In-flight refueling requires sustained minimal separation between paired aircraft with little room for error. In or near combat zones, wide-area GPS-denial or spoofing means that an GPS-independent system must be available. Regardless of the selected sensor package, a common set of properties must be satisfied to facilitate mid-air docking: a high degree of accuracy, precision, and integrity.
The U.S. Air Force Research Laboratory’s AFWERX program awarded a Phase II SBIR contract to Masten Space Systems to develop and demonstrate a lunar positioning and navigation network prototype. With functionality similar to GPS, the network will enhance cislunar security and awareness by enabling navigation and location tracking
