In this study from FY 2003 to FY 2004, as for an inter-satellite ranging subsystem for the Quasi-Zenith Satellite (QZS) to improve the orbit determination accuracy, we have conducted system designs, defined specifications of the subsystem, manufactured critical part models and evaluated them for a laser ranging system and a radio ranging system respectively. As a result, we have developed a table comparing functions, performances, and physical characteristics of the subsystem for each ranging system. The results of the study were utilized for design activities of 'High Accuracy Positioning Experiment System Using Quasi-Zenith Satellites System' project., 資料番号: AA0049054052, レポート番号: JAXA-SP-05-008}, title = {衛星間測距装置の研究}, year = {2006} }
