GPS + inertial + camera + LiDAR + baro-altimeter = a very precise measurement, right? Not when the respective sensor output timings lack proper synchronization. Only when each piece of data carries an accurate timetag can they together enable optimal performance in multi-sensor fusion systems.

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.
