What is GPS?
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. It receives signals from three or more
of about 30 GPS satellites flying at an altitude of about 20,000 km, and displays the
current position (latitude, longitude, and altitude) within a tolerance of several meters. In
addition, GPS can receive the exact time from the satellite’s onboard atomic clock.
Activating the GPS Function
To activate the GPS function, select [9 APROS] [23GPS POWER], and then select
[GPS ON] in the Set mode.
Tips
• Default: ON
When the GPS function on the transceiver is turned ON, internal clock settings and
position settings for your station are automatically obtained from the GPS data.

Tips
• Tip Information about the current positions of radio stations provided by GPS can be registered to
10 memory channels (P1 to P10). Registered position information can be used to set the position
of your station.
• When the GPS function is active, the power consumption increases by about 40 mA. As a result,
the battery life is reduced by about 20% compared to when the GPS function is deactivated.
• To use the GPS function during APRS operation, be sure to select [9 APRS] [24MY POSITION],
and then select [GPS] in the Set mode.
