Who we are European Satellite Service Provider

EGNOS (European Geostationary Navigation Overlay Service) augments the GPS L1 civilian signal by providing corrections information for both GPS space vehicles (Ephemeris, Clock) and ionosphere.

ESSP is a key actor within EGNOS because it:

• delivers, operates and maintains EGNOS augmentation services

• promotes EGNOS and its applications

• supports and interfaces with users

• monitors & analyses EGNOS performance

• supports in the development of EGNOS-based applications

Access free GPS augmentation What is a receiver?

• A GPS/SBAS receiver is a GPS receiver enhanced with special software enabling the receiver to lock onto the EGNOS satellites and apply the EGNOS corrections to the GPS signal.

• A NTRIP receiver; DGNSS and/or RTK receiver enhanced with special software enabling the receiver to retrieve GNSS data streams transmitted through the Ntrip protocol over the internet and apply a series of corrections to the GPS signal.
