摘要
本文基于支持BDS系统和GPS系统的高精度OEM板卡进行嵌入式RTK算法设计,实现BDS单系统、GPS单系统RTK定位功能,并进行室外实地测试。测试结果表明,开阔空间静态零基线测量北斗系统水平精度亚毫米,垂直1mm;GPS系统三维统计精度均优于3mm.开阔空间静态10km基线测量GPS解算结果较好,水平误差小于1cm,垂直误差大部分小于3cm,统计误差水平4mm以内,垂直2cm以内;北斗双频解算三维误差大部分在4cm以内,统计精度水平优于1.5cm,垂直优于3.5cm.BDS系统动态RTK测量同实际路线符合良好,单历元中误差在6mm以内。
Using the high-accuracy OEM board,which contains of BDS and GPS system,this paper realized the embedded algorithm of RTK of BDS、GPS and BDS＋GPS.The test of outdoor proved that the accuracy of zero static baseline is sub-mm for the horizontal component and 1 mm for vertical component using BDS.The accuracy of GPS for 10 km static baseline,whose difference of horizontal component is smaller than 1cm and the vertical component is smaller than 3cm,is better than BDS,whose difference for three component is better than 4cm.The statistics accuracy of GPS for 10 km baseline is better than 4mm for horizontal component and better than 2cm for vertical component,and the BDS is better than 1.5cm for horizontal component and better than 3.5cm for vertical component.For kinematic baseline,the result of integration positioning is accordant to the real topography,and the standard deviation is better than 6mm.
