1. A flight control system for a rotorcraft comprising:

  • a processor and a non-transitory computer readable storage medium with an executable program stored thereon, the executable program including instructions for;

    asynchronously receiving position coordinates of a rotorcraft from a position sensor, each received position coordinate comprising a coarse resolution position coordinate and a fine resolution position coordinate; and

    determining whether the coarse resolution position coordinates and the fine resolution position coordinate of the received position coordinates correspond with each other, determining comprising calculating a difference between a presently received position coordinate and a previously received position coordinate, and comparing the calculated difference to a threshold, wherein the threshold is based on a velocity of the rotorcraft.
