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.

Abstract: A system may include a transmitter node and a receiver node. Each node may include 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 of the receiver node has information of own node velocity and own node orientation. The receiver node may be in motion and the transmitter node may be stationary. Each node may be time synchronized to apply Doppler corrections associated with said node's own motions relative to a common reference frame. The common reference frame may be known to the transmitter node and the receiver 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.

Abstract: A system is disclosed. The system may include a receiver or transmitter node. The receiver or transmitter node may include a communications interface with an antenna element. A controller may include one or more processors and have information of own node velocity and own node orientation relative to a common reference frame. The receiver or transmitter node may be time synchronized to apply Doppler corrections to signals, the Doppler corrections associated with the receiver or transmitter node's own motions relative to the common reference frame, the Doppler corrections applied using Doppler null steering along Null directions. The system may be configured to, via the Doppler null steering, at least one of: track an expendable asset of the system relative to a target; discover a rendezvous node; or identify at least one of a network relay node or a relay location for a network relay node.

Abstract: A system includes at least a receiving (Rx) and transmitting (Tx) node in relative motion, the Rx node aboard an aircraft or other vehicle. The Rx and Tx nodes include a communications interface with antenna elements and a controller including one or more processors, each node knowing own-node velocity and orientation relative to a common reference frame known to both nodes. The Rx or Tx node may be time synchronized to apply Doppler corrections associated with each node's own motions relative to the common reference frame. The system may replace, enhance, or operate as a ground-based navigational station (e.g., wherein the Tx node operates as a VOR or NDB beacon) or a vehicle-based approach or landing system (e.g., wherein the Tx node is also vehicle-based), e.g., the Rx node determining a relative bearing to the Tx node based on Doppler corrections with respect to Tx-node transmissions.

Abstract: An electronically steerable antenna includes an embedded antenna processor and orientation sensor, separate from any orientation sensor within a corresponding GPS receiver. The orientation sensor tracks orientation changes in the mobile platform including the electronically steerable antenna, and an antenna processor updates beams and nulls produced by the antenna to track a real-world location based on the orientation changes. The embedded antenna processor periodically compares the orientation data from the embedded orientation sensor with orientation data from systems aboard the mobile platform to calibrate.

Abstract: Embodiments of the inventive concepts disclosed herein are directed to systems and methods for managing global navigation satellite system (GNSS) receivers. A master GNSS receiver can receive, via an antenna system, a GNSS signal. The master GNSS receiver can determining, using the received GNSS signal, information including positioning, navigation and timing (PNT) or positioning, velocity and time (PVT) information. The master GNSS receiver can generate a master GNSS signal using a signal generator and the determined information, and a message indicating that the master GNSS signal is a trusted GNSS based signal. The master GNSS receiver can communicate, via a distribution hub, the generated master GNSS signal and the message to a plurality of GNSS receivers co-located with the master GNSS receiver, for recovering the PNT or PVT information from the master GNSS signal.
