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.
