European Union-funded project “Opticon RadioNet Pilot” concludes at Ventspils International Radio Astronomy Center (VIRAC)

April 16, 2025

In February of this year, the European Union-funded project “Opticon RadioNet Pilot” No 101004719 (ORP) was successfully concluded at the Ventspils International Radio Astronomy Center (VIRAC), part of Ventspils University of Applied Sciences, located in Irbene, Latvia.


VIRAC is known for its two large radio telescopes – including a 32-meter dish, one of the largest in Northern Europe – which are used to study radio signals from cosmic objects. Given the scale and complexity of space, collaboration has always been essential, and VIRAC has long been involved in international and EU-funded projects. Since 2009, VIRAC has participated in a series of projects under the “RadioNet” umbrella, aimed at strengthening radio astronomy research across Europe by increasing access to facilities, advancing technology, encouraging institutional collaboration, and supporting the growth of young scientists.


The ORP project represented the next step, merging the efforts of radio and optical telescope communities into a single coordinated program. By integrating facilities observing across the radio, sub-mm, infrared, and optical wavebands, ORP enabled seamless access for European researchers to an unparalleled array of observatories.


With a total budget of €15 million, of which €60,000 was allocated to VIRAC and Ventspils University, the project supported VIRAC’s active participation in multiple scientific and collaborative activities.


Among these activities, VIRAC regularly participates in EVN (European VLBI Network) observation sessions, held three times a year, as well as in monthly real-time e-VLBI sessions and EVN-lite observations, which serve as supplementary components to the main EVN observation programme. Participation in these activities has been actively supported and facilitated through the ORP (Opticon RadioNet Pilot) project.


Additionally, VIRAC researchers are actively involved in the international scientific community, regularly attending major conferences and participating in training programs and exchange visits at leading European observatories.


Activities such as transnational access to European ESFRI and ERIC research facilities, training programs, and support for the astronomical community will continue through one of the most significant outcomes of the ORP project—ACME (Astrophysics Centre for Multi-Messenger Studies in Europe). This new initiative aims to integrate not only optical and radio astronomy but also other branches of astrophysical observation, including gravitational waves, neutrinos, and cosmic rays, fostering a truly multi-messenger approach to astronomy.


This project has received funding from the European Union's research and innovation programme HORIZON 2020 under grant agreement No 101004719.

Electronics engineering students from Ventspils University of Applied Sciences (VUAS) developed a probe that carried a can of “Rudy’s Kombucha” into near space, reaching an impressive altitude of 28,690 meters – nearly 30 kilometers above the Earth’s surface. While trying to locate the probe afterward, the students encountered major GPS signal disturbances across the Kurzeme region, so they called on radio amateurs for assistance. Working together, they successfully located the probe near Dobele. The space mission probe was equipped with a GoPro camera that captured both the launch and the breathtaking flight. After the controlled explosion of the probe’s balloon at nearly 30 kilometers altitude, a parachute opened, ensuring the can’s safe return to Earth. The probe was launched from Ventspils airfield and, after flying approximately 140 kilometers, landed near Dobele. Jānis Šate, Director of the Electronics Engineering study program at Ventspils University of Applied Sciences, explained: “The company knew that our students develop probes, and they had the idea to attach a beverage can and launch it into space. Technically, it’s more accurate to say it was launched into the stratosphere. We discussed it in August, and within a few months, the electronics engineering students built the probe. It’s a group project in the third year of studies, and this collaboration added extra value. The most challenging part of launching the probe is creating the electronic system attached to the parachute and helium balloon. The balloon rises to about 30 kilometers, where air pressure drops, the balloon bursts, and the probe descends to Earth. Launching it is easy – the hard part is tracking and recovering it afterward. A GPS navigation system is required to continuously transmit the probe’s location. The students’ task was to design an electronic system that can operate in the stratosphere, where temperatures drop to –40°C.” “We coordinated the launch with the Civil Aviation Agency since air traffic is affected, and we also arranged it with Ventspils Airport. Eventually, the probe was found near Dobele, though there were unexpected complications – due to the global situation, GPS communications are regularly disrupted from Königsberg (Kaliningrad, Russia). Unfortunately, we launched on one of those days when signal interference over Kurzeme and the Baltic Sea was particularly strong. That meant that when the probe ascended above ten kilometers, our system showed it was no longer over Kuldīga, but over Kaliningrad. From there, spoofed GPS signals were being transmitted to mislead moving objects.

In October, VUAS COLOURS WP5, headed by Lasma Asme, joined other representatives from COLOURS partner universities gathered at Garage33, Paderborn University, Germany, for a dynamic CoLab dedicated to Mental Health, Body Image, and Equality, Diversity, and Inclusion (EDI). The three-day event, which is part of the COLOURS CoSpace initiative, brought together students, researchers, and staff from across Europe to exchange perspectives and co-create innovative approaches under the smart specialisation area of Health and Well-being. Participants from a very diverse background, under the moderation of Dr Christine Hante-Koch and Dr Alena Diedrich, discussed how issues like body dissatisfaction, eating disorders, anxiety, and depression are closely connected and how promoting a positive body image can make a real difference for people’s health. Using design thinking processes, the group also worked on the importance of creating fair and inclusive support systems that meet the needs of different communities, including women, LGBTQ+ individuals, and people facing disabilities, financial struggles, or migration challenges. The participants were divided into 4 groups and had cases ranging from how to deal with women who survived breast cancer, to isolated international students living in other countries, and how to make gamers more active while utilizing their special skills and enlarging their comfort zone. At the end of the event, each group pitched their ideas, solutions, and next steps. These solutions were evaluated and challenged by a panel of experts from multiple disciplines, with the example of Martin Persson, Professor of Health Sciences at Kristianstad University. The CoLab encouraged teamwork, creativity, and cultural exchange. The ideas developed in Paderborn will help shape future COLOURS activities and strengthen collaboration between partner universities committed to building healthier and more inclusive learning environments and society at large.
