GNSS augmentation (original) (raw)
Ein Satellite Based Augmentation System (SBAS; deutsch Satellitenbasiertes Ergänzungssystem) ist ein Satellitennavigationssystem, das vorhandene andere Satellitennavigationssysteme wie z. B. GPS oder allgemein GNSS, unterstützt. SBAS liefert zusätzliche Informationen, die von geosynchronen (meistens geostationären) Satelliten ausgestrahlt werden und Zuverlässigkeit, Genauigkeit und Verfügbarkeit der Positionsbestimmung erhöhen.

(de) Augmentation of a global navigation satellite system (GNSS) is a method of improving the navigation system's attributes, such as precision, reliability, and availability, through the integration of external information into the calculation process. There are many such systems in place, and they are generally named or described based on how the GNSS sensor receives the external information. Some systems transmit additional information about sources of error (such as clock drift, ephemeris, or ionospheric delay), others provide direct measurements of how much the signal was off in the past, while a third group provides additional vehicle information to be integrated in the calculation process. (en) SBAS, abreviatura inglesa de Satellite Based Augmentation System (Sistema de Aumentación Basado en Satélites), es un sistema de corrección de las señales que los Sistemas Globales de Navegación por Satélite (GNSS) transmiten al receptor GPS del usuario. Los sistemas SBAS mejoran el posicionamiento horizontal y vertical del receptor y dan información sobre la calidad de las señales. Aunque inicialmente fue desarrollado para dar una precisión mayor a la navegación aérea, cada vez se está generalizando más su uso en otro tipo de actividades que requieren de un uso sensible de la señal GPS. Actualmente están desarrollados o en fase de implementación los siguientes sistemas SBAS: * WAAS (Wide Area Augmentation System), gestionado por el Departamento de Defensa de los Estados Unidos. * EGNOS (European Geostationary Navigation Overlay Service), administrado por la Agencia de la Unión Europea para el Programa Espacial. * (Wide Area GPS Enhancement), que transmite más precisión en los datos de efemérides y reloj de los satélites destinado a uso militar. * MSAS (Multi-Functional Satellite Augmentation System), operado por Japón. * , gestionado por la empresa John Deere. * QZSS (Quasi-Zenith Satellite System), propuesto por Japón. * GAGAN (GPS and GEO Augmented Navigation), planeado por la India. (es) 항공항법정보시스템(Satellite Based Augmentation System, SBAS)은 추가적인 위성방송 메시지를 사용해서 광범위한 지역 또는 지역적인 보강을 지원하는 시스템이다. 이런 시스템은 보통 정확하게 측량된 지점에 위치한 여러개의 지상관측소로 구성된다. 지상관측소는 한개 또는 그 이상의 GNSS위성, 위성신호, 또는 사용자들에 의해 수신된 신호에 영향을 줄 수도 있는 다른 환경적인 인자를 측정한다. 이런 측정값을 사용해서 정보메시지가 생성되고 최종 사용자를 위한 한개 또는 그 이상의 방송위성에 보내진다. SBAS 설계 및 실행은 다를수 있지만, SBAS라는 용어는 이런 위성기반보강시스템을 말한다. 국제민간항공기구(ICAO)는 SBAS는 특별한 미국의 (광역오차보정시스템)의 설계와 부합하는 메시지 포맷과 주파수를 전송해야만 한다고 규정하고 있다 GNSS(범지구위성항법시스템)의 보강은 외부정보를 계산과정에 통합함으로써 항법시스템의 정확도, 신뢰도, 가용성과 같은 특성을 개선하기위한 방법 중 하나이다. 현재 이와같은 많은 시스템이 전 세계에 존재있으며 통상 GNSS센서가 외부 정보를 수신하는 방법에 따라서 이름을 부른다. 몇몇 시스템은 오차 원인에 대한 추가적인 정보(시계 드리프트, 천체력(ephemeris), 전리층지연)를 전송한다. 어떤 시스템은 위성신호가 과거에 얼마나 차이가 나는지 직접적인 관측을 제공하는 반면에, 계산과정에 통합될 수 있는 추가적인 차량의 정보를 제공하는 시스템도 있다. 미국은 세계최초의 SBAS인 WAAS(Wide Area Augmentation System)를 운용 중이다.

GNSS augmentation) — методы улучшения характеристик работы навигационной системы, такие, как точность, надежность и доступность, через интеграцию внешних данных в процессе расчета. Применяемое сокращение DGPS (рус. ДГНСС — дифференциальные глобальные навигационные спутниковые системы). Для повышения точности позиционирования навигационной аппаратуры ГНСС на земной поверхности или в околоземном пространстве. Суть большинства методов дифференциальной коррекции заключается в учете навигационной аппаратурой различного рода поправок, получаемых из альтернативных источников. Для различного рода применений источниками корректирующей информации являются УССИ (унифицированные станции сбора измерений), опорные координаты которых известны с высокой точностью. Как правило методы дифференциальной коррекции обеспечивают поправками ограниченную территорию Земли. Каналы доставки данных дифференциальной коррекции могут быть различными, традиционно это УКВ, сотовая и спутниковая связь. (ru) |
