With the aim to actively support and to accelerate the most widespread adoption of Galileo, Spaceopal announces the launch of NAVCAST, its GNSS Precise Point Positioning (PPP) service featuring high accuracy positioning enhancement for end users worldwide.

NAVCAST provides Galileo and GPS real time orbit and clock corrections based on an algorithm RETICLE (REal-TIme CLock Estimation), developed by the German Aerospace Centre (DLR e.V.).

Galileo and GPS observations, from more than 100 receivers of the world-wide IGS network, are used to estimate the current corrections which are broadcasted to registered users relaying on the standard NTRIP protocol.

NAVCAST corrections improve the user error down to the centimetre level, making it very attractive for a large number of applications.

Since today, it is possible to appraise the accuracy levels and convergence times achievable using NAVCAST (Galileo + GPS) corrections combined with a precise point positioning (PPP) engine, on the Spaceopal website. The underlying PPP engine (dual frequency, ionosphere free observations) estimates the local troposphere delays and fixes the carrier phase integer ambiguities.

NAVCAST can be considered as proof of concept and Spaceopal’s contribution to high accuracy GNSS services. NAVCAST corrections, which are today broadcasted over the Internet, could be in future via satellite constellation (i.e MEO satellites).
