基于GDCORS的北斗终端高精度定位算法实现及性能分析
Implementation and Performance Analysis of High-precision Positioning Algorithm for Beidou Terminal Based on GDCORS
摘要
Abstract
In order to enhance the social application scope and expand the service objects of GDCORS,we proposed a real-time high-precision positioning method based on time difference and Kalman filtering.We used this method to develop a high-precision positioning App,and devel-oped an external Beidou positioning module to match it.Then,we conducted static and dynamic positioning tests in Guangzhou using the re-al-time differential product data provided by GDCORS.The test results show that the proposed scheme achieves meter level Beidou pseudo range differential positioning based on mobile phone observation data,meter level Beidou carrier phase differential positioning based on single frequency external equipment,and centimeter level Beidou carrier phase differential positioning based on multi frequency external equipment,which has application and promotion value.关键词
