深空微波高精度测距测速技术
High-accuracy Radio Ranging and Velocity Measurement Technology for Deep Space Exploration
摘要
Abstract
To fulfill the future deep space exploration mission,the radio measurement accuracy must be en-hanced at least one order. The current situation of ranging and velocity measurement of China's deep space tracking,telemetry and command( TT&C) system is analyzed,and analysis of main error budget and accruacy improvement suggestions are provided. For the attached measurement error of interplanetary plasma,a multi-frequency link scheme is proposed to isolate the interplanetary plasma. The theoretic analysis shows that the multi-frequency link scheme makes the measurement effective under any Sun-Earth probe angle. The station delay bias online monitoring is presented to reduce the station residual error from meters to decimeters.关键词
