RADIOBLOCKS: A New European Consortium to develop Next Generation Technologies for Radio Astronomy Infrastructures

February 2, 2023

The RADIOBLOCKS project, coordinated by JIVE ERIC and including major European research infrastructures for radio astronomy, together with partners from industry and academia, have been granted 10 M€ by the European Commission to develop “common building blocks” for technological solutions beyond state-of-the-art, that will enable a broad range of new science and enhance European scientific competitiveness. The RADIOBLOCKS project will start on 1 March 2023.

 

The RADIOBLOCKS project will take a holistic view of how radio telescopes arrays capture, process, synthesise and analyse cosmic signals and will develop components, technologies and software, applicable to a wide range of instruments, to enable the next major discoveries in radio astronomy.

 

RADIOBLOCKS aims to achieve a maximal boost for the major world-leading research infrastructures in radio astronomy by developing common needed blocks:

 

●  for the development of new correlators, which can efficiently exploit powerful new commercially available accelerator hardware (GPUs). This development will directly benefit the large radio arrays from meter to sub-mm wavelengths;

●  in cutting-edge frontend technologies, addressing the generation and real-time handling of wide band and multi-band data, in particular for the creation of novel detectors and components, both RF and IF, as well as the design of backends, with built-in RFI mitigation;

●  for multipixel (PAF/FPA) receivers, ranging from cm to submm wavelengths, suitable for large single dish facilities, with special relevance for future collaborations with pan-European and global RIs (e.g., SKA-VLBI).

●  for data (post)processing, testing prototype workflows functionality and demonstrating usage of end-to-end simulation tools.

 

"The project RADIOBLOCKS collects the experience and common interests of the radio astronomy community in Europe at large, including several other global parties and industry. For the first time, all will work together to develop the technologies that are necessary for the future evolution of their facilities. This is a paradigm shift, mostly facilitated by the European Commission's Horizon Europe programme", says Dr. Francisco Colomer, director of JIV-ERIC and coordinator of RADIOBLOCKS.

 

The 4-year RADIOBLOCKS project - funded by the Horizon Europe Framework Programme -

involves 33 major European research infrastructures for radio astronomy, together with partners from industry and academia from 9 European countries, Japan, Republic of Korea, South Africa, and the United Kingdom. The engagement with industry to co-develop advanced technologies will increase the partners’ technological levels and strengthen their market positions.

 

The European research infrastructures (RI’s) involved in RADIOBLOCKS are the Joint Institute for VLBI ERIC (JIV-ERIC) and the European VLBI Network (EVN), the Multi Element Remotely Linked Interferometer Network (eMERLIN), the LOw Frequency ARray (LOFAR/ILT, in the process to become LOFAR ERIC), the Northern Extended Millimetre Array (NOEMA), the 100-metre Effelsberg Telescope, the Sardinia 64-m radio telescope, the Yebes 40-metre telescope, the IRAM 30-metre Telescope and also global facilities of European interest, such as the Square Kilometre Array Observatory (SKAO, an ESFRI landmark), the Atacama Large Millimetre Array (ALMA), the Global Millimetre VLBI Array (GMVA), and the Event Horizon Telescope project (EHT).

 

“The RADIOBLOCKS project brings together world-leading academic research and industry experts from across Europe and beyond to co-develop and then exploit new technologies to maximise the science capabilities of current and future radio facilities,” says Prof. Rob Beswick, Head of Science Operations and User Support for e-MERLIN, the UK’s National Radio Astronomy Facility; Deputy Director of the UK SKA Regional Centre and RADIOBLOCKS lead at The University of Manchester.

 

The project builds on the highly consolidated RadioNet consortium, which, since the year 2000, have been supported by the European Commission through their different Framework Programmes. RadioNet has successfully integrated a unique array of capabilities and contributed to the continued advances in radio astronomy, which are recognised as essential in answering key questions in astrophysics.

 

The RADIOBLOCKS project is coordinated by JIV-ERIC, showing its central role as a coordinating research infrastructure bringing together the major research organisation in the radio astronomy field and its expertise coordinating several EC-funded projects in recent years such as the H2020 JUMPING JIVE.

