A GEO Satellite Positioning Testbed Based on Labview and STK

摘要

With the increasing use of high orbit satellites, the global navigation and positioning system (GNSS) for high orbit satellite positioning has become a hot research topic. In this paper, the GNSS-based high-orbit spacecraft orbit determination algorithm is built to simulate and verify the system, and the system state obtained by system-level simulation is verified in real time. Traditional STK simulation, parameter changes need to be manually adjusted, so this article uses Labview to control the STK from the bottom, automatically set the parameters, to facilitate related research, so as to verify the visible stars, DOP deserves specific values and dynamic trends.
