Link Analyzing and Simulation of TDRSS Based on OPNET

The TDRSS is a network of communication satellite and ground stations used by NASA for space communications. In the article, we do an accurate link analysis based on TDRSS and simulate the communication between the two satellites by using OPNET, the use of actual and real data and the final BER result show that such a communication link is feasible using small LEO satellite which is a part of a satellite constellation. All of the work lay foundation of further satellite network simulation.
