WARPS is a peripheral device for mobile radios which transmits vehicle identity, GPS position and status when the radio microphone (Press To Talk) button is released, or when polled from a fixed base station.
WARPS avoids the use of standard data-transmission protocols, and uses a unique patent-pending solution to enable data transmission without interference over voice channels.
Physical Description of WARPS Positioning System WARPS is housed in a small rugged metal box (dimensions 156 x 102 x 45mm) with a base mounting plate (198 x 99mm) with holes allowing fixation where desired.
The WARPS unit connects to the mobile radio through the radio's auxiliary connector and by cable to a roof-mounted GPS antenna.
WARPS transmitted data integrates with commercially available mapping software to display all vehicles on a PC screen - as colour-coded pictograms or labels with vehicle ID and status. WARPS data can be simultaneously displayed across all networked computers.
