LOCATING METHOD AND DEVICE, AND COMPUTER STORAGE MEDIUM
A locating method and device, and a computer storage medium are provided for realizing that an anchor node apparatus locates a beacon apparatus in a range of 360 degrees. The method is applied to an anchor node apparatus. The anchor node apparatus comprises at least three first antennas, wherein a set location of at least one first antenna is not collinear with set locations of the remaining first antennas. The method comprises: receiving a signal sent by a second antenna of a beacon apparatus by means of each of the first antennas; according to a phase of each of the first antennas for receiving the signal, obtaining a phase difference between every two first antennas for receiving the signal; extracting at least three phase differences closest to a pointed orientation; and based on the at least three phase differences, determining the orientation of the beacon apparatus.

Frequency hop based positioning measurement
Positioning reference signals are transmitted in a downlink direction from base stations (200) of a wireless communication network to a wireless communication device (100) or in an uplink direction from the wireless communication device (100) to base stations (200) of the wireless communication network. According to a frequency hop pattern, a radio interface of the wireless communication device is switched between multiple different frequency ranges. In this way, the wireless communication device (100) can receive the downlink positioning reference signals on multiple different frequencies defined by the frequency hop pattern or send the uplink positioning reference signals on multiple different frequencies defined by the frequency hop pattern.

Drone encroachment avoidance monitor
Disclosed are examples of systems, apparatus, methods and computer program products for locating unmanned aerial vehicles (UAVs). A region of airspace may be scanned with two scanning apparatuses. Each scanning apparatus may include one or more directional Radio Frequency (RF) antennae. The two scanning apparatuses may have different locations. Radio frequency signals emitted by a UAV can be received at each of the two scanning apparatuses. The received radio frequency signals can be processed to determine a first location of the UAV.
