Abstract
The Relay Satellite acts as the bridge between theuser spacecrafts and the ground stations. The link performancebetween the relay satellites-Tianlian-1 and LEO terminals isanalyzed using STK software in this paper. For small userterminal system, the link performance of the user spacecraft tothe relay satellite has great relation to characteristic of theantenna pattern except for the orbit of the user spacecraft.Taking the satellite at height of 500km earth orbit forconsideration, the access simulation are performed at differentorbit inclination and different antenna pattern types of the userspacecrafts. From the simulation result, the relationship amongthe antenna pattern, the orbit inclination and the total accessduration is shown intuitively, the access region and the accesstimes are also shown directly at the same time. The simulationresults are helpful for the system design for lower power costand longer access time.
