摘要
本文简述了提高GPS定位精度和系统性能的两条主要技术途径(差分GPS、GPS/INS组合)的特点和问题;提出了差分GPS/惯性导航组合系统方案;研究了组合系统的卡尔曼滤波器的设计问题,并作了计算机模拟仿真。仿真结果表明,差分GPS/惯性导航组合系统可以达到1~2米的实时定位精度。
This paper describes the characters and shortcomings of the two main technical ways to improve the precision and performance of GPS brifly (that is, DGPS and GPS/INS). A scheme for integrating DGPS and INS has been proposed. The paper studied the design of kalman filter for this kind of system and a computer simulation was made. The result indicates that DGPS/INS integrated system can provide a R. T. positioning precision of 1~2 meters.
