European EGNOS system remains stable as GPS falters

European EGNOS system remains stable as GPS falters

As users of the United States GPS system experienced timing issues on 26 January after a number of satellites broadcast incorrect coordinated universal time (UTC) correction parameters, the European system EGNOS remained stable and properly synchronised to UTC.

According to the US Air Force anomaly report, the coordinated universal time message that was transmitted was off by 13 microseconds. EGNOS, which serves as an augmentation system to GPS, remained stable and properly synchronised to UTC, proving the importance of having a backup system.

Time information from EGNOS can be received via broadcast geostationary satellite signals or the EGNOS Data Access Service (EDAS), which allows users to access data online in real time.

EGNOS offers a protected global navigation satellite system (GNSS) timing service to all satellite-based augmentation system (SBAS) users, across all application domains. This includes aviation, rail, maritime, surveying, agriculture, location-based services and more.
