一种多体制的卫星测控模拟器

A Sort of Satellite TTC Multisystem Simulator

提出了一种多体制的卫星测控模拟器的设计,兼容统一载波测控体制和扩频测控体制,也兼容脉冲编码遥测格式和高级在轨系统遥测格式。采用"软件无线电"的思想,在相同的硬件平台下,用不同的基带软件实现不同的测控体制,通过与不同的上下变频器相连,实现不同的测控点频。文章详细阐述了一种多体制卫星测控模拟器的系统组成、重要部分的工作原理和应用。

A sort of design of satellite TTC multisystem simulator is presented, which as the compatibility of unifsed carrier TTC system with spread spectrum TTC system, and Pulse Code Modulation telemetry format with AOS （Advanced Orbiting System） telemetry format. By using of software radio theory, the simulator can provide different TTC Systems by loading different base-band softwares at the same hardware platform. By Using different upconverters and downconverters, it can produce different frequencies. The sort of satellite TTC multisystem simulator＇s composition and the working of its important components is analyzed, and its applications are expected.
