Low earth orbit satellite constellation optimization design method for guaranteeing service quality

The invention discloses a low-orbit satellite constellation optimization design method capable of guaranteeing service quality, and belongs to the technical field of wireless communication. According to the method, the reliability, the effectiveness and the completeness of the satellite constellation are comprehensively considered, and the definition of the satellite constellation service quality is given. The error rate, the signal-to-noise ratio and the survivability are introduced to represent the reliability of the satellite constellation; introducing a coverage rate to represent the effectiveness of the satellite constellation; and representing the completeness of the users in the satellite constellation through the user matching degree. On this basis, setting a service quality threshold value and calculating a service quality value, setting the ratio of the total system capacity of the target area to the constellation construction cost as a target function, and iteratively optimizing the target function
