卫星多体制测控地面测试系统设计

Design of Satellite Multi-system TT & C Ground Test System

随着航天技术的不断发展,卫星功能日趋复杂,对卫星测控分系统的功能提出更高的需求,要求同时支持对地非相干扩频测控、中继测控、扩跳频测控及测量数传测控体制,对卫星测控系统地面测试平台多体制支持、通用化及自动化测试能力、可靠性提出了更高要求;文章研究了卫星多体制测控地面测试平台系统设计方法,采用了多通道测控地检通道复用、基于数据库的通用化配置及自动化测试技术,应用于某遥感卫星的地面测试,测试结果表明:该平台运行稳定,取得了良好的使用效果,满足了卫星多体制测控地面测试需求。

With the continuous development of space technology, satellite functions become more and more complex, higher requirements for satellite tracking, telemetry and control(TT&C) subsystem are proposed. It is simultaneously required to support the TT&C such as incoherent spread spectrum, relay terminal, DS/FH hybrid spread spectrum, measurement data transmission, which puts forward the higher requirements for multi-system support, generalization, automatic testing capability, and the reliability of ground test platform on the satellite TT&C system;The satellite multi-system TT&C ground test platform system design is studied in this paper, the multi-channel TT&C ground test channel reuse, database-based universal configuration and automatic test technology are applied in the ground test of a remote sensing satellite. The test results show that the platform operates stably, achieves good application results, and meets the requirements of the satellite multi-system TT&C ground test.
