Abstract
In view of the fact that non geostationary satellite constellation is becoming more and more complex and it is difficult to calculate and observe directly, this paper mainly studies the inter satellite interference of NGSO constellation. Firstly, the distribution of NGSO and various interference scenarios are comprehensively analyzed to enrich and improve the existing inter constellation interference scenarios of satellite system, and the direct interference between constellations in the same system is analyzed. Then, the data of Leo electromagnetic satellite are analyzed, and the inter satellite link interference of NGSO constellation system is calculated. Using the concept of relative interference time, the time distribution characteristics of interference are visualized, and the time characteristics of interference in different scenes are analyzed. The inter satellite link interference of large-scale NGSO satellite constellation system is analyzed from multi-dimensional perspective, and the simulation is carried out. The implementation results of the strategy prove that there is interference in the inter satellite links of large NGSO satellite constellation system. The corresponding signal analysis strategy is designed, and the data processing method of interference data is proposed.
