EDGAR – An EU initiative for more efficient and sustainable air traffic

EGNSS DFMC for GBAS based operations (EDGAR) is an initiative aimed at contributing towards the development of an improved, more reliable, and accurate GBAS solution that responds, on the one hand, to the increasing demand for enhanced approach and all-weather operations in the ever-growing volume of air operations; and on the other hand, to sustainability requirements towards the compliance with EU Green Deal objectives.

The project is funded by the HORIZON-EUSPA-2022-SPACE-02-51, within the call "Strategic autonomy in developing, deploying and using global space-based infrastructures, services, applications and data"

Addressing Aviation Challenges

Despite recent challenges faced by the aviation industry, including the impact of COVID-19, there's a steady recovery underway. As demand continues to grow, airports must embrace efficient technologies and digitalization to meet evolving needs. EDGAR leverages European space infrastructures like EGNSS to enhance air operations, benefiting all stakeholders, including passengers.

Moreover, this project pursues to contribute to the goal of an early Dual-Frequency Multi-Constellation, or DFMC, GBAS solution that might support more stringent operations and increased robustness, thus rendering benefits to the aviation community.

Commitment to Sustainability

DFMC GBAS development contributes to industry commitments to achieve Net Zero emissions by 2050. Facilitating the introduction of advanced procedures, such as continuous descents and curved segments, EDGAR aims to contribute to the reduction in fuel consumption, emissions, and noise pollution around airports.

About GBAS

Ground-Based Augmentation System (GBAS) enhances Global Navigation Satellite Systems (GNSS) by providing precise corrections and integrity data to aircraft. This technology ensures accurate navigation solutions, particularly during critical phases like approach, landing, and take-off, even in adverse weather conditions.

Key Concepts

• DFMC GBAS: Dual-Frequency Multi-Constellation GBAS offers improved availability and robustness for Category II/III operations by leveraging dual-frequency techniques and multiple satellite constellations.
• GAST Evolution: We're driving the evolution of GBAS Approach Service Types (GAST) to support advanced landing operations, including CAT III, through convergence and standardization efforts at the ICAO level.

Collaborative Approach

EDGAR brings together a diverse consortium of stakeholders, including Air Navigation Service Providers, Research Centers, Universities, and Manufacturers. This collaboration ensures comprehensive development and adoption of cutting-edge GBAS solutions.
