Precise Point Positioning

CSRS-PPP service upgrade from version 4 to version 5

On Wednesday, 14 May 2025, the Canadian Geodetic Survey of Natural Resources Canada updated the Canadian Spatial Reference System Precise Point Positioning (CSRS-PPP) service. This CSRS-PPP update includes, for the first time, support for Galileo PPP with ambiguity resolution (Galileo PPP-AR) for E1/E5a observations collected on or after 27 November 2022 when processed with either the Rapid or Final products. Submissions processed with the Ultra-rapid products will continue to support only GPS and GLONASS observations. At the same time, there will also be minor updates to some CSRS-PPP outputs.
