10 GPS/GPS-A OPERATION10-18Transmitting GPS-A dataGPS-A mode is an operating mode supported with theD-PRS to transmit position data.In GPS-A operation, the following codes are transmit-ted to the PC connected to the IC-7100.GPS-A code is based on APRS® code.(APRS ® : Automatic Packet Reporting System).The L, R, C or D in theinstructions indicate thepart of the controller.L: Left sideR: Right sideC: Center bottomD: Display (Touch screen)Left RightCenterDisplayq Your own call signq w e r t ty u iw Unproto addresse Time stamp**h: “hhmmss”, z: “ddhhmm• The UTC time is used.• The data from the internal or external GPS is used.r Latitudet GPS-A symbol (Car)y Longitudeu Data extensioni GPS-A comment/AltitudeJA3YUA>API710,DSTAR�/002338h3437.38N/13534.29E>000/000/A=000000Who are you?About GPS-A dataGPS-A data is formatted as shown below.(e.g.)D Operating GPS-ATo transmit in GPS-A, follow the steps below, andfor more details, see the pages listed along with thesteps.1. “MY”(Your own call sign) programming (p. 7-2)2. Receing GPS data (p. 10-2)3. Set GPS TX MODE to GPS-A (p. 10-16)4. Transmitting GPS-A data setting (pp. 10-18 to10-22)Setting is completed.(Transmission is enabled in GPS-A)D D-PRSD-PRS is a function which simultaneously sends posi-tion data received from the internal or external GPS re-ceiver, using the slow speed data packet space, alongwith voice in the DV mode.In the analog format you can transmit or receive onlyvoice or data at one time. However a D-PRS capableradio can transmit or receive message data or GPSposition data at the same time voice is been transmit-ted or received.I-GATEInternet APRSserverPCIt can be checkedat a map site.• The image of D-PRSNOTE:• If “Manual” is selected in the GPS select screen, theprocessed GPS-A code is transmitted according to themanually set position data in “Manual Position.”(p. 10-2)GPS > GPS Set > Manual Position• Please note that if “GPS Auto TX ” is set to anyother setting than “OFF,” the data is transmittedaccording to the setting time.
