Precise Point Positioning with Kepler [PDF]
2019 IEEE 90th Vehicular Technology Conference (VTC2019-Fall), 2019 Precise Point Positioning (PPP) enables an absolute positioning with centimeter-level accuracy without the need of raw measurements from a reference station. However, today's GPS L1/ L2-based PPP solutions typically need more than 30 minutes to converge.
