An Analysis and Comparative Study of the Performance of Intersatellite Links of 3-Layer Satellite Networks
Performance analysis of intersatellite links is the basis for establishing intersatellite communications. A 3-layer satellite network containing GEO, IGSO, and MEO satellites is used as an example to simulate the variation range of distance interlayer satellites of the 3-layer satellite network and to analyze the performance of GEO-IGSO, GEO-MEO, and IGSO-MEO links in S-band and Ka-band under the preset intersatellite transmission system, link parameters, transmission loss and without regard to the error of the intersatellite pointing accuracy. Results show that Ka-band is more favorable for improving the performance of intersatellite links. This serves as reference for selection of the transmitting power, antenna diameter, and intersatellite information transmission rate of satellites during the establishment of intersatellite links for 3-layer satellite networks.
