Research and study on new potential EGNOS services for aviation

The European Commission is currently defining the roadmap for the long-term evolution of EGNOS, the European regional satellite-based augmentation system used to improve the performance of global navigation satellite systems (GNSS) for precision applications, including civil aviation.

Date : April 2018 – March 2019
Duration: 12 months
Client: European Commission

Project overview

The possibilities offered by the system are immense and its applications vast, which is why careful thought needs to be given to planning its possible future evolutions. When it comes to aviation, which future use of EGNOS services would allow significant gains in terms of performance, capacity and safety?

A recent study Egis undertook on behalf of the European Commission looked at answering this question. It took an initial look at the potential operational applications that future versions of EGNOS could support.

Egis consulted all stakeholders in the aviation sector in Europe, analysing and defining the reasons that would motivate EGNOS developments, determining the constraints and prerequisites and assessing the added value for end users.

Our missions

This consultation process enabled us to identify a set of applications that would benefit from EGNOS services:

  • the use of surveillance based on ADS-B (Automatic Dependent Surveillance-Broadcast) at airports equipped with A-SMGCS (Advanced Surface Movement Guidance & Control System) to provide even more accurate aircraft position data;
  • improved performance of approach procedures beyond CAT I based on GNSS and without the need for new infrastructure on the ground;
  • the use of a new altitude reference system based on geodetic altitude for enhanced accuracy of aircraft position and altitude without being affected by meteorological and environmental conditions.

This study opens up a wide range of possibilities for further analysis and evaluation of these potential uses and services.
