Core aerospace engineering and protocols for Relative Carrier-Phase RTK.
Standard commercial GPS provides positioning accuracy of 2 to 3 meters—insufficient for automated aerial refueling, formation platooning, or tight multi-aircraft vertipad approaches where wings are separated by only a few feet.
EvtolSync exchanges raw GNSS carrier-phase measurements between aircraft over high-speed sidelink radios. The system computes double-differenced carrier phase solutions (Moving-Base RTK), calculating relative 3D distance between aircraft with +/- 2 cm precision at 100 Hz, enabling rock-solid tight formation flight.
