Final Presentation NAVISP EL1-070 “Advanced MEOSAR Test Beacon Setup”

The final presentation of the Advanced MEOSAR Test Beacon Setup (AMTBS) activity, developed by Thales Alenia Space in France under ESA’s NAVISP-EL1-070 project, will summarize the outcomes of this initiative. The project focused on developing and testing in a real environment a 4x4 meters UHF Digital Beamforming Antenna Array as MEOSAR test beacon. This antenna system is able to emulate every kind of beacon trajectory, thanks to the generation of SAR (Search And Rescue) signals embedding the effects corresponding to an emulated beacon motion. The main challenge of this ground station is the concurrent generation of more than 10 beams, where each beam targets one MEO satellite and nulls the others. The presentation will detail the design of this UHF antenna array including digital beamforming algorithms. The results from end to end tests, with broadcasts towards MEOSAR satellites, and localisation of the emulated moving position by operational Cospas-Sarsat ground stations (MEOLUTs) will also be presented.
You will gain insight into the technical approach and the achieved performance metrics, as well as potential directions for further development.
