GNSS receivers are an essential part of modern technological devices. Mobile phones, digital cameras, and car navigational systems are only some examples for tools using GNSS technology. These sensors can be used to support other tasks as well. A simple example is fleet management where the car navigation systems can provide data on the current position, intended target and selected route of the vehicles. However, utilizing data requires information on its quality, in this case on the positional accuracy of the sensors. This quality was checked for GNSS receivers in different mobile phones and a tracking device.
Tracking of vehicles is usually restricted to a navigational network. In many cases, several lines may be in parallel with small lateral distance, e.g., lanes on a street, parallel streets, or parallel rail tracks. In these cases, the lateral quality is of higher importance than the longitudinal quality. Thus we concentrated on this aspect of the quality.
