On course for accuracy

摘要

A UK team plans to develop more accurate satellite location technology that could improve SatNav systems and help future road charging schemes operate efficiently. Researchers at Loughborough University are investigating map-matching algorithms that integrate locational satellite data with the spatial road network data to identify the physical position of the vehicle on the road in a variety of environments. They will focus particularly on algorithms for dense urban areas. 'A navigation device like a TomTom normally receives latitude and longitude data from a satellite, which is then superimposed on to an electronic map data inside it,' said Dr Mohammed Quddus at Loughborough.
