Proposed satellite position determination systems and techniques for Geostationary Synthetic Aperture Radar

Abstract

This paper proposes two different calibration techniques for Geostationary Synthetic Aperture Radar (GEOSAR) missions requiring a high precision positioning, based on Active Radar Calibrators and Ground Based Interferometry. The research is enclosed in the preparation studies of a future GEOSAR mission providing continuous monitoring at continental scale.

Interferometric orbit determination for geostationary satellites

“…Such orbital determination requirements are well beyond the usual systems used to manage repositioning of satellites in geostationary orbits. To achieve an accurate satellite orbit, two possible precise systems have been discussed in [6].…”
