1. A system comprising:
a transmitter node and a receiver node, wherein each node of the transmitter node and the receiver node comprises:
a communications interface comprising 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 each node of the transmitter node and the receiver node are in motion relative to each other,
wherein each node of the transmitter node and the receiver node are time synchronized to apply Doppler corrections associated with said node's own motions relative to a common reference frame, wherein the transmitter node is configured to apply the Doppler corrections to signals using Doppler null steering along a plurality of Null directions based on the transmitter node's own motions and based on a protocol,
wherein the common reference frame is known to the transmitter node and the receiver node prior to the transmitter node transmitting the signals to the receiver node and prior to the receiver node receiving the signals from the transmitter node,
wherein the receiver node is configured to determine a relative position of the transmitter node based on the signals based on the Doppler null steering based on the protocol,
wherein the protocol comprises a protocol modulation, and wherein the receiver node is configured to receive the signals transmitted based on the protocol modulation.
