【摘要】 在分析GPS绝对定位误差产生原因的基础上,使用GPS模块记录移动台和基站的定位数据,测量时间从上午9点50分到10点,连续观测6 d.采用对移动站测得的数据求平均值,利用基站数据进行位置差分校正的方法,使绝对定位的误差减小,提高测量精度.在此基础上,利用位置差分的方法来修正行车航迹,纠正行驶路线,从而获得了可靠性较高并且符合实际情况的航迹图.更多还原

【Abstract】 This paper analyzes the reasons of the errors of GPS static absolute positioning.This method is using GPS model to record the data of GPS from mobile stations and static stations in six days.In every day the time for location is from 9:50 to 10 am.Then through seeking the average of every group of values of mobile station and using the position difference by the values of static position to emend the value of mobile station,the error of the value is reduced,and thus the value become more precise.更多还原
