Description
The Bird Compact GPS Sensor (GPS) is a NMEA complient global
positioning sensor (GPS). It is used with all SignalHawk models. It is
used to record geographic position information with a trace.
Note: Only SignalHawk firmware version 1.2.01302009 or
higher will support the GPS sensor. To get the latest firmware
for the SignalHawk, refer to the SignalHawk operators manual.
Connecting a Sensor
Connect the GPS to COM1 serial port located on the back of the
SignalHawk.

Using the GPS
Once connected, place the sensor in an elevated area. The sensor has a
magnetized base and is waterproof, so it may be placed outdoors on
the top of a car or the similar vehicle.
