New EGNOS Safety of Life Assisted Service for Maritime Users

EGNOS, Europe’s regional satellite-based augmentation system (SBAS), is adding a new service to its repertoire: the EGNOS Safety of Life Assisted Service for Maritime Users (ESMAS). 

DGNSS, short for Differential Global Navigation Satellite System, is an enhancement to GNSS that was developed to correct errors and inaccuracies in the GNSS system and thus allow for more accurate positioning information.

Used to improve the performance of global navigation satellite systems like Galileo and GPS, EGNOS provides several navigation services to the aviation, maritime, rail, surveying and agriculture sectors, along with a range of land-based users.

The new ESMAS is in addition to the already available EGNOS Open Service, which is used by mass-market receivers and common user applications; the EGNOS Data Access Service (EDAS), which offers ground-based access to EGNOS data through the internet; and the Safety of Life Service (SoL), which is used for safety-critical aviation applications that require enhanced, guaranteed performance and an integrity warning system.

Unlike these other EGNOS services, which are delivered by ESSP under a contract with EUSPA, ESMAS will be delivered directly by EUSPA.

The EDAS and Maritime Website, contains real-time service performance, and information about the service’s historical performance, along with all relevant documentation (e.g., SDD, Service Notices, etc.). Users can also pose questions related to the service via the site’s Helpdesk contact form. For urgent issues, a 24/7 hotline is available.
