Research on the Station Layout Method of Ground‐Based Pseudolite Positioning System Based on NSGA‐II Algorithm

Abstract

Given the problem that the existing method of station distributing the pseudosatellite system cannot ensure both its coverage and position in a situation of signal occlusion, it proposed a new stationary layout method with an elite strategy for a ground-based pseudosatellite positioning system based on the elite strategy of the nondominant genetic rankings (NSGA-II). The geometrical design of the pseudosatellite system is calculated by visual domain analysis and precision factors for the signal coverage age and base station. To optimize the algorithm, the NSGA-II algorithm is used. An earth pseudosatellite positioning system method of stationary distribution is obtained that simultaneously optimizes signal coverage and positioning accuracy. The algorithm is better distributed and has a certain superintendence compared with the traditional genetic algorithm.

Pseudolites to Support Location Services in Smart Cities: Review and Prospects

“…Moreover, the pseudolite constellation can be made more reasonable by testing the positioning accuracy of different locations of the receiver [130]. The geometric design of the pseudolite system can be determined via visual domain analysis and signal coverage time and base station accuracy factors [131].…”

A Layout Method of Space-Based Pseudolite System Based on GDOP Geometry

“…In addition, some scholars have applied the optimization algorithm to the optimal layout design of pseudolites, such as [12], where the linear decreasing weight particle swarm algorithm is used to optimize the deployment. Moreover, sparse A* algorithm [13], genetic algorithm [14]- [17], particle swarm optimization [18] and NSGA-II [19], [20] can be used to optimize pseudolite deployment. The pseudolite deployment scheme based on the optimization algorithm can often obtain a satisfactory result for the user, but it also has a common defect, that is, it takes a long time to obtain the results, which will limit the maneuverability of the space-based pseudolite platforms.…”
