Design and Implementation of System-level Test for HXMT Satellite

归纳了硬X射线调制望远镜(HXMT)卫星的系统级测试特点,其中惯性空间动中探测与X射线望远镜性能测试为相对传统遥感卫星特有的测试需求。提出了适用于HXMT卫星系统级测试的动中探测姿态机动测试方案,通过设计GPS动态仿真模拟器和星地高精度时间统一实现姿态机动闭环测试系统;提出了X射线光管打靶测试方案,利用靶板上不同金属材料的荧光效应产生不同谱段特征的X射线,并对热试验罐内测试进行了针对性设计。整星测试结果表明:测试系统设计合理可行,有效验证了HXMT卫星各项功能、性能指标的正确性,可为后续空间射线探测科学卫星开展系统级测试设计提供参考。

The characteristics of the HXMT(hard X-ray modulation telescope)satellite system-level test are summarized.The detection in inertial space motion and the performance test of X-ray telescope are the special test requirements of HXMT satellite compared with traditional remote sensing satellite.An attitude maneuver test system for HXMT satellite system-level test is proposed.The closed-up attitude maneuver test system is realized by designing GPS dynamic simulation simulator and satellite-ground high precision time unification.An X-ray tube shooting test system is proposed.X-rays with different spectral characteristics are produced by the fluorescence effect of different metal materials on the target plate,and the test in the thermal test tank is designed.The test results show that the design of the test system is reasonable and feasible,which validates the correctness of each functional performance index of the HXMT satellite effectively,and provides a reference for system-level test design of the follow-up space ray detection scientific satellites.
