Embodiment Construction

[0036] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0037] A signaling beam design method for NGSO satellite systems that supports interference avoidance. The method is aimed at the uplink and downlink beams in the NGSO satellite system, and can be applied to a certain NGSO satellite or a multi-satellite system composed of different orbital planes. A certain NGSO satellite constellation mainly includes the following steps:

[0038] (1) For each satellite in the NGSO satellite system, according to the beam angle range and satellite orbit height set by the satellite or ground station antenna, the coverage of the antenna beam in space or on the ground is initially divided into Multiple bar wave positions;

[0039] (2) According to the antenna transmission power and transmission antenna pattern of the NGSO satellite system space segment or ground segment, determine the range of transmission techni...

Abstract

The invention discloses an NGSO satellite system signaling beam design method supporting interference avoidance, and belongs to the field of beam design. From the perspective of solving the interference problem of the NGSO satellite system to the GSO satellite system, the invention provides a targeted NGSO satellite antenna beam design method. The problem of potential interference of the NGSO satellite system to the GSO satellite system and the problem of prominent frequency contradiction between the NGSO satellite system and the GSO satellite system can be solved under the prescriptions of frequency usage priority of the international electric connection GSO satellite system.

Description

technical field [0001] The invention relates to a method for designing a signaling beam of an NGSO satellite system supporting interference avoidance, and belongs to the technical field of beam design. Background technique [0002] The main design purpose of the signaling beam of the satellite system is to transmit beacon signals to provide necessary auxiliary support for ground terminals to accurately track satellites; the second is to provide uninterrupted full-coverage signaling links for users covered outside the user beam area ; Therefore, the signaling beam has the characteristics of full-time, wide-area coverage communication. [0003] At present, due to the prosperity and development of the NGSO (non-geosynchronous orbit) satellite Internet constellation, the number of NGSO satellites that have been launched and under research is relatively large, and the GSO (geosynchronous orbit) satellites currently in orbit basically cover all geostationary orbits above the equat...
