Abstract:We use only one receiver to receive GNSS navigation signals and PPP-B2b augmentation signals simultaneously, and conduct 108 fast static experiments and 1 low-speed kinematic motor-guided rail experiment. The results show that: 1) For fast static PPP, the average convergence time of 97% of the samples is 34.6 min, and the horizontal/vertical accuracy after convergence is 5.9 cm and 9.7 cm, respectively; after restarting the receiver for 10/20/30 min, 78%/83%/86% of the horizontal accuracy is better than 10 cm, and 75%/84%/86% of the vertical accuracy better than 15 cm; 2) For the low dynamic guideway experiment, the RMS in the E/N/U direction reach 24.3/1.1/12.2 cm after 30 min of convergence time.
