摘要
GPS精密单点定位技术是目前GPS研究领域的热点之一。文中先简要介绍了精密单点定位的数学模型、数据处理总体思路以及不同IGS产品对解算结果的影响;然后从静态和地面车辆动态两种模式分别介绍了精密单点定位精度测试过程与数据分析结果。实验测试结果表明:精密单点定位可以达到厘米级的定位精度(WGS 84坐标),收敛速度一般为30 min之内。
PPP(precise point positioning) is one of the hotspots in GPS research field.The paper introduced its math model and data-processing scheme,described the effects of different IGS products on the solution results and presented the testing process and the data analysis result for PPP in static and dynamic modes.It was verified that this method of PPP could reach the precision of centimeter-level(in WGS-84 coordinate),and the convergence time is generally within 30 min.
