To evaluate their performance, convergence time and accuracy of solutions are compared to Trimble NetR9, a survey-grade receiver. Post-processed PPP solutions of ZED-F9P were computed using RTKLIB and real-time PPP was provided by the MSJ-3008-GM4-QZS. Results showed ZED-F9P achieved an RMS of 5.28 cm, 2.89 cm, and 9.55 cm in East, North, and Up directions. This means ZED-F9P can be used in applications requiring below 10 cm accuracy even without base station. MSJ-3008-GM4-QZS obtained an RMS of 10.45 cm, 6.27 cm, and 27.56 cm in the same directions. Unlike ZED-F9P, it achieved above 10 cm accuracy in North and Up directions which is due to large errors from cycle slips and jumps in obse...
