伪卫星独立组网布站优化设计
Optimization Design for the Iayout of Pseudolite-Alone Navigation Service
摘要
Abstract
In order to solve the problem that the pseudolites layout design requires large amount of computation,a practical scheme which takes the influence of the service area's terrain into account was designed in this paper.Using the point by point extrapolation method,the repeating calculation of the intersection points in DEM visible range analysis could be avoided.Using partition searching method based on the optimizing basis configuration,lots of useless calculation points could be eliminated.And the calculated result shows that the calculation amount can reduce to 8.43×10-7％ of the origin using the partition searching algorithm combined with the pyramid strategy.关键词
