Publikováno v: Proceedings of the 30th International Technical Meeting of The Satellite Division of the Institute of Navigation (ION GNSS+ 2017).

The GNSS environment for civil aviation is evolving towards a Dual-Frequency Multi-Constellation (DFMC) scheme thanks to the deployment and modernization of multiple GNSS constellations (modernized GPS, Galileo, GLONASS, Beidou) broadcasting dual-fre
