红外地球敏感器测试用电信号源软件实现

Software design for electrical signal source of infrared earth sensor

在卫星姿态测量中,红外地球敏感器为核心部件。在研制红外地球敏感器过程中需要红外地球波电信号源为其提供电激励信号,根据红外地球敏感器测试要求设计了红外地球波电信号源的软件系统。软件系统主要包括CPU板上主控软件和FPGA固化软件两部分,分别实现对红外地球波电信号源信号发生的控制和专用信号发生模块信号输出的控制。调试结果表明软件系统具有高可靠性、功能全面的特点,满足红外地球敏感器测试用信号源实时性和高精度的要求。

Infrared earth sensor is one of the key components in satellite attitude measurement. In order to accomplish the calibration and test of infrared earth sensor, a signal stimulated source is required to provide electrical earth wave signals in the process of R&D. According to the test requirement of infrared earth sensor, a software system of electrical signal source is designed. The software system contains two parts——the software of main control on CPU board and the FPGA solidified software, which control ...