 

For JIVE ERIC and the EVN, RADIOBLOCKS will have a major impact for the development of a next generation Very Long Baseline Interferometry (VLBI) Correlator. The EVN technology roadmap for 2020-2030 highlighted the need for broad-band developments, extending the observing bandwidth by at least to 5 GHz, which also requires recording the data at a rate of up to 32 Gbps, an observing mode that will be fully compatible with the Square Kilometre Array (SKA-MID). Bringing in the SKA-MID, and several other telescopes is the other way to increase the sensitivity of VLBI observations performed by the EVN. This is particularly important for narrow-band phenomena - like Fast Radio Bursts (FRBs) - where the only way of improving the sensitivity and imaging capabilities is increasing the collecting area (i.e., the number of telescopes, distributed evenly on various angular scales). To be able to process these broad-band data for large number of telescopes (>30), a next generation VLBI correlator, including specific modes optimised for processing large fields of view, short transients (microseconds time scale), and high spectral resolution modes, is necessary.

 

During the RADIOBLOCKS project, the VIRAC team will contribute to the development of a software that will be used for data processing in several VLBI networks (EVN (European VLBI Network), ILT (International LOFAR Telescope), ALMA (Atacama Large Millimeter Array), SKA (Square Kilometre Array), EHT (Event Horizon Telescope)) and will be useful for the whole radio astronomy community. It should be underlined that during the project, the data processing algorithms previously developed by the VIRAC team will be improved and applied to the observational data of the EVN and ILT networks. These algorithms are based on the KLT (Karhunen-Loève transform) and SSA (Singular Spectrum Analysis) methodologies. The results of the project will be used for further development of a single-base interferometer using the RT32 - RT16 interferometer in the Irbene radio telescope complex, and the results will allow the development of LOFAR VLBI capabilities.


“RADIOBLOCKS is an ambitious project that will bring together 33 partners from industry and academia from all over the world.” says Dr. Giuseppe Cimò, head of Space and Innovative Applications at JIVE and Project Manager of the RADIOBLOCKS project. “It will be an exciting challenge to help develop the common blocks that European Research Infrastructures will use to create exciting scientific results to answer key questions in astronomy and astrophysics.”

The RADIOBLOCKS project will receive funding from the European Union’s Horizon Europe research and innovation programme under grant agreement No 101093934.

Translation Students Visit the European Parliament in Brussels

By Rota Rulle • October 6, 2025
At 7 AM on the 24th September an airplane took off to fly to Brussels. It was a quiet morning, the air was charged with excitement and sleep deprivation, when seven 4TLT students, along with lecturer Zane France arrived at their destination, where they were welcomed by European Parliament’s vice-presidents’ assistant Guna Zaķe-Baltā. VUAS students had the opportunity to get lost in the ‘labyrinth’ of the European Parliament, attend a lecture about the work of both the European Parliament and its members, as well as get a glimpse into the history of the establishment. The students could learn about how actively (or not) Latvia participates in voting, how much ‘pocket money’ do members get, what is the monthly schedule and how often do the meetings happen in Brussels and Strasbourg. After the lecture the excursion continued, and the students saw a part of the enormous building of the Parliament (one can wonder, do the new hires get a compass and a map?), the famous conference room, gifts of the countries of the European Union (including artworks gifted by Latvia), and even the cabinet of Roberts Zīle (where the guests were greeted by sandwiches, apples, and chocolate :) ). The cherry on top was the opportunity to meet with the European Parliament’s interpreters Dace Rubene and Ilze Lauva, and the Head of the Latvian unit of Directorate-General of the European Commission Uldis Sproģis and talk about how many languages interpreters usually know, how does interpreting differ in the European Commission and European Parliament, what is retour, and what should one do if the speaker’s tempo is too fast, as well as if voice matters in interpreting. At the end, the students had the opportunity to try interpreting in the Conference Interpretation Booths (with the microphone, hopefully, turned off!) and interpret the conference about the safety of minors on the internet. It was a wonderful experience that allowed the students to learn about the professionalism of the interpreters and working in the Parliament, as well as internship opportunities and how difficult it is to become an interpreter in the European Parliament. In the evening and on the next day, the students were given free rein to taste Belgian chocolate, see the Peeing boy statue and ponder on whether to come back and work in the Parliament. Impressions of the participants: “Although I have never thought that conference interpreting is easy, this tour highlighted how difficult and challenging it actually is and what enormous wealth of background knowledge interpreters need to have.” “I really enjoyed the trip! At first, I wasn't too sure whether to participate, but I’m happy that I mustered up my courage and decided to go. I can definitely say that visiting the European Parliament is a wonderful opportunity, and that it was very interesting to learn about the work and experiences of the interpreters.” “I will definitely remember the visit to the European Parliament for an eternity, but the meeting with the interpreters that work there is what left the most significant impression. For a while I thought that they’re some kind of superheroes – which they definitely are – but after the meeting I realised that they are people just like us. Thanks to them, work in the European Parliament has turned from something intangible into a real possibility you can achieve by investing a lot of hard work.”

