The method involves determining a position of navigation device and determining several radio transmitters. The primary and secondary radio transmitters among radio transmitters are selected based on position of navigation device. The initial time period a...

The part has a front part (200) comprising a distance piece (204), and a front conductor plate i.e. thin plate, arranged behind the part and designed as a single-piece. A first printed circuit board section (101) is arranged at the part, and an incremental...

The method involves determining position of a vehicle (101) and determining the position related to a preferred lane by using the map data. The position related to a current lane, on which the vehicle travels, is determined by using an image recording unit...

The method involves determining a position (202) of a navigation device, and defining square-shaped regions (209-215) in which the position of the navigation device is arranged so that an area (200) of the region is smaller than an area of a base. Map data...

The method involves specifying an input data for calculation process, where another input data is specified for another calculation process by using a processing unit (201). The calculation process is executed by using the input data for the calculation pr...

The satellite-based navigation system has a route calculator, a Global positioning system-antenna, a location- and position estimation module for determining the current position, and receiving units which possess capacity for receiving radio signals and t...
