基于三层卫星网络的星间链路性能分析
Performance Analysis of the Intersatellite Links Based on 3-Layer Satellite Networks
摘要
Abstract
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 Ka-band and laser links under the preset intersatellite transmission system, link parameters, transmission loss, etc. Results show that 0. 5m antennas only need 5W transmitting power to provide an intersatellite data transmission rate higher than 2Mb/s in the Ka-band and the laser links data transfer rate can achieve to more than 2Gb/s with 0. 5W launching power and the 0. 25m antenna diameter. The laser links greatly improve the communication ability compared with the microwave frequency band. This serves as a reference for the 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 in the future.关键词
