The MUGG project – multi-mode Global Positioning System (GPS) and Galileo
project – was initiated by the European Global Navigation Satellite System
Agency (GSA) to develop an aviation Satellite-based Augmentation System (SBAS)
dual-frequency multi-constellation (DFMC) receiver, representative of the
next-generation dual-frequency multi-constellation Global Navigation Satellite
System (GNSS) aviation receivers.
Led by Collins Aerospace in collaboration with Pildo Labs, the MUGG project
actively supports future civil aviation GNSS receivers standardization and
certification. Support is implemented through a prototype of the latest EUROCAE
ED-259 – minimum operational performance standards (MOPS) for Galileo/GPS/SBAS
airborne equipment – and in-flight demonstration of the enhanced capabilities.
DFMC SBAS & the benefits for future aviation receivers
GNSS evolution with an increased number of satellites and new signals,
available due to DFMC, enables the GNSS navigation computation to have improved
accuracy, integrity and availability. These efficiencies increase the detection
and mitigation capability of the GNSS with regards to radio frequency,
ionospheric interference and multipath. As a result, the GNSS improves
navigation capabilities worldwide.
