| 我国出口的商业地球同步卫星其地面测控系统一般由地理上相隔一定距离的两个地面站组成，每个站有一个卫星控制中心（SCC）和基带、链路及天线系统。为了提高地面测控系统的可靠性，减少操作人员，重点研究了两个卫星控制中心、两个地面站的测控（TT&C）设备之间相互融合与互操作问题。提出通过统一两个站SCC、自动监控系统（MCS）、基带的接口，保持SCC数据库同步，实现两个站的融合。在MCS的配合下，在遥测、遥控、测距和校零模式下可以实现双站的互操作，每个站的SCC可以通过任何一个站的基带、链路及天线接收下行遥测数据，发送上行遥控和测距信号。所提出的双站融合与互操作设计在多个出口卫星项目地面测控系统中得到应用，降低了系统运行的成本。 |

| Abstract: |
| In general,the TT&C system is composed of two stations separated on geographical positions for the foreign commercial Geostationary Eearth Orbit(GEO) satellites exported from China. Each station includes a satellite control center(SCC),baseband equipment(BBE),RF links and antenna. In order to improve the reliability of ground control system and decrease the operator number,it is necessary to make integrated design for two independent stations. This paper brings forward that two stations are integrated together by means of designing the interface of SCC,monitoring and control system(MCS) and BBE used in two stations and keeping two stations′ SCC database synchronous. Under the cooperation of MCS,the interoperations between two stations are achieved in different working mode of telemetry,telecommand,ranging and calibration. Each SCC can receive telemetry data,send telecommand and ranging signal to satellite through any BBE,RF link and antenna in two stations. The design method of two stations′ integration and interoperation has been implemented in many satellites exported from China and the system running cost is decreased clearly. |
