摘要
为解决手持GPS量值溯源难题,本文从基线场观测墩固定间距直接比较法、观测墩坐标点法及室内便携式导航信号源法,对手持GPS导航及定位精度进行研究分析.实验证明:基线场观测墩固定间距比较法可将其控制在±5m以内;观测墩坐标点法受外界环境条件影响较大,造成测量精度(±10m以内)明显下降;室内便携式导航信号源法受外界环境条件影响较小,测量精度较高,且控制在±3m以内,满足精度等级±5m检测需求.
Abstract
In order to solve the problem of hand-held GPS magnitude traceability,this paper studies and analyzes the hand-held GPS navigation and positioning accuracy from the baseline field observation pier fixed distance di-rect comparison method,pier coordinate point method and indoor portable navigation signal source meth-od.Experimental results show that the fixed distance of observation pier in baseline field can be controlled within±5m.The coordinate point method of observation pier is greatly affected by the external environmental conditions,re-sulting in a significant decrease in measurement accuracy(within±10m).Indoor portable navigation signal source method is less affected by external environmental conditions,the measurement accuracy is high,and the control is within±3m,meeting the accuracy level of±5m detection requirements.
