure, guest researcher programmes, and international collaboration.<br /><br />For more information about WASP at Chalmers, contact:<br />David Sands, Professor of Information Security, <a href=""></a><br />Mats Viberg, First Vice President with responsibility for research, <a href=""><br /></a><br /><a href="">Read the full press release from Linköping University &gt;</a>Thu, 16 Nov 2017 11:00:00 +0100 of a Swedish quantum computer set to start<p><b>​A SEK 1 billion research initiative is setting Sweden on course to a global top position in quantum technology.

We also present research at Chalmers that uses reinforcement learning.</b></p>​ <br />A grand challenge for artificial intelligence is to develop an algorithm that learns complex concepts from a blank slate and with superhuman proficiency. To beat world-champion human players at the classic strategy game Go, Google DeepMInd developed a program AlphaGo, trained through a combination of supervised learning based on millions of human expert moves and reinforcement learning from self-play. This program defeated Go champion Lee Sedol in a tournament in March 2016.<br /><br />A new version of the AlphaGo computer program, called AlphaGo Zero, was able to teach itself to rapidly master Go, starting from a blank slate and without human input, as reported in <a href="" target="_blank">a new paper published in Nature on 19 October</a>. It learns solely from the games that it plays against itself, starting from random moves, with only the board and pieces as inputs and without human data. And defeated its predecessor by 100 games to 0 after training for only 36 h.<br /><br />AlphaGo Zero uses a single neural network, which is trained to predict the program’s own move selection and the winner of its games, improving with each iteration of self-play. As the program trained, it independently discovered some of the same game principles that took humans thousands of years to conceptualize and also developed novel strategies that provide new insights into this ancient game.The new program uses a single machine and 4 TPUs while the previous version of AlphaGo was trained over several months and required multiple machines and 48 TPUs (specialized chips for neural network training).<br /><br />We will discuss the main principles and new extensions of reinforcement used in this work and at the end we will  briefly discuss research at Chalmers that uses reinforcement learning in autonomous driving and natural language technology research. <br /><br /><br /><strong>The seminar was held on 10 November 2017</strong><br /><span>Speakers: Devdatt Dubhashi, Mikael Kågebäck and others, Department of Computer Science and Engineering, Chalmers<span style="display:inline-block"></span></span><br />Location: RunAn, Chalmers Student Union Building, Chalmersplatsen 1, Johanneberg<br /><br /><br /><strong>Media coverage:</strong><br />The research paper from DeepMind caused a lot of media attention, also in Swedish media. <br />Chalmers machine learning experts have commented in Swedish media (in Swedish).<br /><ul><li><a href="" target="_blank">Devdatt Dubhashi in Yle.</a></li> <li><a href=";artikel=6801347" target="_blank">Mikael Kågebäck in Vetenskapsradion i P1</a>, and in <a href=";artikel=6801896" target="_blank">P4 Göteborg</a>, also partly available <a href="" target="_blank">on Facebook</a>.  </li> <li><a href="" target="_blank">Mikael Kågebäck in SVT vetenskap.</a>  </li></ul>Mon, 23 Oct 2017 17:00:00 +0200 research opportunities for Chalmers researchers as ElectriCity grows<p><b>​ElectriCity, best known for the electric bus 55 in Gothenburg, is much more than just the bus.

