Navigational beaconing via doppler null scanning (DNS)

A system, comprising:

• a transmitter (Tx) node and a receiver (Rx) node, wherein each node of the Tx node and the Rx node comprises:
• a communications interface including at least one antenna element;
• and
• a controller operatively coupled to the communications interface, the controller including one or more processors, wherein the controller has information of own-node velocity and own-node orientation;
• wherein the Rx node is in motion relative to the Tx node;
• wherein each node of the Tx node and the Rx node are time synchronized to apply one or more Doppler corrections associated with said node's own motions relative to a common reference frame, the common reference frame is known to the Tx node and to the Rx node prior to the Tx node transmitting signals to the Rx node and prior to the Rx node receiving the signals from the Tx node;
• wherein the Tx node is configured for operation in a navigational beacon marking a target location;
• and
• wherein the Rx node is configured to determine a bearing to the Tx node based on the one or more Doppler corrections.
