The telemetry, tracking, and command (TT&C) network is one of the key issues for regional navigation satellite system. Firstly, the domestic deployment of TT&C stations was discussed. The observability on navigation satellite constellation based on domestic stations was analyzed by means of grid computation. Then, the observing geometric structure intension on satellites was synthesized by the position dilution of precision (PDOP), and the influence of the station's location on satellite orbit determination precision was valuated by the condition number of normal matrix. The simulation shows that the TT&C stations located in the limited span of Chinese territory and the existing TT&C resources can accomplish the TT&C task. Finally, the setting of stations abroad was considered and simulated, and it verified that the joining of the stations abroad, such as the station in Perth in Australia, can improve the observing geometric structure intension and satellite orbit determination precision.
