摘要: The first ESA (European Space Agency) Earth explorer core mission GOCE (Gravity field and steady-state Ocean Circulation Explorer) was launched on 17 March 2009 into a sun-synchronous dusk–dawn orbit with an exceptionally low initial altitude of about 280 km. onboard 12-channel dual-frequency GPS (Global Positioning System) receiver delivers 1 Hz data, which provides the basis for precise determination (POD) such very orbiting satellite. As part European Gravity Consortium Astronomical Institute University Bern Department Observation Systems are responsible satellite within High-level Processing Facility. Both quick-look (rapid) solutions produced typical latencies day 2 weeks, respectively. This article summarizes special characteristics presents POD results months shows that both latency accuracy requirements met. Satellite Laser Ranging validation 4 7 cm is achieved reduced-dynamic kinematic Rapid Science Orbit solutions, Precise at level cm.
