Sending Global Positioning System (GPS) Data
If the radio is setup for operation with a GPS receiver (see Section 5.14), GPS data can be
sent to a properly configured repeater (digital conventional only).
Examples of GPS data sent are:
• Latitude (e.g., 40.55 N)
• Longitude (e.g., 90.41 W)
• Time (e.g., 14:23)
• Altitude in meters (e.g., 390.2)
• Course Over Ground (e.g., 183.4 DEG)
• Speed (e.g., 55 MPH)
• Date (e.g., 26NOV2008)
• Number of GPS satellites currently received
GPS data can be sent manually, automatically, or on system request, depending upon the
options enabled.

assigned GPS button is pressed and held.
6.16.2 Automatically Sending GPS Data
If the radio’s GPS “Auto Transmit” option is enabled, the radio will automatically send
GPS data at predetermined intervals.
