1. A system, comprising:
a receiver node, comprising:
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 receiver node is time synchronized with a transmitter node to apply Doppler corrections to the receiver node's own motions relative to a stationary common inertial reference frame, wherein the stationary common inertial reference frame is known to the receiver node and the transmitter node prior to the transmitter node transmitting signals to the receiver node and prior to the receiver node receiving the signals from the transmitter node.
