Abstract:	The performance of real-time single frequency GPS Precise Point Positioning is demonstrated in terms of position accuracy, with the application of lane-identification for road-traffic in mind. This Precise Point Positioning technique relies on predicted satellite orbits, predicted Global Ionospheric Maps, and in particular on real-time satellite clock estimates, which are obtained from the RETICLE system of the German Space Operations Center (GSOC) / German Aerospace Center (DLR). A kinematic experiment was carried out, under true operational circumstances, with a car on the motorway between Rotterdam and The Hague in the Netherlands, employing a range of different GPS-equipment. The test demonstrates that the requirement of a 95% horizontal position component error smaller than 1.75 m for lane-identification is easily met with high-end and middle-class equipment, and most of the time also with lower end equipment (u-blox) with a patch antenna. With real-time Precise Point Positioning employing high-end and middle-class equipment, using solely single frequency measurements (on L1), 95% errors in the horizontal position components can get as low as 0.3-0.4 m.
