  •  At present, only the BDS provides triple frequency observation data, and different linear combination models of observation data influence positioning accuracy and convergence speed of Precise Point Positioning (PPP). This paper deduced the optimal mathematical model of BDS three frequency ionosphere free combination PPP, and carried out experiment of BDS dualand triple frequency static PPP, using a large amount of measured data. The results show that, triple frequency static PPP obviously improves the positioning accuracy and convergence speed, compared to the BDS dualfrequency static PPP. BDS triple frequency static PPP can reach absolute positioning accuracy of 2~3 cm, with dualfrequency GPS PPP levels.