The one who finds the smartest method to quickly verify a system becomes highly sought after. Carl-Johan Seger is one of those people.</b></p>​ <br />In 1995, Carl-Johan Seger received a phone call with an offer that would change the direction of his research career at the University of British Columbia. He had only a few days earlier taken up a professor's appointment with so-called tenure, a meriting position.<br />&quot;I started my new position in June 1995 and in September I resigned,&quot; says Carl-Johan Seger, laughing at the memory.<br /><br />The phone call came from the American semiconductor company Intel, who was in great need of his skills.<br />&quot;There was a crisis at Intel. They had just rolled out a new generation of Pentium processors when a serious error in the construction was discovered. The error had escaped Intel's very extensive verification procedures. The final bill landed somewhere in the neighbourhood of 475 million dollar&quot;, he says.<br /><br />The problem was that the traditional verification method did not allow testing of all conceivable values, it could simply not be done within the time frame, even though very extensive verification was carried out.<br /><br /><strong>Mathematical tools for verification</strong><br />Carl-Johan Seger's research is on formal methods, i.e., mathematical tools for analysis and verification of systems. Very useful for verifying hardware – in this case silicon circuits. The tools that Carl-Johan Seger worked with in his research could offer the solution to the precise problems that Intel suffered.<br /><br />&quot;With formal methods, we developed a verification tool that was not only more reliable, we could also perform the verification faster.&quot;<br /><br />As a result, Carl-Johan Seger introduced early formal verification in the development process at Intel. <br />&quot;Early formal verification is extremely important for achieving good results. It is only after we verify that we can know for sure, and can draw conclusions from the work. It is usually said that we learn by our mistakes, and I couldn’t agree more.&quot;<br /><br />At Intel, he created the Forte Formal Verification System, based on his previous research, and the same verification system is still used today, over 20 years later.<br />&quot;If you buy a computer today with an Intel processor, large parts of the processor are verified by this method.&quot;<br /><br /><strong>Return to academia</strong><br />He stayed at Intel for 22 years, and during that time he has published his research with great impact.<br />&quot;It has been fun working in industry, but there is not much long-term research done. In 2006-2007, I was given the opportunity to be a visiting researcher at Oxford&quot;, he says. <br /><br />Perhaps that is where the thoughts of returning to academia took shape? So, when Intel last year announced staff cuts, and launched a retirement package, he took the offer.<br />&quot;Intel's offer turned to those who with x number of years in the company, added with one's own age, summed to the number 75 or higher. And it included me with a 3-month margin.&quot;<br /><br />Carl-Johan Seger is pleased with his choice to return to academia and Chalmers, and the mood is on top during the interview. We wonder, of course, how he experiences the transition.<br />&quot;It's a big change, I cannot say it's neither better nor worse, but on the other hand – it takes a lot of effort and renewal and it makes me feel younger.&quot;<br /><br /><strong>Important part of autonomous systems</strong><br />Carl-Johan Seger is recruited as part of Chalmers activities in the Wallenberg project WASP – <a href="/en/areas-of-advance/ict/research/automated-society/wasp/Pages/default.aspx">Wallenberg Autonomous Systems and Software Program</a>. An important trend along with the development of autonomous systems is the decreasing gaps between hardware and software, we are seeing much more of programmable hardware. There are two very big benefits to doing so – increased performance and reduced energy consumption.<br /><br />&quot;When a large number of sensors are introduced to enable an autonomous system, and all sensors are sending their data to a central processor, it becomes inefficient and slow. Through programmable hardware, or FPGA, Field-Programmable Gate Array, we can introduce more intelligence closer to the sensors&quot;, says Carl-Johan Seger.<br /><br />FPGA are circuits in which the function of the circuit is determined by software. It provides flexibility, you do not necessarily need to re-design your hardware to introduce new functionality – just rolling out new instructions is enough. But there's a big challenge, it gets a lot more difficult to design and verify.