TT＆C Communication Support for Spacecraft Rendezvous and Docking Mission Provided by Foreign Data Relay Satellites

Space-based TTC technology using data relay satellite system is a great breakthrough in modern space technology domain,and can effectively meet the TTC and communication requirements of spacecraft rendezvous and docking mission.This paper analyzes TTC and communication supports provided by tracking and data relay satellite system（TDRSS） and ARTEMIS for Automated Transfer Vehicle（ATV）/International Space Station（ISS） mission,and summarizes four features of supporting spacecraft rendezvous and docking mission by TDRSS,ARTEMIS,etc.： ①An integrated space and ground-based TTC and communication network dominated by data relay satellites system is built;②Using the single access（SA） antenna onboard TDRS spacecraft to support two user platforms within the same SA antenna beam is encouraged;③The user terminals use multiple S-band antennas to implement the continuous TTC and communication coverage;④Many nations make an effort to develop their own data relay satellite systems while enhancing the cooperation with each other.The study results show that an integrated space and ground-based TTC and communication network dominated by data relay satellites system can overcome the difficulties such as low coverage,high operational cost faced by the ground and sea-based systems,and therefore can provide the better TTC and communication supports for spacecraft rendezvous and docking mission.
