Inside the CSRS-PPP Galileo Update: Accuracy Gains and What’s Next

Canada’s Precise Point Positioning (PPP) service has entered a new phase with the integration of Galileo, Europe’s satellite navigation system. This update strengthens the Canadian Geodetic Survey’s positioning infrastructure by adding more satellites, better geometry, and measurable gains in accuracy, particularly for short observation sessions where every minute matters.

The upgrade reflects years of evaluation, model testing, and international collaboration. With Galileo now included, users can achieve faster convergence, improved ambiguity resolution, and more robust results even in remote regions. The system also transitions to the IGS20 reference frame by default, ensuring alignment with the latest International GNSS Service standards while still delivering results in NAD83(CSRS) for practical field workflows.

In this technical explainer, Dr. Simon Banville, Senior Advisor for GNSS Products and Analysis at NRCan, shares insights on what Galileo brings to PPP, why the update matters, and how it fits into broader modernization efforts, including future plans for BeiDou, low-Earth-orbit satellites, and expanded real-time capabilities. The update also highlights a growing need for professionals who can bridge geodesy and programming, a recurring challenge across the Canadian geospatial community.
