Abstract: A method of providing a relative navigation system by projecting into space from a first object a grid that is repeatedly detected from a second object having a second relative reference frame associated with a second origin point on the second object and using range and attitude between the objects to adjust the attitude or range of at least one of the first and second objects.

Abstract: A refueling drogue adapted to connect to a refueling hose extending from a refueling aircraft. The drogue may include an active stabilization system adapted to effectively stabilize the refueling drogue via control surfaces on the refueling drogue when the refueling drogue is placed in an airstream.

Abstract: An airborne tracking system including a radiation emitter, a radiation receiver and a signal processor. The radiation emitter is adapted to direct radiation to a positioning area a defined distance from the radiation emitter, the radiation carrying a modulated location signal containing information corresponding to positions within the positioning area. The radiation receiver is adapted to receive at least a portion of the emitted radiation carrying the modulated signal and output a signal to the signal processor indicative of the modulation of the location signal of the received radiation. Signal processor is adapted to process the outputted signal and identify a position within the positioning area indicative of the location in the positioning area of the received radiation.
