A method for navigating an airborne device relative to a target comprises detecting, at an optical detector on the airborne device, an optical signal generated by one or more LEDs on the target; comparing the detected optical signal with a previously-detected optical signal; determining, based on the comparison, a change in location of at least one of the airborne device or the target; adjusting a position of the airborne device based on the determined change in location; predicting a movement of the target based on information indicative of at least one of a position, a rotation, an orientation, an acceleration, a velocity, or an altitude of the target, wherein the position of the airborne device is adjusted based on the predicted movement; detecting an obstacle in a flight path associated with the airborne device and adjusting a position of the airborne device based on detected obstacle information.
