Software design in data management equivalent device for the calibration

A control software is designed for a data management equivalent device about the calibration. As a new design method, it is to add self-calibration method to data management equivalent device of satellite, making the calibration into the device itself, which improves the dependability of the system. Research on the self-calibration function, it is used the least square basic principle to curve fitting for calibrating the AD of the hardware, and improve sampling resolution. On the basis of the average segmentation of parameter calibration, which could improve the accuracy of the test for the device. The paper expounded the designing to software. The designing indicates that the calibration can fulfill the equivalent device, reasonable designing of the software.
