The second interrogator includes a second receive antenna, and circuitry configured to generate, using the RF signal synthesis information, a third RF signal; and generate, using the third RF signal and a fourth RF signal received from the target device by the second receive antenna, a second mixed RF signal indicative of a distance between the second interrogator and the target device.

Abstract: A system for tracking position of objects in an industrial environment includes an interrogator, a transponder, and a processor. The interrogator transmits a signal and provides a first reference signal corresponding to the transmitted signal. The transponder provides a response signal. The interrogator receives the response signal and provides a second reference signal corresponding to the response signal. The processor determines a location of either the interrogator or the transponder, relative to the other, based on the two reference signals.

Abstract: An autonomous aerial vehicle includes a flight controller and a mission manager in communication with the flight controller. The flight controller is configured to navigate the autonomous aerial vehicle. The mission manager is configured to receive mission data. The mission data identifies both a landing zone and a designated touchdown zone located within the landing zone. The mission manager is further configured to provide flight control data to the flight controller. The flight control data causes the flight controller to navigate the autonomous aerial vehicle to a predetermined distance from the landing zone. The mission manager is further configured to determine, subsequent to the autonomous aerial vehicle reaching the predetermined distance, whether landing at the designated touchdown zone is feasible.

Abstract: An aircrew automation system that provides a pilot with high-fidelity knowledge of the aircraft's physical state, and notifies that pilot of any deviations in expected state based on predictive models. The aircrew automation may be provided as a non-invasive ride-along aircrew automation system that perceives the state of the aircraft through visual techniques, derives the aircraft state vector and other aircraft information, and communicates any deviations from expected aircraft state to the pilot.
