深空探测对我国地面测控站升级的需求∗
Updating ground TT & C stations for deep space exploration in China
摘要
Abstract
China deep space controlling network (CDSCN)constructed and applied in lunar missions can do range and range-rate as well as VLBI together with remote control and telemetry at radio band for deep space tracking like Mars missions and other deep space exploration missions.Remote deep space exploration missions shift the direction of up-link and down-link signals because of increasing time duration of microwave transmission between aiming planets and ground.This is a challenge for remote exploration telecommunication because it is not possible to do up-link and down-link radio communications simultaneously.For a typical Mars exploration,the disadvantages of deep-space measurements with single radio antenna controlling system are analyzed.Several suggestions for updating and upgrading controlling equipments are made which are necessary for remote communication on deep space exploration missions.The up and down-links could be time-divided on a solo antenna at a given deep space tracking station.Or the up and down-links are set up in multiple stations with solo antenna each with 3-way open loop method.The DSN/JPL/NASA method are used to set up multiple antennas at each deep space tracking station,with antennas share the same time-frequency standard,and the antennas at same station realizing close-loop up and down link real-time TT & C continuously.关键词
