28Using the GPS FunctionThe GPS FunctionGPS (Global Positioning System) is a space-based satellite navigation system that pro-vides 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 moresignals (of about 30) GPS satellites orbiting at an altitude of about 20,000 km, it can cal-culate and display its current position (latitude, longitude, and altitude) within a toleranceof several meters. In addition, GPS can receive the exact time from the satellite onboardatomic clock.Activating the GPS FunctionActivating the GPS function enables the transceiver to automatically obtain the internalclock setting, and your location information setting from the GPS data.The default setting is ON.1. Press and hold the [DISP] 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 18 mA. As aresult, the battery life is reduced, as compared to when the GPS function is deactivated.Displaying Position Information of Remote Stations in Digital ModeWith V/D mode of the C4FM digital, the GPS position information is transmitted simulta-neously with voice signals; therefore, the direction and position of the remote station canbe displayed in real-time even while communicating.For details, see “Real-Time Navigation Function” (page 32)• Even if the GPS function of your station is set to OFF, the position information of theremote station can be displayed in V/D mode.• When the GPS function is not active, the remote station cannot display the positioninformation for your station.
