Paper Abstract

In satellites attitude measurement, Infrared Earth Sensor (IES) is one of the key components. In order to accomplish the testing and calibration of IES, a signal stimulated source is required to provide electrical earth-wave signal, so the system design of Electrical Signal Source of Infrared Earth-Wave (ESSIEW) is very important during the R&D and test of IES. Traditional system design of ESSIEW used digital circuits to implement so that its precision and security and testing efficiency are low. By analyzing the task and requirement of testing and calibration in the uninstalled IES, a new system design is proposed. The new system design includes two parts: hardware system and software system. The hardware system implements by FPGA technology and DAC transformation technology, and the software system implements by main-control software on CPU board and FPGA solidified software. The experiment and application results show that the system of new design presented in this article has characteristics of high precision and high security and full functions, improves the testing performance and efficiency of IES and satisfies with signal testing requirement of the electrical signal source.
