STK-based Telecontrol and telemetry of space-based real-time visualization system has been studied, on the basis of STK/VO. It constructs a space mission for real-time visualization system and the purpose is to monitor the performance of the whole process of dynamic scenes by Telecontrol and telemetry through the establishment of space-based real-time visual system. Therefore, it can provide a convenient, intuitive and effective means for command and decision-making in the space mission. Firstly, analyze the data based on real-time Telecontrol and telemetry STK visualization features. secondly, proposes systematic design principles and modules of three-dimensional modeling, real-time data-driven methods and STK highlight the appropriate settings. Finally, a specific application example shows the function of each module and the simulation process.
