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.
UrsaNav and ADVA have conducted an enhanced long-range navigation (eLoran) field trial using UrsaNav’s eLoran receiver and ADVA’s Oscilloquartz grandmaster clock technology. The successful demo showed that eLoran offers a robust and reliable backup for GPS and other GNSS and could be used to provide an assured position, navigation, and timing (PNT) service.

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

Situational awareness and risk assessment are key to UAV mission planning in both dense urban areas and, surprisingly, in open-sky areas such as over ocean coastlines. Successful results depend closely upon scheduling for the most advantageous hours, or even minutes, to overfly particular areas.

The addition of alternative sensors such as cameras, magnetometers, and small ranging radios increases the likelihood of a mismodeled and/or faulty sensor, affecting the accuracy and performance of the overall navigation solution. Unlike two-sensor systems such as GPS-inertial integration, systems of three or more sensors present the problem of ambiguity as to which sensor is adversely affecting the solution. This presents the need for a robust framework that can maintain navigation integrity despite the additional sensor modalities.
