作为实现国内卫星通信用地面站的第一步而建设的卫星通信实验站,就天线传动,自动跟踪,遥测指令和数据处理各系统进行综合试验。明确了系统的综合特性,基本上得到满意的结果,从而证实设计的正确性。天线传动和自动跟踪系统中,根据使用模拟卫星取得的过渡特性,引导跟踪收敛轨迹特性,跟踪误差的伺服系统的基本特性和用现有卫星的跟踪试验而明确了卫星的跟踪技术。根据与模拟卫星组合进行的地面站试验证实遥测指令和数据处理系统的综合特性是正确的。此外,利用现有卫星的轨道予报和确定轨道程序的特性试验,根据实用的轨道予报和观测值就可决定初期轨道。
As a satellite communication experiment station constructed as the first step to realize the ground station for satellite communications in the country, a comprehensive test was conducted on the systems of antenna transmission, automatic tracking, telemetry command and data processing. Clarified the comprehensive characteristics of the system, basically satisfactory results, thus confirming the correctness of the design. Antenna transmission and automatic tracking system, based on the transition characteristics obtained by the use of simulated satellites, guide the trajectory characteristics of the convergence trajectory, the basic characteristics of the servo system tracking error and satellite tracking technology with the existing satellite tracking. Ground station tests conducted in combination with simulated satellites confirm that the combined nature of telemetry commands and data processing systems is correct. In addition, the use of existing orbital satellites to report and determine the characteristics of orbital procedures tests, based on practical orbital observations and observations can determine the initial orbit.
