Multi-Constellation T-RAIM: An Experimental Evaluation

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2017
Time-Receiver Autonomous Integrity Monitoring (T-RAIM) algorithms assess the reliability of the timing solution provided by a Global Navigation Satellite System (GNSS) timing receiver. Timing receivers process GNSS observables under the assumption that their antenna is static or that their position is known.

Multi-Constellation DGNSS - A Time to Revise Definitions

2020 European Navigation Conference (ENC), 2020
A paper describes a novel approach to computing DGNSS solution when multi-GNSS measurement observables are available. The approach is applicable to situations when not all the GNSS observables are accompanied with DGNSS corrections. A commonly used “classical” recommendation for such cases is to discard observables which do not have corrections ...

Satellite selection for multi-constellation

2008 IEEE/ION Position, Location and Navigation Symposium, 2008
There will be 70~90 navigation satellites operating at the same time when Glonass and Galileo reach full operation capability. As a result, the number of visible satellites can reach 30. Thus the positioning accuracy will be improved greatly. However, so many satellite measurements may burden the receiverpsilas processing element when to use them to ...
