摘要：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 GNSStechnology. These sensors can be used to support other tasks as well. A simple example isfleet management where the car navigation systems can provide data on the current position,intended target and selected route of the vehicles. However, utilizing data requiresinformation on its quality, in this case on the positional accuracy of the sensors. Thisquality 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, severallines may be in parallel with small lateral distance, e.g., lanes on a street, parallel streets, orparallel rail tracks. In these cases, the lateral quality is of higher importance than thelongitudinal quality. Thus we concentrated on this aspect of the quality.
