This section includes a list of resources related to GNSS data that you might find useful, should you require further information.


term definition
broadcast ephemeris is the set of data delivered by the GNSS satellite such as satellite orbits and clocks that are required to compute the position
convergence time time that the navigation filter needs to reach a target accuracy in the position solution
formal error error estimate of the navigation filter
GNSS raw measurements The set of measurements (pseudorange and carrier phase) generated by a GNSS receiver, used to compute the navigation solution
navigation filter is the mathematical engine that implements a given strategy in order to estimate the

We'd rather have you using our service to compute position, but should you want to explore other services, here there is a list of them, that perform PPP, in case you want to try them out:
