Detection of GNSS Horizontal Position Error Using 3D-Track Map
Original language description
Satellite-based augmentation systems (SBAS) such as WAAS in the USA, and EGNOS in Europe, are available and a new global satellite navigation system Galileo is being built by the European GNSS agency (GSA). The currently available SBAS systems were developed in order to satisfy aviation requirements. But the safety concept on railways is very different from the aviation safety concept. The railway safety concept in Europe is determined by means of the CENELEC standards (EN 50126, EN 50129, EN IEC 61508). The main problem is attainment of sufficient integrity of position solution. Satisfaction of safety integrity level 4 (SIL4) is necessary for railways. For the purpose of increasing the integrity of GNSS-based position determination we propose a new method of the detection of a GNSS horizontal position error based on the relation between vertical and horizontal position error. We investigated the relation between errors in the horizontal and vertical plane in real data measured by a GN
