Abstract

The invention discloses an electric signal resource device to swing sweep infrared earth sensing test calibration which is made up of the CPU, analog output module, the signal resource generating module, the power supply and the LCD. The CPU is connected with the analog output module and the signal resource generating module by the STD bus; the LCD is connected with the CPU by the VGA interface. According to the need signal and the time sequence of test calibration, the CPU works out the signal resource generating data according to the distributed parameter which the data controls the signal resource generating module and the analog output module. At the same time, it outputs the signal need by the sensing device calibration to finish the test calibration.

Description

technical field [0001] The present invention relates to a signal generating device, more particularly, to a signal source device suitable for testing a test calibration system of a swing scanning infrared earth sensor. Background technique [0002] The oscillating scanning infrared earth sensor is the key measurement component for the determination of the attitude of the three-axis attitude stabilization satellite in the middle and high orbits. The signal processing circuit and other components rely on the swing frequency of 5Hz to realize ground scanning, measure the attitude change of the satellite's pointing axis relative to the satellite-ground line, thereby obtaining the satellite's attitude information, and using it as the attitude information feedback of the control system to realize Stabilization control of satellite attitude. [0003] In the development process of the satellite attitude control system, the system test is an important link, and the test and calibrat...
