摘要：

【目的】近年来,精密单点定位（Precise Point Positioning, PPP）技术凭借其高精度、灵活性等特点已逐渐广泛应用于精密导航定位等应用中。但随着大众用户对导航定位需求的不断增加,硬件成本已成为制约高精度卫星导航定位在大众用户中广泛使用的主要因素之一。【方法】因此本文提出了一种基于低成本单频接收机的多模非组合单频PPP模型,并基于实测单频数据进行了数据质量分析与动态定位验证。【结果】结果表明：基于本文提出的多模非组合单频PPP模型水平精度为0.1m左右,高程精度为0.3m左右。【结论】可满足大众用户车道级导航定位需求。

Abstract:

[Objective] Nowadays, precise point positioning (PPP) has been widely applied in precise navigation thanks to its high precision and flexibility. The hardware cost has become one of the main factors which limits the widespread application of high precision satellite navigation by mass users. [Methods] Thus a multi-GNSS uncombined single-frequency PPP model based on low-cost single-frequency receivers is proposed in this paper. We validate the performance of the single-frequency PPP model by real single-frequency observations. [Results] The results show that the horizontal positioning accuracy is 0.1 m and the vertical positioning accuracy is 0.3 m. [Conclusions] The new model proposed in this work can meet the need for lane-level navigation for mass users.
