Precise Point Positioning using GPS
Precise Point Positioning (PPP) is a GPS technique that determines a receiver's exact location by analyzing signals from multiple satellites simultaneously. It uses advanced corrections for satellite clock errors, atmospheric conditions, and other factors, often obtained from global networks. This allows for very high accuracy—often within centimeters—without needing nearby reference stations. PPP is useful in applications like surveying, navigation, and scientific research, providing precise positioning anywhere in the world with a single receiver and standard GPS signals.
