Analysis of the influence of different weighted models on dynamicSPP positioning performance in urban complex environment

Abstract

Abstract: In complex urban environment, satellite positioning is seriously affected by non-line-of-sight signals (NLOS) due to the occlusion of buildings. The weighted model of random error of measured value is the key link of satellite positioning, which can reasonably distribute the role of each satellite in the calculation. Therefore, the weighted model is often used to alleviate the influence of NLOS signals on satellite positioning. This paper systematically summarizes and expounds the current mainstream weighted models, and compares and analyzes the influence of different weighting models on satellite dynamic single point positioning (SPP) in the complex urban environment. The experimental results show that all the weighted models can improve the positioning accuracy to a certain extent, and the comprehensive weighted model has the best performance.

Key words: complex urban environment, NLOS signal, weighted model, dynamic SPP
