摘要：

In the context of scientific investigations related to the CHAMP project and other upcoming LEO missions, the GeoForschungsZentrum Potsdam (GFZ) initiated the development of an efficient real-time on-board orbit estimation and propagation software called POPE. The methods specific to POPE are in fact adaptions of orbit prediction algorithms that are being in operational use for the PRARE system on-board METEOR 3/7 and ERS-2 for several years. Simulation studies show that orbit elements generated by POPE from on-board GPS measurements suffice to bridge a gap of up to one week without GPS data with position errors of 10 to 20 km on the average for LEO orbits at 300 km altitude.
