中文摘要：
本文研究建立了电离层参数估计的单频精密单点定位的数学模型,并综合考虑各项误差模型改正,运用卡尔曼滤波算法,开发了单频精密单点定位程序,最后利用实测数据进行实验。实验结果表明：静态平面、高程方向精度均优于0.15m,动态精度优于0.3m。
英文摘要：
An optimal mathematic model of single-frequency precise point positioning was built based on the estimation of ionosphere parameter in the paper.Then after considering all the observation error corrections,the author developed a calculating procedures of single-frequency precise point positioning via Kalman Filtering method.And experiments were done by the real data at last.The results showed that the accuracies about horizontal position and vertical position were both superior to 0.15m,and the dynamic accuracy was superior to 0.3 m.