COLOURS alliance’s greeting on the European Day of Languages

By Rota Rulle • September 26, 2025
Approximately 700 million Europeans are constantly encouraged throughout their lives to learn as many languages as possible – whether in educational institutions, through self-study, for professional purposes, or out of personal interest. The Council of Europe states that multilingualism is a means to foster better intercultural understanding and is a key component of our continent’s cultural heritage. Representatives from the language centres of the COLOURS European Universities Alliance* joined forces in a collaborative project, creating a video greeting in honour of the European Day of Languages, celebrated annually on September 26. Ventspils University of Applied Sciences is represented in this team by Rūta Maltisova, lecturer at the Faculty of Translation Studies, who also took part in the creation of the video greeting. Rūta is currently working together with colleagues from all COLOURS partner universities on a virtual language and culture guide – a glossary and language learning materials – which are planned to be developed and made available to all partner universities by the European Day of Languages in 2026. This initiative aims to support students and lecturers in learning and teaching nine European languages and cultures: Swedish, Spanish, French, Italian, German, Latvian, Polish, Croatian, and Macedonian. At the end of the video, greetings can be heard in each of the COLOURS alliance member languages, all translating into English as “Happy European Day of Languages!” or in Latvian, “Priecīgu Eiropas valodu dienu!” On the European Day of Languages, Rūta Maltisova encourages everyone to remember that languages are like bridges connecting different cultures. Without them, we would only be able to observe each other from a safe distance, separated by a potential barrier of prejudice that prevents us from understanding the essence and values of another culture. By learning a language, we also learn about the culture – and, in doing so, we learn about one another. Thanks to the COLOURS Universities Alliance, we learn something new every day about each other’s cultures, values, and, undoubtedly, languages. *Le Mans University (France), University of Castilla-La Mancha (Spain), University of Ferrara (Italy), Paderborn University (Germany), Jan Dlugosz University (Poland), Josip Juraj Strossmayer University of Osijek (Croatia), University St Kliment Ohridski Bitola (North Macedonia), Kristianstad University (Sweden), and Ventspils University of Applied Sciences (Latvia).

The visit began with a trip to the VIRAC radio telescope complex in Irbene, where senior researcher Artis Aberfelds introduced the guests to the telescopes, associated equipment, and laboratories, and their use in astronomical observations. After a joint lunch at VUAS café Panorāma, Jānis Šate showed the guests the university's electronics teaching laboratories and their equipment. The event reached a productive apogee in a joint discussion lasting around two hours in the VUAS Rectorate conference hall. At its opening, Rector Andris Vaivads gave a presentation about VUAS, followed by a presentation by, Juris Kalvāns, Head of the VIRAC Astronomy and Astrophysics Department, about the main research directions in VIRAC astronomy, while researcher Vladislavs Bezrukovs outlined VIRAC's extensive international cooperation, particularly its participation in European Research Infrastructure Consortia (ERIC). “The event reached a productive apogee in a joint discussion lasting around two hours in the VUAS Rectorate conference hall, where Rector Andris Vaivads gave a presentation about VUAS.” The discussion covered a range of topics related to science and studies. Both sides expressed interest in officially involving VUAS in the UL Master’s programme in Physics, alongside Daugavpils University. VIRAC researchers already teach several astronomy courses within this programme. The potential involvement of the VIRAC high-performance computing cluster in a new computing consortium, where UL is expected to take the leading role, was also discussed. Looking further ahead, UL is also interested in gaining access to VIRAC satellite communication abilities. Finally, the UL–VUAS cooperation agreement is to be renewed, including matters of collaboration in doctoral studies and research, as well as Latvia’s participation in the International Astronomical Union. The meeting took place in a frendly atmosphere, giving confidence in the successful continuation of cooperation between UL and VUAS.
