Envisat Precise Orbit Determination
The Navigation Office at ESOC has been closely involved in all aspects of the Precise Orbit Determination (POD) of Envisat throughout the mission lifetime. These activities started shortly after launch through membership of the Orbit Validation Team (OVT). During this time ESOC was involved in both calibration and validation of the DORIS doppler data, the SLR data and the different POD solution...
متن کاملPrecise orbit determination for the FORMOSAT-3/COSMIC satellite mission using GPS
The joint Taiwan–US mission FORMOSAT-3/ COSMIC (COSMIC) was launched on April 17, 2006. Each of the six satellites is equipped with two POD antennas. The orbits of the six satellites are determined fromGPSdata using zero-difference carrier-phase measurements by the reduced dynamic and kinematic methods. The effects of satellite center of mass (COM) variation, satellite attitude, GPS antenna pha...
متن کاملPrecise Orbit Determination for Low Earth Orbit Satellites
The precise orbit determination problem is to accurately determine the position and velocity vectors of an orbiting satellite. In this paper we review the general contents of the orbit determination process, with particular emphasis on Low Earth Orbit (LEO) satellites. The different orbit determination approaches and the different force models contained within are briefly discussed. The two mai...
متن کاملSentinel-1A – First precise orbit determination results
Sentinel-1A is the first satellite of the European Copernicus programme. Equipped with a Synthetic Aperture Radar (SAR) instrument the satellite was launched on April 3, 2014. Operational since October 2014 the satellite delivers valuable data for more than two years. The orbit accuracy requirements are given as 5 cm in 3D. In order to fulfill this stringent requirement the precise orbit determ...
متن کاملImproved Ers and Envisat Precise Orbit Determination
For over a decade, the Delft precise ERS-1 and ERS-2 orbits have been used in many scientific investigations based on ERS altimeter and interferometric SAR data. This orbit computation is now continued for Envisat, with an unprecedented accuracy due to better tracking data and lower force model errors. Orbit errors due to inaccuracies in the Earth’s gravity model, which have been the main focus...
