Abstract
A system may include a receiver node. The receiver node may include a communications interface and a controller. The receiver node is time synchronized with a transmitter node to apply Doppler corrections to the receiver node's own motions relative to a common reference frame. The receiver node may be configured to: The receiver node may be configured to: based at least on the receiver node being time synchronized with the transmitter node to apply Doppler corrections and the common reference frame, use Doppler null scanning (DNS) to determine DNS derived information, the DNS derived information including a bearing and the receiver node's relative position relative to the transmitter node; and output a position, navigation, and timing (PNT) solution based at least on the DNS derived information.
