摘要
[目的]旨在研究手机移动端GNSS定位精度的影响因素。[方法]以许昌学院为试验区域,采用Essential Phone PH-1和华为Mate 40pro移动智能手机,分别在晴、阴、雨3种不同天气下以及空旷、建筑密集、树林遮挡3种不同环境下,利用软件GPStest获取实测GNSS数据,并以RTK同步观测的数据作为参考值来进行对比分析,验证不同因素对手机移动端GNSS定位精度的影响。[结果](1)在相同条件下,华为Mate40 Pro比Essential Phone PH-1手机移动端的定位速度快,定位精度高。(2)天气条件显著影响手机定位精度,晴天定位精度最优,阴天次之,雨天最差。(3)不同环境场景下,空旷环境定位精度最高,建筑密集区次之,树林遮挡区定位精度最差。[结论]该研究结果有助于提高手机移动端GNSS定位精度,拓宽手机移动端的应用领域。
[Purposes]To study the factors affecting the GNSS positioning accuracy of mobile devices.[Methods]Xuchang University was used as the experimental area,using the Essential Phone PH-1 and Huawei Mate 40 Pro smartphones were employed in different environmental scenarios and three different weather conditions.The GNSS data were collected by the software GPStest,with synchronous RTK obser-vations used for comparative analysis to verify the influence of different factors on mobile phone GNSS positioning accuracy.[Findings]The results show that:Under the same conditions,the Huawei Mate40 Pro and Essential Phone PH-1 demonstrate faster positioning speed and higher accuracy.Weather condi-tions significantly affect the accuracy of mobile phone positioning,with the highest accuracy in clear weather,followed by overcast weather,and the worst accuracy in rainy weather.In different environmen-tal scenarios,the highest positioning accuracy is achieved in open environments,followed by densely built-up areas,and the worst positioning accuracy is achieved in areas with tree-obstructed environ-ments.[Conclusions]By analyzing the influencing factors of mobile GNSS positioning accuracy,we can not only improve the positioning accuracy of mobile GNSS,but also expand the application scope of mo-bile phone.
