PPP integrity for advanced applications, including field trials with Galileo, geodetic and low-cost receivers, and a preliminary safety analysis

Abstract:

Precise Point Positioning (PPP) is a consolidated high precision positioning technique providing centimetre-level error. PPP processes dual-frequency pseudorange and carrier-phase measurements from a single user receiver, using detailed physical models and precise GNSS orbit & clock products calculated beforehand, but it can also work with single-frequency receivers, significantly enhancing the receiver PVT solutions, in either the double and in the single frequency cases. PPP provides absolute positioning as opposed to relative techniques such as RTK (Real Time Kinematics). PPP can be applied to both post-processing and real-time applications, provided that real-time input orbit and clock data are available. In the last years, we have been working in developing an integrity layer to be added to the PPP positioning solution, necessary for the provision of certain critical applications. One of the main …
