Abstract:
1. A method of providing a relative navigation solution between a first vehicle and a second vehicle, the method comprising the steps of: receiving a first signal, as transmitted by a second vehicle transceiver, at the first vehicle utilizing a first vehicle antenna array including at least three spatially separated antenna elements operably connected to a first vehicle transceiver; calculating a relative position of the second vehicle based upon time, altitude, and phase differences included in the first signal received by the first vehicle transceiver; determining a relative navigation solution for the second vehicle based on the relative position of the second vehicle; transmitting a second signal from the first vehicle transceiver, the signal including the relative navigation solution for the second vehicle; wherein the first vehicle transceiver is configured to transmit and receive via synchronized frequency hopping communication, the first vehicle transceiver frequency being time synchronized with the second vehicle transceiver frequency.
