We’ve finalized the last stage of the radiation tests of the AGGA-4 advanced integrated circuit which is the key component of the space-grade GNSS receivers. The AGGA-4 was exposed to the protons, and being monitored by our test environment.
In the nearest future, AGGA-4 will be running the space-grade GNSS receivers installed on Earth observations, navigations, telecommunication satellites, as well as launch vehicles. The test programme aims to verify the operation of the AGGA-4 during exposure to the space radion, in particular, heavy ions and protons. The tests were held at the Belgian Université Catholique de Louvain and Swiss Paul Scherrer Institute.
– We have managed to collect a lot of valuable data during the radiation test programme, pertaining to the operation of the AGGA-4 circuit. At the moment the consortium we lead is starting the data analysis stage which is to be followed by issuing of the final test report. Passing the document to ESA and subsequent approval issued by the technical officer would formally bring the project to a closure. It is worth to stress the fact that the results of our research, alongside testing the AGGA-4 circuit itself, would also provide us with numerous important pieces of information, useful for the space industry engineers and designers. – Karol Brzostowski, Head of the Satellite Applications and Services Department of Astri Polska, AGGA-4 Project Coordinator
