OSNMA

Galileo is the European Global Satellite Navigation Satellite System. Similarly to GPS, it offers an Open Service signal which allows all users to calculate position, velocity and time free-of-charge. Moreover, Galileo will provide a new features that allows to authenticate the data received from the satellite, contributing to increase the overall security of applications and services. This feature is called Open Service Navigation Message Authentication (OSNMA) and is soon becoming operational, free of charge, for every user to benefit from. OSNMA solves many of the current threats that poses at risk GNSS receivers in civil applications, and guarantees that the received Galileo Open Service navigation data is authentic... Validates the Navigation data (ephemeris, clock..) used by the GNSS receiver to compute the Position.
