PPP (Precise Point Positioning)

Precise Point Positioning (PPP) is a GPS-based technique that allows for highly accurate location measurements using a single receiver. It achieves this by applying advanced corrections for satellite clock errors, atmospheric effects, and other signals' inaccuracies, often using data from global networks of ground stations. Unlike traditional methods requiring multiple receivers or additional infrastructure, PPP delivers precise positioning (often within centimeters) with just one device, making it valuable for applications like surveying, navigation, and scientific research where high accuracy is essential.
