The aim is to evaluate the capabilities of Low Earth Orbit (LEO) Positioning Navigation and Timing (PNT) systems to advance Global Navigation Satellite Systems (GNSS).
Implemented through two parallel contracts for mini constellations with varied payloads.
Validated L/S-band and C/UHF-band payload technologies via experimental campaigns.
Demonstrated onboard Orbit Determination and Time Synchronisation (ODTS) and 5G NTN signal broadcasting.
Demonstrated frequency diversity with successful PNT signal transmission across multiple bands.
Validated core technologies and expanded capabilities for two-way communication and integrity monitoring.
Provided critical performance data for enhancing existing GNSS systems like Galileo and EGNOS.
