 note = {Tokai University has been conducting research on ambulances and related onboard systems for transmitting video images from vehicles in motion via the quasi-zenith satellite, which are scheduled to be launched by the Communications Research Laboratory (CRL) and the NASDA. This paper describes a newly-developed high-precision satellite tracking system, which has been developed for use with this system. The core of this tracking system comprises a few mutually complementing independent signal processing subsystems. Within this system, the absolute coordinates of the satellite are estimated by a quadrant detector (QD), while its relative coordinates are estimated by a GPS-based continuous kinematic positioning technique and calculations of six orbit elements. As it is intended to use Ka-band transponder and to use narrow beam antenna of the vehicle. So here, it would be desirable to discuss the effect of absolute coordinate with the quadrant detector to track satellite at urban area., 資料番号: AA0046101001, レポート番号: NAL SP-58T},
