EGNOS-SDK EnhancementsInformation on satellite origin of the location informationImplementation Details (Skyplot Feature)Based on the azimuth and the elevation information obtained from NORAD TLE (TwoLine Element Set) data the satellites are shown on the skyplot.The position of the satellite for a time in the past or future would be obtained byrequesting data from NORAD and determine current azimuth and elevation based on thisdata.Satellite information displayed: The number of GPS satellites used in GPS PVT, obtained by checking all thesatellites in view that have an elevation angle above ten degrees. The number of SBAS satellites in view The number of GPS satellites used in EGNOS PVT, obtained by checking all thesatellites in view that have an elevation angle above ten degrees and also thesatellites PRNs must be in the PRN mask and their UDREs have to be less than 14 Total number of satellites, indicating the number of GPS satellites in view The number of satellites not used, is obtained by getting all the satellites with anelevation less than ten degreesJune 2012 - EGNOS Software Development Kitpag. 15
