Europe’s regional satellite-based augmentation system (SBAS), EGNOS, has received upgrades to advance the reliability of GNSS positioning information, according to EUSPA.

Historically, EGNOS has provided safe, uninterrupted satellite navigation services to aviators, and some maritime, railroad, and land-based users in Europe. This system upgrade includes extending its service area, adding advanced functionalities, and reinforcing dual-frequency and multi-constellation services.

The EGNOS V242B system upgrade will expand services outside of its service area and enhance availability to users. Additionally, the upgrade ensures aviator access to lifesaving services such as Localizer Performance with Vertical Guidance (LPV)-200. The upgrade also includes more advanced data processing functions to cater to increased issues with peak solar activity and ionospheric phenomena that interfere with EGNOS signals and services.

Dual-frequency and multi-constellation services were also improved in the EGNOS upgrade. The improvements revamped EGNOS Version 2, and reinforced EGNOS services before launching EGNOS Version 3 (V3).

EGNOS delivers two frequencies and has amplified Galileo signals, hence creating a multi-constellation capability. When EGNOS V3 is launched, it will offer additional services and enhance protection against cyberattacks, further advancing EGNOS’ safety-critical applications across Europe.
