| The Origin blue i utilises GPS (Global Positioning System) satellite positioning technology. The GPS coordinates of every fixed installation speed trap, of every variety, are stored in a memory chip within each device. |
The 12 channel GPS receiver within each device will lock onto at least three satellites at any one time, out of a total of eleven satellites orbiting the Earth in the Northern Hemisphere which are owned by the American Government. By using triangulation calculations, the position of a vehicle equipped with the device will be known to an accuracy of under five metres, and this position is continually tracked and updated as the user moves around the road network. | At the same time, the position of the user on the road network will be continually compared with the database of GPS coordinates of every fixed speed trap installation contained in the memory inside each device. When the user approaches a speed trap, a synthesised voice, on-screen message, flashing LEDs and a series of beeps will alert him to the fact that he is approaching a speed trap. The distance at which the alert will trigger is user definable, in the range of 200m to 2000m. | | Origin Technologies is keeping the master database of speed trap GPS positions up to date at all times, with new speed trap locations being derived from a number of sources. Using the supplied modem it will be possible for the user to download at any time via a standard telephone line the latest, most up to date speed trap information, at a cost of £50 per annum. |