<br />&quot;Look at cars for example, they contain many computer-powered features, and it's crucial that the systems respond quickly, never fail and are secured. This is what we are testing using formal methods&quot;, says Carl-Johan Seger. <br /><br />So, what does Carl-Johan Seger think about the future of self-driving vehicles out of a safety perspective? He says that there are several layers of technology in the vehicles – all are not critical systems.<br />&quot;There is a core in the systems that we need to find solutions for, in order for the self-driving vehicles to succeed. The future is about robust technology, but it's also about working out the regulations and what the consequences are if anything goes wrong. The market will determine how big risks that are reasonable to take. If the cost of errors becomes too large then we will not see any self-driving vehicles on the roads.&quot;<br /><br />Carl-Johan Seger points out that autonomous systems are not just about vehicles. We will see all sorts of new services, inspections, deliveries, window cleaning, and a host of applications in industry.<br />&quot;The development of autonomous systems leads to an increasing need to do right from the start – and thus it gets more and more important with verification. It is simply faster and less of a business risk to do it right the first time.&quot;<br /><br /><strong>Back at Chalmers</strong><br />Carl-Johan Seger is now recruited to Chalmers as Professor of Computer Science. Which means he is back at Chalmers where he started his studies in 1981, after nearly 34 years in Canada, the United States and Britain.<br />&quot;I don’t say I'm moving <em>back </em>to Sweden. I've been away for so long, so I say I'm moving to Sweden. It actually makes it a little easier for me.&quot;<br /><br />The first task at Chalmers is to build a verification system. Intel has proprietary ownership of the Forte system, so Carl-Johan Seger could not bring it to Chalmers for further research.<br />&quot;My wife usually says Forte is my fourth child, and maybe there is something to it. I have spent at least as many hours with Forte as with my three children.&quot;<br /><br />However, he has the old system to build on, the one he developed during his time as a researcher before leaving for Intel.<br />&quot;Now we are rebuilding, and this time, of course, it will go much faster because we already know the target.&quot;<br /><br /><br />Contact details: Carl-Johan Seger, <a href=""></a><br /><br /><em>Text: Malin Ulfvarson</em><br /><em>Photo: Anneli Andersson</em>Tue, 17 Oct 2017 09:00:00 +0200 Centre Day for ChaseOn and GigaHertz Centre<p><b>​On 14 November, Chalmers excellence centres ChaseOn and GigaHertz Centre will arrange their joint day in Palmstedtsalen.

The United-Grid project aims to secure and optimize operation of the future intelligent distribution networks needed to handle the increasing complexity.<br /><br />The EU Horizon2020 project runs from November 2017 to April 2021 and the consortium consists of eleven partners from France, The Netherlands, and Sweden. The research team from Chalmers is cross-disciplinary and include Tuan Le, David Steen from the department of Electrical Engineering, and Magnus Almgren, Marina Papatriantafilou, Vincenzo Massimiliano Gulisano from the department of Computer Science and Engineering.<br /><br />The core deliverable is the United-Grid tool-box that could be “plugged in” to the existing Distribution Management System (DMS) via a cross-platform for energy management, grid-level control and protection. The Computer Science and Engineering work in the project is about security perspectives in the distributed infrastructure, in which the data-stream processing methods are catalytic for addressing detection possibilities.<br /><br />United-Grid was prepared in response to the Horizon2020 work program “LCE-01-2016-2017: Next generation innovative technologies enabling smart grids, storage and energy system integration with increasing share of renewables: distribution network”. <br /><br />Contact: <br />Project coordinator, <a href="/en/Staff/Pages/anh-tuan-le.aspx">Tuan Le</a>, Electrical Power Engineering, department of Electrical Engineering<br />Project administrator, <a href="/en/staff/Pages/jacqueline-plette.aspx">Jacqueline Plette</a>, Chalmers Operative and Strategic Support<br />Thu, 28 Sep 2017 09:00:00 +0200 is becoming a unique marketplace for energy<p><b>​Campus Johanneberg is becoming a test arena for the local energy supply of the future.

