Establishing the inter-satellite link which connects the navigating constellation can optimize the resource of TT&C, and enhance management capacity of the ground station. For researching and validating topology, protocol and TT&C capacity of the ground station, an integrated simulating platform has been designed based on STK and OPNET. This platform includes the topology of inter-satellite link, the model of satellite node and ground station. Furthermore, the data format of telemetry between satellites and stations complies with Space Communication Protocol Specification. Finally, with constellation and stations combined, telemetry transmission is simulated in both normal mode and another mode with one satellite invalidated. Through analyzing indices like telemetry time delay and throughput, correctness and effectiveness is validated in the topology of constellation and routing algorithm. This platform has achieved a certain degree of universal property, and can provide technical method for researching other satellite communication networks.
