As a multi-user shared space information transmission asset, the Tracking and Data Relay Satellite System (TDRSS) is critical in establishing an efficient resource scheduling mode, in order to maximize the utilization of system resource and bring the service efficiency into full play. The thesis takes the U.S. Tracking and Data Relay Satellite (TDRS) System(More)
With high resolution satellites observation scope expanding, observation means increasing, observation data volume enlarging, all kinds of emergency tasks from military and civilian fields are more and more. The high resolution satellites need fast investigation, rapid mobility, rapid transmission and emergency rescue ability. Since 2008 China had(More)
The data relay satellite as a typical GEO satellite application plays an important role in the TT&C and data transmission based on space. Taking into account operation and production cost of the relay satellite very high, so it is great to significantly improve the social and economic benefits as much as possible to extend the satellite in orbit life.(More)
In the general way, routine eclipse prediction methods can only provide starting and ending time prediction. However it cannot give us accurate sate switch time prediction. It does not ensure satellites safety. This paper brings up a new GEO satellite energy switching time calculation algorithm in eclipse period. This method not only provides accurate(More)
With the application field expanding of the data relay satellite in modern space technology, manned spacecraft will install the relay terminal and realize the high speed data transmission from spacecraft to control center by use of data relay satellites system. However, there are many factors such as the spacecraft regular orbit maneuver, astronauts(More)
This paper analyzes the relationships between orbit variations and MW rotation rates variations during station-keeping control and brings up a new evaluation algorithm of station-keeping control results by using variation of angular momentum. This algorithm can evaluate the control results rapidly and get precise semi-major axis, eccentricity, longitude(More)
