EGNOS SDK Development process - EGNOS Portal

EGNOS-SDK EnhancementsInformation on satellite origin of the location informationImplementation Details (Advanced Skyplot Feature)Information required: The Azimuth providing the direction at which the mobile device is pointed The elevation providing the smartphones screen angle relative to the horizon The azimuth and the elevation of the satellitesThe azimuth and elevation of device is converted to screen coordinates using thehorizontal and vertical angle of view of camera.The azimuth and elevation of satellites is converted to screen coordinates based on thecombination of the screen width and height and the screen coordinates of the azimuthand elevation of device. If the screen coordinates of the satellites are valid then thesatellite image is drawn on the screen. Due to computational requirements, the approachmight suffer modifications.The advanced skyplot view will also display the horizon, the geographic directions,arrows pointing to the EGNOS satellites and the historic path of the GPS satellites.June 2012 - EGNOS Software Development Kitpag. 16
