中文摘要:
      近年来,GPS技术和嵌入式技术在导航、定位、测量等领域都有良好的应用。为了对比分析3种常用的定位算法(最小二乘法、加权最小二乘法、卡尔曼滤波)的性能优缺点,针对不同的接收机以及考虑到性能、成本、运算效率、稳定性等多方面问题,设计了一套基于高性能ARM(STM32F429IGT6)的GPS定位仿真系统,实验分别采用两种不同性能的GPS接收机(NEO M8T和LEA 6T),实验运行结果表明,3种定位算法均能使GPS定位精度提高,但基于不同性能的接收机,其优化性能的程度是不一样的。该研究为工程实现中定位算法的选择提供有效的参考价值,同时基于高性能ARM的GPS定位系统为今后做差分定位,载波相位测姿以及组合导航等前沿技术研究提供良好的硬件和软件基础,在卫星导航定位领域中具有重要意义。
英文摘要:
      In recent years, GPS technology and embedded technology have a good application in navigation, positioning, measurement and other fields. In order to research and analyze the performance of three kinds of common positioning algorithms (least square method, weighted least square method and kalman filter), for different receivers and considering the performance, cost, operation efficiency, stability, and other aspects of the problems, this paper designs a GPS positioning system based high performance ARM. The experiment uses two different kinds of receivers(NEO M8T,LEA 6T). The practical operation results show that the three filtering algorithms can improve the positioning accuracy of GPS, but it has different degrees of optimization performance on the receiver with different performance. This study provides an effective reference value for selection of location algorithm in engineering implementation, at the same time, GPS positioning system with high performance provides a good base of hardware and software for differential positioning technology, carrier phase measurement, integrated navigation and other cutting edge technology research, and has important significance in the field of satellite navigation and positioning.
