Advanced IFF Transponder Vehicle Side

This is an improved version of my Identify Friend or Foe (IFF) Transponder System. This is the side of the system that is meant to be installed on a vehicle or aircraft. The system is designed to serve as a transponder and locator system between friendly vehicles and a ground-based radio station. There are 9 operating frequencies or ID numbers that can be assigned to a vehicle by an Air Traffic Controller with the corresponding ATC Side of this system. The system has 3 modes for transmitting data to the controlling radio station: Mode A sends the ID code chosen with a selector switch, Mode B transmits the X and Y grid coordinates of the vehicle, and Mode C transmits the vehicle's altitude.

What you will need:
-3 Instrument Panels
-2 Radio Antennae
-A GPS
-An Altimeter
-A Vehicle to mount it on with electricity

The first instrument panel will control the ID code and transmitting frequency. It will be setup with an up arrow on channel 1, a down arrow on channel 3, a seven-segment display on channel 2, and a switch on channel 4 to turn on the transmitter. I recommend painting this panel green.

The second instrument panel will have a switch on channel 1 for Mode A, a switch on channel 2 for Mode B, and a switch on channel 3 for Mode C.

The third instrument panel will need dials on channels 1 through 4. Channel 1 will show the ground station ID, channel 2 will show the bearing to the station in degrees, channel 3 will show the distance to the station, and channel 4 will show the altitude of the transmitting antenna at the station.
