An approach is provided that generates a current coverage area by receiving beacon position data of current beacon locations, with at least some of the beacons being moveable beacons. Object position data is retrieved for current locations and trajectories of moveable objects in a geographic area that are currently being tracked by the beacons. An anticipated coverage area is computed based on comparing the object position data with the current coverage area. Instructions are then wirelessly transmitted to some of the moveable beacons in order to move the beacons to a different set of locations based on the anticipated coverage area.

A method for tracking an object includes associating a beacon with a responder; transmitting a polling signal from the beacon to the responder; receiving a response from the responder; entering a low power state on the beacon for a predetermined duration; and transmitting an alert from the beacon responsive to a subsequent signal from the beacon failing to result in receiving a subsequent response from the responder. Embodiments also include a system in which the beacon and responder are configured to perform the described functions. In various embodiments, the duration during which the beacon remains in the low power state is predetermined based either on a default factory setting or a user adjustable setting.

An RSSI positioning method based on frequency-hopping spread spectrum technology, comprising: calibration stage: measuring the RSSI values of a plurality of channels at fixed points, and recording and calculating the ranging parameters in an RSSI ranging model; system preparation: deploying a positioning anchor node, and realizing synchronization between a target node and the anchor node; conducting communication on the target node by respectively utilizing a plurality of channels to obtain the RSSI values; signal processing stage: processing the RSSI into signal strength amplitude and performing optimization; and positioning stage: calculating a distance and the target node position on a positioning server according to each of the signal strength. The present invention solves the problem that low RSSI positioning precision cannot satisfy the actual requirements because a traditional RSSI positioning method is limited to factors such as multipath signal transmission, co-channel interference, obstacle interference and low coordinate calculation precision of a trilateration method.

Systems and methods for determining an indication of locationing accuracy are disclosed herein. In some embodiments, an antenna deployment including multiple antennas and corresponding locations for the antennas is obtained. Then, one or more radio characteristics are determined for ubiety locations based on the antenna deployment and an indication of locationing accuracy for the ubiety locations is determined based on the one or more radio characteristics. In this way, an antenna deployment can be evaluated for locationing accuracy. This may be used by a network engineer or an automated system to determine and/or refine an antenna deployment.

The messages include information that identifies the aircraft passenger service unit and the near field communication interface sending the respective message.

Drone resilience against electronic warfare (EW) is enhanced by repurposing downed drones as navigational beacons or communication nodes within a mesh network. The techniques leverage remaining capabilities of the downed drones to support the operational continuity of active drones, creating a self-sustaining and robust aerial network. The downed drones are repurposed into passive navigational beacons or communication nodes to assist active dronesthose still flying on a same or overlapping missionin overcoming EW threats. The navigational beacons may include radio frequency (RF) signals or visual signals (e.g., infra-red (IR) or light emitting diode (LED) lights) encoded with location or position data of the downed drone. Active drones may use this position data to estimate their own positions and navigate accordingly to continue their missions.

A reach and placement tool includes an eyepiece, an orientation sensor, a distance sensor, and a controller. The controller is configured to obtain a distance value and an orientation from the distance sensor and the orientation sensor when the reach and placement tool is directed towards a point of interest at a particular location. The controller is also configured to determine a coordinate of the point of interest using the distance value and the orientation, and compare the coordinate of the point of interest to a reach envelope to determine if the point of interest is within range of a particular reach apparatus.
