摘要：
After the typical Global Navigation Satellite Systems were analyzed, a novel method Tracking-Telemetry-Control (TT&C) was presented in this paper for Low Earth Orbit (LEO) satellite based on the redundant navigation message. Using this method, the LEO satellite telemetry data could be monitor and be even controlled by the mobile equipment or the mini-TT&C equipment. In order to solve the problem that the telemetry data and control command data are more than the redundant navigation message, an adaptive compression method was described in this paper based on the analysis of the command and telemetry data property. The experiment of the test navigation equipment proved the effectiveness and the efficient of the method.
