Digital GPS Speedometer

Hummingbird's GPS Speedometers provide a quick to install, vehicle-independent speed readout in vehicles that are not fitted with conventional speedometers.

Using data received from the Global Positioning Satellite network the GPS Speedometer calculates three-dimensional ground speed and displays it on a clear to read digital display.

This high technology solution eradicates the dependency on vehicle specific parameters, thereby reducing installation time and eradicating the need for periodic calibration.

Designed for harsh automotive environments, the module features 1 inch high, high-brightness green LED digits. Automatic contrast adjustment ensures that the driver is able to read the display in daylight and is not blinded at night.

The ability to track 12 satellites simultaneously, enhanced receiver sensitivity and active antenna result in fast time-to-first-velocity-calculation as well as the ability to operate in the harshest RF environments such as canyons and cities. Speed errors will occur in RF blackout zones such as tunnels; this is indicated to the driver through a flashing display.

Three-dimensional velocity calculations are accurate to 0.2km/h and pulse output rates are updated 4 times per second.

Hummingbird's GPS Speedometer can be supplied with the readout in kilometers per hour (Kph) or miles per hour (Mph).

A speed-dependent switch with high current relay output is available as an option. Both normally-open and normally-closed outputs are provided. Typical applications for the speed switch would be driver over-speed warning or motion detection. Activation speed is user settable.

A maximum-speed recall-switch is available on all models. Press and hold the recall switch for 3 seconds to reset to 0.

Hummingbird's GPS Speedometer is supplied in a rugged ABS plastic enclosure with a lexan facia. A fully adjustable dashboard mount stand allows for correct driver orientation. Antenna connection for the active antenna is provided through a gold-plated threaded SMA connector. The active antenna is available in two options:

• magnetic mount, suitable for mounting in the interior of the vehicle, for example under the dashboard or rear window sill.
• bulkhead mount, suitable for exterior mount, for example on the roof of the cab.

Power to the unit and switch outputs are provided through six colour-coded wires.

For optimum performance the antenna should be mounted horizontally and upright, and should have a clear view of the sky.
