An Algorithm of Inter Satellite Links Based on Ranging and Access

Abstract

It is a problem to build Inter Satellite Links so that Region Navigation System has optimal performance. Therefore, the article puts forward an algorithm, which synthesizes the time of satellites accessed and the distance of satellites. And then it carries out a simulation in navigation system to certify the superiority of the algorithm. The experimental result shows that the ISLs can effectively improve the performance of navigation system. And comparing with the traditional Minimum Distance Algorithm, the proposed algorithm has the same effect on improving the performance of navigation system and needs fewer times of changing links.
