Configurable rotary encoder including two point inflight auto calibration and error adjustment

A landing gear system comprises:

• a landing gear collar;
• a strut assembly supported by the landing gear collar, the strut assembly including a piston that is adjustable between a fully extended position and a fully compress position;
• a rotary encoder rotatably coupled to the strut assembly, the rotary encoder configured to rotate in response to adjusting the piston and to output a data value indicative of a voltage level in response to rotating the rotary encoder;
• and
• a controller in signal communication with the rotary encoder and configured to determine a stroke of the piston based on the data value output from the rotary encoder,
• wherein the controller stores a plurality of pre-determined voltages that are cross-referenced to a respective stroke position of the piston, and determines the stroke based on a comparison between the voltage level and the plurality of pre-determined voltages.
