Precise Point Positioning (PPP) is a global navigation satellite system (GNSS) positioning method that calculates very precise positions, with errors as small as a few centimeters under good conditions.

PPP is a positioning technique that removes or models GNSS errors to provide a high level of position accuracy from a single receiver. A PPP solution depends on a set of corrections generated from a network of global reference stations.

Precise point positioning (PPP) stands out as an optimal approach for providing centimeter-level error positioning using current and coming GNSS constellations.

Precise Point Positioning (PPP) is a global precise positioning service using all the available GNSS constellations. PPP requires the availability of precise reference satellite orbit and clock products using a network of GNSS reference stations distributed worldwide.

Mar 24, 2025 · Key to PPP is the use of precise satellite orbit and clock estimates derived from a global reference network, which can receive measurements from an entire GNSS constellation. Additionally, to maximize performance, remaining error sources are modeled or estimated.

PPP-AR enhances traditional PPP by resolving carrier phase ambiguities (Ambiguity Resolution, AR) to improve positioning accuracy. Traditional PPP solutions treat ambiguity as a float solution, while PPP-AR applies Uncalibrated Phase Delay (UPD) corrections to fix ambiguities as integer values, significantly improving convergence time and accuracy.

PPP is a positioning technique that removes or models GNSS system errors to provide a high level of position accuracy from a single receiver. A PPP solution depends on GNSS satellite clock and orbit corrections, generated from a network of global reference stations.

Precise point positioning (PPP) is a modeling and processing method that uses global navigation satellite system (GNSS) pseudorange and carrier‐phase observations, along with precise satellite orbit and clock products, for single‐receiver static or …

Apr 8, 2025 · Precise Point Positioning (PPP) relies on the availability of precise GNSS satellite orbits and clocks. This is fundamentally different from positioning with respect to a local base station or network with RTK.

PPP means Precise Point Positioning. It refers to the technology in which the server makes use of global or regional reference stations to make a real-time estimation of satellite orbit errors, clock errors, etc., and directly broadcast to the end user via satellite or over the internet.
