This tracker not use any gps.
This tracker use a diversity video receiver and one arduino.
Arduino read through the analog inputs the RSSI percentage from receivers.
Sinal its compared and servo tracker follow the stronger RSSI signal.
No pairing, no telemetry, no configuration.
Only you need adjust the value RSSI_MAX and RSSI_MIN in the arduino code about your receiver.
What I used:
FR632 Video Receiver - https://bit.ly/2r9iW38
Arduino Pro Mini - https://bit.ly/2r3WA2X
Note: In the images you can see the arduino pro micro, burned after two tests, its a clone!
In the last image you can see the arduino pro mini that I use.

Two directional antennas
Some wires
Solder Station
1mm solder tip
Solder
Instructions:
With multimeter check the polarity of DC jack pins and solder two wires, positive and negative.
Be careful solder the wires in the correct pin you can burned the step down.
Solder the power supply wires to stepdown, isolate the stepdown with some double side tape.
Rssi pins in the FR632 receivers its the 4 pin from the right to left
Isolate the arduino with some double side tape
Put the arduino like a image.
Solder the wires to
Solder the RSSI pins to A0 and A1 analog pins.
Solder the servo signal wire to pin 5(PWM), ground wire to arduino gnd and positive servo wire to arduino raw pin.
Be careful, you need to adjust the stepdown voltage to 5V or 6V, attention to max servo voltage.
I use a 3S lipo to power FR632.
Turn on the FR632, choose your channel and you are ready to fly.
Good Flights
