Using the GPS Function
The GPS Function
GPS (Global Positioning System) is a space-based satellite navigation system that
provides location and time information anywhere on the earth. It was developed by the
U.S. Department of Defense as a military system. When the GPS receiver acquires 3
or more signals (of about 30) GPS satellites orbiting at an altitude of about 20,000 km,
it can calculate and display its current position (latitude, longitude, and altitude) within a
tolerance of several meters. In addition, GPS can receive the exact time from the satellite
onboard atomic clock.
Activating the GPS Function
Activating the GPS function enables the transceiver to automatically obtain the internal
clock setting, and your location information setting from the GPS data.
The default setting is ON.
1. Press and hold the [ F
MENU
] key

touch [ APRS ]

[ 20 GPS POWER ].
2. Rotate the DIAL knob to select “ GPS ON ”.
3. Press the PTT switch to save the setting and return to normal operation.
When the GPS function is active, the power consumption increases by about 15 mA. As a
result, the battery life is reduced, as compared to when the GPS function is deactivated.
Displaying Position Information of Remote Stations in Digital Mode
With V/D mode of the C4FM digital, the GPS position information is transmitted simultaneously
with voice signals; therefore, the direction and position of the remote station can be displayed
in real-time even while communicating.
For details, see “ Real-Time Navigation Function ” (page 30)
• Even if the GPS function of your station is set to OFF, the position information of the
remote station can be displayed in V/D mode.
• When the GPS function is not active, the remote station cannot display the position
information for your station.