Chalmers is part of a two-year project that brings together industry and academia to develop a common global standard for future vehicle communication.</b></p>​“It's about using telecommunications to increase traffic safety and transport efficiency through connected and collaborative systems”, says Professor Erik Ström, Head of Communication and Antenna Systems at the Department of Electrical Engineering. “Today's wireless mobile system is not powerful enough to be used for vehicle communication, where safety always must be put first.”<br /><br />For traffic safety applications, very high demands are imposed on the reliability of the data being transmitted. In some cases, more than 99.999 percent of the transmitted information must also be delivered to the recipient.<br /><br />“In addition to the demands of high reliability, it is also crucial that data communication is fast and not delayed”, he continues. “In order to be traffic-safe, transmission times have to be as short as 5 milliseconds in certain use cases. This is very challenging.”<img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Projektet%20som%20sätter%20standarden%20för%205G%20i%20fordon/Erik_Strom_200x280px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><br /><br /><strong>Creates consensus among competitors</strong><br />In the project, competitors like Ericsson, Nokia and Huawei side by side, along with vehicle manufacturers like Volvo Cars and PSA, work out the common prerequisites for the 5G system and a global standard for vehicle communication.<br /><br />The work is about creating consensus and to agree on matters that need to be standardized. The telecom industry requires a common system platform to start from, when the manufacturers in the next step separately develop their products for the market.<br /><br />&quot;I am very pleased that we at Chalmers are taking part in setting the standard”, says Erik Ström. “It is an important and highly sought-after network to participate in, including both industry and other universities. We contribute, among other things, with knowledge from our fundamental research on positioning and wireless systems. In total, we expect the project to involve 46 month´s work for our researchers.”<br /><br />A part of the project is about vulnerable road users, such as pedestrians and cyclists. When the 5G technology is available in each person's mobile phone, data collection for example about position, direction and speed could be used to further enhance traffic safety in different situations.<br /><br />The project started in June 2017, and Chalmers made the first part-delivery in early September. By mid-2019, selected technology components will be demonstrated and project results incorporated into the 5G standard. The overall goal of 5GCAR is that vehicles connected with 5G technology will be out on the roads from 2020.<br /><br /><strong>Renewed confidence</strong><br />&quot;We are very pleased to, once more, been given the confidence to use our research in the development of technology that enables 5G in vehicles&quot;, says Erik Ström. “For us, this is the second project within 5GPPP.

She is being interviewed in the new issue, in which her latest scientific paper – co-written with colleagues at Chalmers and Hewlett Packard Enterprise in the U.S – is published as well.<br /><br /><img src="/SiteCollectionImages/Institutioner/MC2/News/vcsel_array_350px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />Ewa Simpanen's research is about increasing the wavelength for low-cost laser and fiber technology to meet the growing needs of optical interconnects in the massive data centres – operated by giant service providers like Facebook and Google – that underpin our Internet-enabled world. <br />“The purpose of this work is to develop high-speed, longer wavelength those while still using the GaAs-based material systems as it enables the fabrication of VCSELs which are superior to those based on other material systems in terms of speed, efficiency, manufacturability, and cost”, says Ewa Simpanen.<br /><br />In the June issue of Electronics Letters she and her colleagues present a VCSEL design operating at 1060 nanometer, equal to one millionth of a metre.<br />“We have limited the wavelength extension to 1060 nm since the long-term reliability of GaAs-based VCSELs may be compromised if extending the wavelength beyond ∼1100 nm”. It is a longer wavelength than the current GaAs standards, located at 850 and 980 nm, to reduce chromatic dispersion and attenuation in the fiber, which is crucial for reaching the longer ranges of data centers. We have tried to find a sweet spot with the wavelength in between, explains Ewa Simpanen for Electronics Letters.<br /><br />VCSEL means vertical-cavity surface-emitting laser.<br /><br />Text and photo: Michael Nystås<br /><br />Caption: <br />A microscope image of an array of VCSEL devices on chip; newly fabricated and ready for characterisation.