1. A positioning method of Precise Point Positioning-Real Time Kinematic PPP-RTK, comprising:
determining original observation data when a direct signal broadcasted by a multi-system navigation satellite and a Low Earth Orbit (LEO) constellation is detected via a receiver in a navigation apparatus, wherein the navigation apparatus is arranged at a user equipment;
receiving by the receiver navigation satellite augmentation information broadcasted by the LEO constellation, as well as an LEO satellite precision orbit and a precision clock bias;
performing Precise Point Positioning of the user equipment by the navigation apparatus using the navigation satellite augmentation information, the LEO satellite precision orbit and the precision clock bias, and the original observation data; or
when ground based augmentation comprehensive error correction information is received, performing ground based augmented Precise Point Positioning of the user equipment by the navigation apparatus using the navigation satellite augmentation information, the LEO satellite precision orbit and the precision clock bias, the original observation data and ground based augmentation comprehensive error correction information.
