Широкозонные системы спутниковой дифференциальной навигации
Приводится информация о широкозонных системам спутниковой дифференциальной навигации SBAS: WAAS (США), EGNOS (Европейский Союз) и MSAS (Япония), позволяющих повысить точность определения пространственных координат и геопозиционирования подвижных объектов
за счет поправок к эфемеридным данным и параметрам ионосферной модели. Приводится принципиальная схема функционирования системы SBAS и подробное описание видов и назначения корректирующей информации передаваемой с геостационарных спутников.
Wide Area Systems for Satellite Differential Navigation
Ye.I. Sunitsky (Moscow State University for Geodesy and Cartography)
#3, p 12
A brief introduction is given for the Satellite Based Augmentation Systems (SBAS), including the Wide Area Augmentation Systems (WAAS) in the USA, the European Geostationary Navigation Overlay Service (EGNOS) of the European Union and the Multifunctional Transport Satellite-bases Augmentation System (MSAS) of Japan. The SBAS systems make it possible to improve accuracy of the spatial coordinates determination as well as of the mobile objects geopositioning. This is due to the correction for the ephemeris data and the ionosphere’s model parameters. A principal scenario of the SBAS system operation is given. Types and designation of the correction data downlinked from the geostationary satellites are described in detail.
