—The Relay Satellite acts as the bridge between the
user spacecrafts and the ground stations. The link performance
between the relay satellites-Tianlian-1 and LEO terminals is
analyzed using STK software in this paper. For small user
terminal system, the link performance of the user spacecraft to
the relay satellite has great relation to characteristic of the
antenna pattern except for the orbit of the user spacecraft.
Taking the satellite at height of 500km earth orbit for
consideration, the access simulation are performed at different
orbit inclination and different antenna pattern types of the user
spacecrafts. From the simulation result, the relationship among
the antenna pattern, the orbit inclination and the total access
duration is shown intuitively, the access region and the access
times are also shown directly at the same time. The simulation
results are helpful for the system design for lower power cost
and longer access time.
