Precise Point Positioning

Precise Point Positioning (PPP) is a satellite navigation technique that allows for accurate determination of a receiver's location using Global Navigation Satellite System (GNSS) signals. It is designed to provide users with centimeter-level positioning accuracy without the need for a reference station or local infrastructure. ### Key Features of PPP: 1. **Single Receiver**: Unlike traditional methods, like Differential GPS (DGPS), which require a network of ground stations, PPP utilizes a single GNSS receiver to compute positions.
