Abstract：According to the technical requirements of the satellite attitude and orbit control subsystem semi-physical simulation system, a calibration device for the solar sensor simulator is described. The calibration device uses FPGA and AVR microcontroller as the control core, micro-board computer to simulate dynamic computer, which uploads and downloads instructions through the network port. What’s more, the calibration device builts signal conditioning circuit, high-precision acquisition module, data solving module inside, etc. The calibration device is highly integrated, which replaces the complex calibration system composed of digital instruments and dynamics computers, effectively reduces the cost, improves the efficiency by about 40%, and realizes the fast online calibration of the solar sensor simulator in the whole process.
