Direction finding in autonomous vehicle systems

A device, for an unmanned aerial vehicle (UAV) of a first subset of a plurality of UAVs, configured to determine a location, the device comprising:

• one or more receivers or sensors configured to receive first information, each of the one or more receivers or sensors configured to obtain at least a first component of the first information from a source external to the first subset of the plurality of UAVs, wherein one of the one or more receivers or sensors comprises a transceiver configured to communicate with each of the other UAVs in the first subset;
• and
• one or more processors configured to:
• receive a respective first information from each of other UAVs in the first subset;
• determine second information based on a combination of the respective information from each of the other UAVs in the first subset of the plurality of UAVs and the first information;
• and
• communicate the second information to each of the other UAVs in the first subset, wherein the second information is indicative of the location.

A direction finding system configured to direct at least a first subset of a plurality of autonomous vehicles to a location without global navigation satellite system (GNSS) or ultra-wideband (UWB) system guidance, wherein the direction finding system comprises:

• one or more detectors configured to monitor a configuration of the plurality of autonomous vehicles;
• one or more processors configured to receive the configuration from the one or more detectors and determine an instruction to transmit to at least the first subset of the plurality of autonomous vehicles;
• and
• a plurality of indicator lights each configured to transmit at least a subset of the instruction to at least the first subset of the plurality of autonomous vehicles to direct the at least first subset of autonomous vehicles to the location without GNSS guidance or an ultra-wideband (UWB) guidance.
