Four-way Doppler measurements toward the SELENE Main Orbiter above the lunar far side will be carried out by the Relay Satellite Transponders (RSAT) on Rstar and the Main Orbiter. Phase-delay differential VLBI observations will be performed for multi-frequency carrier waves emitted from the Differential VLBI Radio Sources (VRAD) on Rstar and Vstar. We have executed proto-flight tests and confirmed that instruments and the ground system of RSAT and VRAD have enough performances to improve the accuracy of the lunar gravity field., 資料番号: AA0063223013, レポート番号: JAXA-SP-06-015}, pages = {85--90}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {SELENEの3機の月周回衛星を用いた軌道決定による月重力場観測システム}, volume = {JAXA-SP-06-015}, year = {2007} }
