Airbus’s LEOPARD Navigation Unit delivers position, velocity and time to Low Earth Orbit satellites. LEOPARD is a Global Navigation Satellite System (GNSS) Receiver also supporting an optional star tracker. This new navigation unit is fully based on flight-proven hardware and takes advantage of previous GNSS receiver experience at Airbus, in particular with our MosaicGNSS and LION GNSS receiver products. Airbus GNSS receivers have over 15 years in-orbit heritage and more than 100 cumulated years in orbit on a global set of missions and orbits.
LEOPARD belongs to the Airbus New Space PureLine product family. PureLine was originally developed for mega constellation applications, with first launch in early 2019. This cost-effective approach is based on Airbus technological heritage and batch procurement, utilizing mainly automotive COTS parts and processes.
