Stability analysis of satellite communication link

The performance of communication link is very important to the quality of communication. Once the device is designed in satellite communication, its basic performance is difficult to change. The satellite tool kit’s powerful capabilities can make communication simulation in extreme situations, enabling the satellite to meet its design requirements as best as possible prior to launch. It is of great significance to study the antenna diameter of transmitter, transmitting power, angle of receiver and receiving frequency, which have important influence on communication performance. Larger antenna diameter and angle of receiver could get more communication links, while the transmitting power has little influence. The research provides mass of data, which are of great help to the designer to analyze the communication performance under extreme conditions.
