不同接收机天线相位中心改正模型对GPS/BDS精密定位的影响
Effect of phase center correction models of different receivers on GPS/BDS precision positioning
摘要
Abstract
In view of the difference of antenna phase center(APC)model and instrument manufacturer model of domestic ground receiver of different brands and models,relative positioning and precise single point positioning(PPP)methods are adopted respectively in this paper,based on the analysis of the difference of the estimated position caused by different APC correction models in GPS/BDS high precision positioning,the average difference value of the influence of different APC correction models of each antenna on the estimated position of the station is obtained.The experimental results show that different APC correction models have the same effect on the positioning accuracy of the station,but have little effect on the estimated position in the plane direction and the elevation direction.The influence of the same type of antenna on the different experimental area is consistent,and the influence of the same brand antenna on the estimated position of the station is similar,especially with the brand with the series of products its phase center closer to the impact.关键词
