Applications of Delta Differential One-way Ranging （△DOR） to Lunar Exploration Program
摘要
Abstract
Delta Differential One-way Ranging （△DOR） is used for high precision angle measure- ment in many deep space exploration programs. The fundamentals of ADOR are introduced. Also, recommendations about ADOR of CCSDS （Consultative Committee for Space Data System） are presented. According to the high precision and real-time navigation requirements, the ADOR measurement schemes are designed for China＇s lunar exploration program whose current object is soft-land on the moon. The angle measurement precisions are analyzed in terms of the current performances of on-board and ground TT＆C equipments. The resolution of the cycle ambiguity is presented. Research results show that the angle measurement precision is 25 nrad, which corresponds to about 10 m on the moon. Further, the cycle ambiguity of DOR measurements can be resolved correctly.关键词
