The simplest human generated position report for APRS is to include a gridsqare at the start of a packet, such as: >GG##gg/- coments.... This format supports the more than one hundred different APRS Icons. A subset of those ICONS thought to be usefull for this ISS experiment are listed below. To appear as something other than a HOUSE, simply replace the "/-" shown in the example grid square example with one of the following pairs: /- House with VHF vertical* /' Small AIRCRAFT /* SnowMobile /+ Red Cross \+ Church /, Boy Scouts \, Girl Scouts \- House with HF dipole* /; Campground* \; Park/Picnic area* /< Motorcycle* /= RAILROAD ENGINE /> CAR* /C Canoe \C Coast Guard /E EYEBALL /H HOTEL /K School \L Lighthouse /N NTS Station \N Floating Buoy /O BALLOON /R REC. VEHICLE* \R Restaurant /S SHUTTLE \S Satellite/Pacsat /T SSTV* /U BUS* /V Amateur TV* /X HELO /Y Sailboat* /[ Jogger, walker or runner* /^ LARGE AIRCRAFT* /` Dish Antenna /a AMBULANCE* \a ARRL ARES etc /b BIKE* /d Fire dept /e HORSE /f FIRE TRUCK* /g Glider /h HOSPITAL \h HAM store /i IOTA (islands on the air) /j JEEP* /k TRUCK* /o EOC /p ROVER (puppy) /r ANTENNA /s SHIP (power boat)* /u TRUCK (18 wheeler)* /v VAN* (*) NOTE. Those ICONS marked with a (*) will actually show on the Kenwood D7 and D700 front panel displays.
