The Hummingbird GPS Speedometer is an easy to install digital speedometer including an internal antenna. It is ideal for vehicles not fitted with conventional speedometers such as tractors, rollers and graders.
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.
Powerful Performance
Designed for harsh automotive environments, the module features 1 inch high, high brightness red 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 20 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 speed readings are updated 10 times per second.
Hummingbird's Digital GPS Speedometer can be user configured to work in kilometers per hour, miles per hour, knots or meters per minute.
A relay can be set to close when the speed exceeds a user specified set-point. Typical applications for the speed switch would be driver over-speed warning or motion detection. Activation speed is set via a dip switch internal to the device and cannot be changed by the operator. The maximum speed can be set to be
between 0 and 999 or between 0 and 99.9. The more precise setting is suitable for slow vehicles like tractors.
