摘要

In the recent past GPS receivers for space applications have been used in different areas. Orbit determination for different kinds of missions from LEO (Low Earth Orbit) to GEO (Geostationary Orbit) have been explored and used. For LEO satellites the usage of GPS receivers is becoming a standard. Navigation satellite systems are not only used for realtime absolute orbit determination, but also for relative navigation between multiple vehicles, attitude determination, precise orbit determination and a growing number of other areas of interest. The so-called MosaicAODS is a space-borne Altitude & Orbit Determination System developed at Astrium GmbH. It is based on the MosaicGNSS receiver, extended by a star sensor and an optional INS. In order to validate the functionality of the MosaicAODS and to ensure its proper functionality in space a modular real-time test environment has been developed, where single AODS modules as well as the full system can easily be tested. Additional to these tests, the system provides the capability to test precise and relative navigation using GPS signals for rendezvous maneuver, formation flying or spacecraft co-positioning. This paper outlines the AODS test environment and the GPS precise and relative navigation test environment.
