Performance Analysis of BDS-3 Multi-Frequency PPP Model
Abstract In order to verify the positioning performance of the new triple-frequency PPP model of the BDS-3 system, we derive the new triple-frequency PPP model based on the original observation equation and derive the pseudorange deviation correction again in the model. Using BDS-3 data observed by 14 MGEX stations, we compare and analyze the static and dynamic positioning performances of three triple-frequency PPP models and two traditional dual-frequency uncombined models. Experimental results show that the new triple-frequency PPP model can improve convergence time and positioning accuracy, and the TDF model has the greatest improvement effect.