<br /><br /><a href="">Read the article in Electronics Letters</a> &gt;&gt;&gt;<br /><br />Source: Electronics Letters, Volume 53, Issue 13, 22 June 2017, page 819<br />DOI:  10.1049/el.2017.2117 , Print ISSN 0013-5194, Online ISSN 1350-911X<br />Tue, 08 Aug 2017 09:00:00 +0200, sustainable data processing with hyper effective memory compression<p><b>​A new technology for memory compression developed at Chalmers has proved capable of saving up to two thirds of memory and bandwidth with retained performance. The technology is now finding its way to the market through ZeroPoint Technologies AB,  a startup company founded by professor Per Stenström and his former PhD student Angelos Arelakis.</b></p><img src="/SiteCollectionImages/Institutioner/DoIT/News/Angelos.jpg" class="chalmersPosition-FloatRight" alt="Angelos Arelakis" style="margin:5px" />When Angelos Arelakis began his doctoral studies with Per Stenström at Chalmers in 2010, they sat down to discuss possible topics for the dissertation, and the potential of memory compression came up. Per Stenström suggested &quot;a simple experiment to get things on the road&quot;, and the results of those tests were far beyond all expectations. The research that has followed has now evolved into a promising business concept. <br /><br />Usually the subject of memory compression is about compressing data to be stored or transported without processing. In modern computers arithmetic operations are performed in the CPU, which means that data must be fetched from memory when calculations are to be made, traffic that costs both time and energy. The new technology developed at Chalmers handles active data, while it's being processed. <br /><br />&quot;The benefit of the technology is increased memory capacity, but also increased CPU and memory throughput, which basically will lead to improved performance without affecting the physical size of the memory, or the energy consumption,&quot; says Angelos Arelakis. <br /><br />He left Chalmers earlier this year to become chief system architect at ZeroPoint Technologies AB, the company he founded with Per Stenström in 2015, with the goal of commercializing the technology he developed as a PhD student. The company aims to release its first product on the market in 2017, and as the technology can be applied to all types of data, the potential customers are companies that deal with everything from smartphones to major computer centers. Already in the early research results, Per Stenström anticipated future commercial opportunities, and the first patent application was filed in 2012. Since then, six more applications have been submitted, and the first patent has been granted. <br /><br />Solutions that improve storage capacity through different compression systems and methods are already on the market, some are even fast enough to also provide improved memory capacity. What's unique with the technology from Zeropoint is the combination of speed, intelligent compression and generality. Because the compression algorithms are implemented in hardware logic rather than in the software, they become extremely fast, and the software developers can continue as usual without the need for any adjustments. The company has evaluated various applications in collaboration with several international IT companies. <br /><br />&quot;There is no golden business model, you need to do trial and error. We have taken different applications to some potential customers, and they need to verify that the technology works. If it doesn't make sense, it's not meaningful to proceed. The product we are closest to launching now is a licensed IP core,&quot; says Angelos Arelakis. <br /><br />ZeroPoint Technologies AB has received start-up contributions from, among others, Chalmers Ventures and Qamcom, to take the product to the market. Angelos Arelakis has also been awarded a scholarship from <em>King Carl XVI Gustaf's 50th birthday foundation for science, technology and the environment</em> to further develop his research. The company currently employs about 8 people, but recruits continuously for new positions.

In this project, he has collaborated with Peter Sobis, guest researcher at TML and R&amp;D Adviser at Omnisys Instruments, one of Sweden's leading space companies with close connections to Chalmers. In close collaboration with Omnisys, TML has increased the technical maturity of Chalmers Schottky diodes to meet requirements for space applications.</div> <div> </div> <div>&quot;We have created a well-functioning collaboration platform that can efficiently build on ideas and knowledge in a research environment like that at Chalmers, to develop and create competitive products in Swedish industry, including for the commercial space market,&quot; says Peter Sobis in a brief comment.</div> <div> </div> <div>We got the opportunity to ask Vladimir Drakinskiy a few questions about the project and the efforts of him and Peter Sobis.</div> <div> </div> <h5 class="chalmersElement-H5">Could you tell me a bit about the recent activities?</h5> <div>&quot;The recent activities have involved audits and reviews conducted by ESA and Airbus, which we also collaborate with in the project. This has included the Chalmers Schottky process line at the Nanofabrication Laboratory and the delivery of space qualified components to Omnisys Instruments in the frame of the MetOp SG program&quot;, says Vladimir.</div> <div> </div> <h5 class="chalmersElement-H5">What's a Schottky diode?