Webinar on NAVISP project: Deployable Satellite Navigation Antenna

We are pleased to share an update from the ESA Navigation Innovation and Support Program (NAVISP), where Radientum has been part of the consortium developing a new deployable GNSS antenna concept for small satellites. The final results of the NAVISP EL1-083 “Deployable Satellite Navigation Antenna” project will be presented in an upcoming webinar hosted by the European Space Agency.

The consortium — Huld, Finnish Meteorological Institute (FMI), and Radientum — has worked together to address the growing need for compact, high-performance navigation antennas for small spacecraft such as CubeSats. As the use of small satellites expands across commercial and scientific missions, the market increasingly requires antenna solutions that combine reliability, low volume, and strong PNT (Positioning, Navigation and Timing) performance.

The project set out to transform a deployable antenna idea from an early conceptual stage toward a more mature and test-verified prototype. This included progressing the technology from TRL1 to TRL4, validating both the electromechanical design and RF performance.

During the development, the team explored innovative approaches for creating an antenna that can be stowed compactly during launch and reliably deployed once in orbit. The work included electromagnetic design, mechanical concept development, prototyping, and performance testing in relevant environments.

NAVISP is ESA’s strategic program supporting innovation and competitiveness in Europe’s PNT sector. The program enables research, technology development and commercialization of new concepts that enhance or complement existing navigation systems. Through funding, guidance and industry collaboration, NAVISP supports companies in taking their PNT ideas from concept to market.

The final results of the NAVISP EL1-083 project will be presented in a public webinar hosted by ESA.
