Precise Point Positioning (PPP) is one of the existing techniques used to estimate user positions from GPS observations. PPP can provide centimeter-level positional accuracy anywhere in the world by utilizing a single receiver without the need of having nearby reference stations or a virtual network. With the advent of additional constellations (GLONASS, Galileo, BeiDou) the PPP technique continues to improve in achievable accuracies and availability. In this webinar, a brief overview of PPP will be discussed as will a comparison of similarities and differences between it and other GNSS positioning techniques. Several advantages of the use of PPP with and without multi-GNSS (MGNSS) observables will be presented including their current and future roles in land surveying. Finally, case studies highlighting practical applications of static and kinematic MGNSS PPP with be shown.
