GPS/伪卫星组合选址优化的一种思路
An Optimization Model in Selecting Location of GPS/Pseudolites
摘要
Abstract
In order to improve positioning geometry strength and to increase the number of visible GPS satellites,Integration of GPS and pseudolites was used to improve the precision of positioning.The concept dilution of precision（DOP） was explained,and fundamental theories and corresponding formulas were illustrated.Based on the information of one mining area,the pseudolite’s effect on improving the precision of positioning is analyzed by Matlab,and build a three-dimensional model in term of independent variable of azimuth angel,elevation angel and observed epochs,in order to improve the efficiency of pseudolites locations.关键词
