Abstract: | With the rapid development of Satellite communication technology,low-orbit satellite communication systems have become a new development trend.Due to limited spectrum resources,low-orbit satellite communication systems may face co-frequency interference problems with themselves and external ground and satellite systems.System interference scenarios are analyzed from the three aspects of external system interference to low-orbit satellite communication system,low-orbit satellite communication system to external system interference,and internal interference of low-orbit satellite communication system.On this basis,different interference situations are provided.The external ground interference,low-orbit satellite communication system and synchronous geostationary satellites,and the internal interference avoidance strategy of the system can provide a certain reference for the design of the low-orbit satellite communication system to ensure that the system can operate effectively and reliably. |
