How does it work?
GPS Odometer Speed Sender provides a reliable calibration-free replacement for mechanical speed senders.
Using data received from the Global Positioning Satellite network, the GPS Speed Sender calculates three-dimensional ground speed and provides a pulsed output suitable for existing mechanical speed senders.
This high-technology solution eradicates the dependency on vehicle specific parameters thereby reducing installation time and eradicating the need for periodic calibration.
