摘要
GPS利用卫星发射的无线电信号,通过计算卫星与GPS接收机之间的相对位置,进而确定出用户接收机在地球上的位置,可以为用户接收机提供实时的定位、测速和授时等服务。通过使用最小二乘法,对GPS的定位解算算法进行研究,设计了一种基于最小二乘法的GPS定位解算算法。通过使用模拟源对所设计的GPS定位算法进行了定位解算试验验证,将定位解算结果与设定的模拟接收机位置进行比较,试验结果表明,该定位解算算法具有良好的定位效果。
GPS uses the radio signals transmitted by satellites to determine the position of the user receiver on the earth by calculating the relative position between the satellite and the GPS receiver,and can provide real-time positioning,speed measurement and timing services for the user receiver.By using the least squares method,the GPS positioning solution algorithm is studied,and a GPS positioning solution algorithm based on the least squares method is designed in the paper.The designed GPS positioning algorithm is verified by the positioning solution test by using the simulated source,and the positioning solution result is compared with the set position of the simulated receiver.The test results show that the positioning solution algorithm has a good positioning effect.
