EDGAR (EGNSS DFMC for GBAS bAsed opeRations) Project aims at  contributing towards the development of an improved, more liable, 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. Being GBAS an enabler of enhance approach and optimised  descent operations permits the reduction of noise footprints, fuel  consumption and emissions, thus contributing to greener flights.  Moreover, this project pursues to contribute to the goal of an early  Dual-Frequency Multi-Constellation, or DFMC, GBAS adoption that allows  facing ILS CAT III rationalization thanks to the increased robustness  and thus rendering benefits to the aviation community. Therefore, the  application of GBAS alongside EGNSS will technically improve the current system and will have a positive impact on the economy and society. Hence, the main objectives of this proposal are: to further develop and  validate the GBAS DFMC solution so as to modernise and improve air  operations, with emphasis on providing safety, availability, and  robustness in all situations, including during challenging to  ionospheric conditions; to analyse the distinguishing features of  Single-Frequency Multi-Constellation, or SFMC, GBAS brought by the  addition of Galileo; and to facilitate CAT II service to GAST C airborne users based on a GAST D ground station with EGNSS integration (GAST C  and D correspond to standardized single-frequency single-constellation  equipment able to provide CAT I and III performances respectively).
