Interference assessment between solar power satellite (SPS) system and fixed satellites service (FSS)/ fixed terrestrial service (FS) systems

摘要

The Solar Power Satellite/Station (SPS )system is considered as one solution for future energy problems. On the other hand, the congestion of the GSO is very severe and there are many existing satellites on the GSO. The SPS system with 2.45 GHz transmitter, 6.72 GW power and one km square antenna on the geostationary satellite orbit (GSO) are examined. The Interference assessment between SPS system and Fixed Satellites Service (FSS)I Fixed Terrestrial Service (FS) are carried out. The SPS antenna is assumed as patch array and 4.9, 12.25, 19.6, 29.4 GHz band spurious radiated antenna gains are used for interference calculations. As a result, interference constraints in 12.25 GHz band is relatively severe. Some strategies for relaxation of interference are discussed for co-existing between SPS and FSS/FS systems.
