Abstract: The instrument display system for spacecraft, as the window for monitoring the performance parameters, navigation parameters and astronaut’s man-machine interactions, plays an important role in space missions. The traditional method to monitor the state of spacecraft is to monitor the engineering telemetry sound code, which is inconvenient for the ground control because of its poor audio-visual quality. In this paper, an instrument display software based on VC++ and OpenGL is designed and analyzed. This software simulates the multifunctional instrument display to realize the instrument’s functions of displaying the parameter information, the warning message and the device operating information. The software has been successfully applied in the ground control center.
