GPS to Speed pulse interface This GPS interface is designed to provide a vehicle speed signal (VSS) to aftermarket equipment. The non-contact method of operation allows measurements of speed in applications where use of tradional speed sensors is not possible. Output is in digital pulse form with a frequency directly proportional to velocity. The velocity data is drived from Doppler measurements of GPS satellite carrier signals. This Doppler measurement ensures an accuracy of within 0.0625 Mph (0.1Km/h) when an open sky view is available. Operational status is indicated through a tri-colour LED. A recessed push button switch is housed on the rear of the unit to initiate a GPS cold start after installation. Applications:
The interface is also supplied with a GPS antenna. |
