    Abstract: In one example, a free-flying tethered airship system includes an upper airship adapted to tailor its lift and drag, a lower airship adapted to tailor its lift and drag, and a tether connecting the upper airship to the lower airship such that the upper airship is at least one kilometer above the lower airship. The upper airship is configured to be equiliberally buoyant, while carrying the tether, in a first altitude range. The lower airship is configured to be equiliberally buoyant in a second altitude range, the first altitude range being higher than the second altitude range. A method for stationkeeping of a free-flying tethered airship system is also provided.

    Abstract: Systems and methods for recovering unmanned aircraft and controlling post- recovery motion of the aircraft are disclosed herein. An aircraft recovery system for recovering an unmanned aircraft in flight in accordance with one embodiment of the disclosure, for example, can include an inflatable aircraft recovery system having an inflatable portion with a generally vertical orientation. The inflatable portion can also include a landing pocket extending at least partially therethrough. The landing pocket is sized to receive at least a portion of a fuselage of the aircraft. The aircraft recovery system can also include a guidance system at least proximate to the landing pocket and positioned to guide the aircraft toward the landing pocket.

    Abstract: The present invention is directed to the determination of a relative position between moving platforms, using satellite-based navigation techniques and equipment installed on said platforms. It combines the concepts of observation-space and navigation-space differential systems, and operates a DGNSS base station in a time-varying mode, in order to rely on the built-in differential positioning and navigation capabilities of particular GNSS receivers while minimizing datalink loading and computational load in auxiliary processors. The invention achieves accurate relative positioning and navigation with respect to a moving base station, using DGNSS equipment that assumes it is stationary when operated in a reference station mode.
