Systems, methods, apparatuses, and computer program products for using angle error groups (AEGs) to improve angle of arrival (AoA) positioning may be provided. For example, for a specific received signal, one or more receiving antenna elements that can be considered to have almost the same incident angle within a certain margin may be defined as a group. The group of receive (Rx) antenna elements (or a group of Rx antennas) may be defined as an AEG. The configuration of an AEG for each TRP and the AEG may be used for AoA measurement and reporting. The gNB or transmit receive point (TRP) may perform AoA measurements and may determine an AoA for the AEGs.

An autonomous search light system for being mounted to an aircraft includes a search light for emitting an adjustable light output; an RF receiver with at least two RF antennas for receiving RF signals emitted by an RF transmitter; and a controller for determining a position of the RF transmitter in relation to the search light from the received RF signals and for controlling the search light based on the determined position of the RF transmitter.

A location system for determining a position of a device is described here. The location system comprises a memory and a processor, the processor executes the computer-executable instruction to perform operations. The operations include sending a first instruction to a locator beacon to determine a first location of the device based on angle of arrival calculation of a first set of one or more packets received from the device. The operations further include sending a second instruction to the device to determine a second location of the device based on angle of departure calculation of a second set of one or more packets received from the locator beacon. Furthermore, the operation includes receiving the first location from the locator beacon and receiving the second location from the device. The operations further include determining the position of the device based on a function of the first location and the second location.

Systems and methods for mapping location and characteristics about wireless emitters are described. The systems and methods advantageously use correlative receivers for observing the emissions from the wireless emitters without decrypting or decoding information included in the emissions from the wireless emitters to allow for tracking location and emitter class and type in real-time. The real-time geolocation and emitter class information for many receivers in a geographic area can be determined and overlaid on a map, for example.

A method of communicating with a tire pressure monitoring system (TPMS) sensor module includes transmitting, by the TPMS sensor module, a TPMS signal that includes a sensor identifier of the TPMS sensor module; performing, by an interface device, an angle of arrival measurement on the TPMS signal to whether an angular direction thereof with respect to an antenna array of the interface device is within a predetermined angular window; and determining, by the interface device, whether or not to communicate with the TPMS sensor module including establishing communication with the TPMS sensor module on a condition that the angular direction is within the predetermined angular window and not establishing communication with the TPMS sensor module on a condition that the determined angular direction is not within the predetermined angular window.

The present disclosure describes systems and methods for escorting small unmanned aircraft (herein drones). An escorting drone approaches the escorted drone and transmits to it an escort signal. In an embodiment, the escort signal is a GNSS signal fashioned to be the same as the GNSS signal that would be received by the escorted drone, other than being slightly stronger in signal strength and having slightly altered component delays. In another embodiment, the escort signal is a radio frequency control channel signal. Escorting may be utilized to guide a drone from a preprogrammed point to a docking zone in a droneport; to guide a drone though an urban canyon or inside a building where GNSS signals are not reliably received; to retrieve a drone with which communications has been lost; or to escort a drone to safety out of a no-flight zone such as around an airport.
