Optimized Selection of Satellite Subsets for a Multi-Constellation GBAS [PDF]
The International Technical Meeting of the The Institute of Navigation, 2016 In the next generation of Ground Based Augmentation System (GBAS) corrections and integrity parameters for two frequencies and multiple constellations will be provided. However, the capacity of the VDB (VHF Data Broadcast) link providing those parameters to users is strongly limited.

Multi‐constellation ARAIM exploiting satellite motion
NAVIGATION, 2020 In this work, a new time-sequential positioning and fault detection method is developed for dual-frequency, multi-constellation Advanced Receiver Autonomous Integrity Monitoring (ARAIM). Unlike conventional “snapshot” ARAIM, sequential ARAIM exploits changes in satellite geometry at the cost of slightly higher computation and memory loads.

Multi-constellation GNSS scintillation at mid-latitudes [PDF]
2017 XXXIInd General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS), 2017 Radio wave scintillation can result in severe channel fading and random phase variations that can interfere with the performance of a radar, communication or GPS system. While it is well known that Ionospheric scintillation occurs within the high and low latitude regions, there has been minimal research done within the middle latitudes. However, recent
