RC-Link and Telemetry

2 nodes who have compatible parameters and are within range should sync automatically, a solid green LED indicates success. This should be good enough for testing for now.

In python, simply open a serial communication on the appropriate COM port.

Tracking Antenna
...
A directional antenna would be combined with 2 servos, controlling its pan(yaw) and tilt(pitch). (just yaw)
The antenna would have a GPS chip on board in a fixed location relative to the antenna. The distance and offset would be measured and inputted on the ground station, and sent to the Nucleo.
During operation, the ground station would stream the GPS position of the drone to the tracking antenna system. From there, simple trigonometry can be applied to find the correct pan and tilt.
Questions to be answered/Discussion needed
The tracking system is currently open-loop, which is probably fine since we have a 30~60-degree effective angle.
A camera might be added for debugging/verifying the tracking accuracy, but NOT for tracking (as it will probably be very bulky)
How effective is tracking antenna signal wise when there is no light of sight?