</h5> <div>&quot;A Schottky diode is a very fast two terminal electronic device consisting of a semiconductor to metal interface. The semiconductor in this case is a doped GaAs material with a Titanium-Platinum-Gold metal interface on top. The device can be used for generating and detecting microwave and terahertz radiation. In this case, to characterise various oxygen and water lines, a part of the terahertz frequency spectrum.&quot;</div> <div> </div> <h5 class="chalmersElement-H5">What's the background to all this?</h5> <div>&quot;MetOp SG stands for second generation Metrology Operation and is a second-generation weather and climate research satellite program that was commissioned in 2014, and that will provide weather and atmospheric data to the European countries. Operator is the European Telecommunications Satellite Organization (EUTELSAT).&quot;</div> <div> </div> <h5 class="chalmersElement-H5">Why is this so important?</h5> <div>&quot;MetOp SG is one of the biggest ESA programs and will be used not only for more precise weather forecasting but also for continuous long term atmospheric monitoring, which is crucial for better understanding of the underlying effects of global warming and long term prognosis of earth's climate.&quot;</div> <div> </div> <h5 class="chalmersElement-H5">Could you describe your own roles in the project?</h5> <div>&quot;Chalmers has developed a world class semiconductor process for terahertz Schottky diodes with unique qualities required for space applications. My role was to develop the fabrication technology to meet the formal requirements set by ESA and Airbus. Omnisys provided specifications, circuit demonstrators and carried out most of the reliability tests.&quot;</div> <div> </div> <h5 class="chalmersElement-H5">Has it been a time-consuming project? For how long have you been working with it?</h5> <div>&quot;The project has been part of a larger ongoing effort of developing a state-of–the-art semiconductor process specialised for terahertz space applications at Chalmers. For MetOp, a prequalification phase was initiated by the same team almost five years ago which later lead to a contract for fabrication and delivery of flight components which is where we are now.&quot;</div> <div> </div> <h5 class="chalmersElement-H5">I heard you celebrated with cake. How did this attention feel for you?</h5> <div>&quot;It has been a lot of hard work and it feels great to finally have succeeded. We are very proud of our achievement and already see the effects in upcoming projects with ESA&quot;, says Vladimir Drakinskiy.</div> <div> </div> <h5 class="chalmersElement-H5">What's happening now? What's the next step?</h5> <div>&quot;We have several projects running and will also soon initiate a new ESA project aiming for space qualification of our Schottky and HBV devices at even higher frequencies.&quot;</div> <div> </div> <div>Jan Stake is professor in terahertz electronics and head of the Terahertz Millimetre Wave Laboratory (TML) at MC2, where the project has been conducted. He is very pleased with the results:</div> <div>&quot;Delivering unique technology to one such project is of course a huge achievement of Chalmers. The project has been very challenging, different, but a great learning experience and raised the overall quality and ability related to process and manufacturing of terahertz electronics in the Nanofabrication Laboratory at Chalmers. Vladimir and Peter, clean room staff and everyone involved, have done a great work&quot;, he comments.<br /><br />Peter Modh is head of the Nanofabrication Laboratory:<br />&quot;The project shows that even in a lab that is not really certified, it is possible to get very advanced components that's strong enough to send out in space. It is a strength&quot;, he says.</div> <div> </div> <div>Text: Michael Nystås</div> <div>Photo: Anna-Lena Lundqvist </div> <div>Photo of satellite: ESA – Pierre Carril</div> <div> </div> <h4 class="chalmersElement-H4">METOP FACTS</h4> <div>MetOp is short for The Meteorological Operational satellite programme. It is a European undertaking providing weather data services to monitor the climate and improve weather forecasts. It represents the European contribution to a new co-operative venture with the United States National Oceanic and Atmospheric Administration (NOAA).</div> <div> </div> <div>MetOp is a series of three satellites, forming the space segment of Eumesat's Polar System (EPS). Launched on 19 October 2006, MetOp-A, the first satellite in the series, replaced one of two satellite services operated by NOAA and is Europe’s first polar-orbiting satellite dedicated to operational meteorology. </div> <div> </div> <div>MetOp-B, the second in the series, was launched on 17 September 2012 and operates in tandem with MetOp-A, increasing the wealth of data even further. The third and final satellite, MetOp-C will be launched in 2018. </div> <div> </div> <div>Launching a new satellite every 5–6 years guarantees a continuous delivery of high-quality data for medium- and long-term weather forecasting and climate monitoring until at least 2020. </div> <div> </div> <div><a href="">Read more about the MetOp project</a> &gt;&gt;&gt;</div> <div> </div> <div><a href="">Read more about Schottky diodes</a> &gt;&gt;&gt;</div> <div> </div>Fri, 30 Jun 2017 10:00:00 +0200
