Detailed Description
This type is a QML representation of QGeoSatelliteInfo. The type is uncreatable from QML and can only be used when handling satellite updates from SatelliteSource.
This type contains the satelliteSystem, satelliteIdentifier and signalStrength read-only properties, and also optional attributes.
Use the hasAttribute method to check if the attribute exists or not, and the attribute method to get its value.
See also QGeoSatelliteInfo.
