EGNOS High Accuracy Service Analysis

The objective of EGNOSHA was to determine under what conditions it would be beneficial to implement an EGNOS V3 high accuracy service in 2020-2035 for various user sectors.

Background

EGNOS is the European SBAS and augments the GPS L1 C/A civilian signal by providing corrections and integrity information for positioning and navigation applications over Europe. The next generation of EGNOS, EGNOS V3, will augment GPS and Galileo constellations in the L1 and L5 bands and will extend the service area to the entire landmasses of EU member states.

The European Commission is defining the long-term evolution of the EGNOS programme beyond the current EGNOS Service Release V3. One potential evolution could lead to the provision of an EGNOS V3 High Accuracy service over Europe. 

Project objectives

EGNOSHA project analysed the benefits of a potential EGNOS V3 (i.e. based on Dual Frequency Multi-constellation (DFMC) capability) High Accuracy service able to provide accurate GNSS orbit and clock corrections, atmospheric corrections and integrity alerts to support emerging applications in various sectors (agriculture, road, rail, maritime, etc.).
