A method for realizing compatible coexistence of new and existing ngso constellation communication systems

Abstract

An embodiment of the present invention discloses a method for realizing the compatibility and coexistence of a new and existing NGSO constellation communication system, including: a satellite of the new NGSO constellation communication system performs control-level signaling interaction with a ground user station through a first signaling beam; The combined coverage of the signaling beams of each satellite in the newly-built NGSO constellation communication system ensures that at least one coverage is achieved on the earth's surface; the satellites of the newly-built NGSO constellation communication system communicate with the ground user station through the first user beam, Wherein, the spot beams of each satellite are controlled to point to different wave positions in different time slots, the fixed wave positions form a first range, and the first range is consistent with the primary coverage range; the ground user station Acquire currently available spectrum resources, and send their location information and spectrum occupancy information to satellites covering the user station through the first signaling beam.

Description

technical field [0001] The present invention relates to the field of satellite communication. More specifically, it relates to a method for realizing compatible coexistence of new and existing NGSO constellation communication systems. Background technique [0002] In recent years, many domestic and foreign companies have proposed low-orbit satellite Internet constellation systems that can provide data services and realize Internet transmission functions. This type of satellite communication constellation system includes the following characteristics: A giant constellation of satellites; from the perspective of constellation composition, it is mostly composed of small satellites operating in low earth orbit (LEO). According to the current satellite network data declaration status of various satellite Internet companies in the International Telecommunication Union (ITU), a number of satellite communication systems have submitted applications, planning to use all available Ku,...

Problems solved by technology

Due to the limited radio spectrum resources, if a constellation system is completed before other systems, and the subsequent system is not allowed to use the occupied frequency resources, it will cause a great waste of satellite radio spectrum resources, and it will be extremely unfavorable to latecomers. Fairness; when multiple NGSO systems exist at the same time, it becomes a huge challenge to achieve compatible coexistence between systems: if satellites of different systems use the same spectrum resource to cover the same area, if the system-level design is not used to achieve spectrum awareness and avoidance , will inevitably interfere with each other and cannot carry out communication services normally
