В таких сферах, как, например, гражданская авиация, где критическую роль играет безопасность, применяются алгоритмы автономного контроля целостности (Receiver Autonomous Integrity Monitoring – RAIM) навигационного поля на этапах полета на эшелоне и неточного захода на посадку. Для повышения качества работы RAIM все чаще привлекаются глобальные навигационные спутниковые системы (ГНСС) на гражданских частотах. В настоящей статье анализируются данные наблюдений и эфемеридно-временная информация от 18 станций, задействованных в эксперименте по интегрированию ГНСС (Multi-GNSS Experiment – MGEX), для оценки эффективности RAIM при использовании многочастотных сигналов от нескольких ГНСС – в данном случае GPS, BDS и Galileo. Полученные результаты указывают на более высокую эффективность определения координат места и контроля целостности спутниковых данных при использовании комбинаций из нескольких ГНСС.

In critical safety domains like civil aviation, Receiver Autonomous Integrity Monitoring (RAIM) supports integrity services from oceanic routes to non-precision approaches (NPA). The expansion of GNSS (Global Navigation Satellite System) civil frequencies improves these services. To evaluate RAIM availability enhancements from Multi-Frequency Multi-System (MFMS) integration, observation data and broadcast ephemeris from 18 global Multi-GNSS Experiment (MGEX) stations were analyzed for GPS/BDS/Galileo (Global Positioning System/BeiDou Navigation Satellite System/Galileo Navigation Satellite System) combinations. The results indicate that MFMS integration significantly improves positioning and integrity performance compared to single-system operation.
