Global Positioning System (GPS)
If this feature is enabled, GPS data can be received from satellites when a GPS receiver is
attached to the serial port of the radio. GPS data can be viewed using P25, Conventional,
MultiNet, and SMARTNET/SmartZone Systems.
5.14.1 Viewing GPS Data
To use the GPS feature (on a properly configured radio):
1
Connect the cable from the GPS receiver to the Accessory Cable on the back of the
radio (see Figure 2.8).
2
Press the assigned GPS button (or select GPS from the menu). “NO SAT REC” will
display initially.
3
Wait until the GPS receiver acquires enough satellites to obtain a valid position fix.
Note
It may take up to 10 minutes, depending upon signal conditions, for the GPS receiver to
obtain a position fix. During this time “No Sat Rec” is displayed. Failure of data to
appear indicates that the receiver was unable to obtain a fix.
When the system acquires a fix, one of the following GPS data items will appear on the
display:
- Latitude (e.g., 40
o
55.32’N)
- Longitude (e.g., 90
o
23.41’W)
- Altitude in meters (e.g., 390.2)
- Speed (e.g., 55.5 MPH)
- Course Over Ground (e.g., COG 183.4
o

- Time (e.g., 14:23:15)
- Date (e.g., 26NOV2008)
- Number of satellites that the receiver is currently receiving

You can cycle through the data items by turning the Select knob.
