ERS-1 orbit calculation with the GEOSAT software
Abstract
An analysis performed with the Geosat software, which was developed for high precision analysis of satellite tracking and Very Long Baseline Interferometry (VLBI) data for geodetic and geodynamic applications, is reported. For applications to ERS-1, a realistic surface force model is used together with the Jacchia 77 atmospheric model, semi-daily drag coefficients, a 1 cpr sinusoidal along track acceleration, and the Goddard Space Flight Center (GSFC) JGM 2 gravity model. ERS-1 orbits were derived for 5.5 day arcs of laser tracking data between 6 Jul. - 12 Aug. 1992. Comparisons between overlapping orbits indicate a radial accuracy of around 14 cm.
