Abstract

When the ground-based pseudolite positioning system is independent networking, distribution of base station is a multi-objective optimization problem to improve the system signal coverage and optimize the geometric layout of the base stations, thereby reduces the number of base stations and ensures positioning accuracy. This paper proposed the pseudolite base station distribution method based on the non-dominated sorting genetic algorithm(NSGA-Ⅱ) with elite strategy. The method used the visual domain analysis technology to calculate the system signal coverage and evaluate the geometric layout of the base stations by a weighted geometric precision factor of multi-matrix multiplication. Finally, the NSGA-Ⅱ algorithm searched the non-dominated optimal solution set of two optimization targets. The simulation of a mountainous area in Zhangjiajie shows only 28 base stations can ensure the system signal coverage reach 90%. At the same time, base station geometry is also good, the performance is better than the traditional genetic algorithm, it has certain guiding significance in practical engineering applications.
