Fault-Free Integrity Analysis of Mega-Constellation-Augmented GNSS [PDF]
ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2019 In this paper, we evaluate the potential of mega-constellation-augmented GNSS (GNSS-MC) to provide fault-free high-integrity positioning in both open sky and urban areas. We derive a method to integrate dual-frequency carrier-phase ranging measurements from GNSS at medium Earth orbit (MEO), and mega-constellations at low Earth orbit (LEO) to achieve ...
