卫星控制分系统地面测试系统的设计是姿轨控分系统设计的重要部分。本文经软、硬件的充分论证后给出了基于PXI总线的硬件采集系统和XPC软件仿真环境下的卫星姿轨控系统综合仿真测试的设计方案，并结合某型号卫星姿轨控分系统的测试需求进行具体的项目开发；实践表明该测试系统具有较强的可扩展性和二次开发能力、结构灵活、体积小、测量精度高、抗干扰能力强等优点，可以应用于相应的中低轨道卫星的控制分系统测试。

Design and Implementation of Satellite of Control Subsystem Synthesis Test System

The design for the ground test system of the control system is very important for the subsystem design. After a detailed study on hardware and software scheme, we present the design scheme of the synthesis simulation of satellite orbit control system, which consists of the PXI-based hardware architecture and xPC-based software system, By integrating the real requirement of control subsystem of any satellite type, we implement the simulation system. The results show that the test system has good expansibility to be redeveloped, small volune, high measuring accuracy and strong anti - jamming capability. It can be used in the test of the control subsystem for the medium and low orbit satellite.
