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.
