A system for identifying a location of one or more assets in a predefined two-dimensional area comprises at least three tracking stations and one or more tracking tags. Each tracking station selectively emits a vertical laser line upon which is embedded a unique identifier, selectively sweeps its laser line about its central axis such that each tracking station's laser line sweeps across at least a portion of the predefined 2-D area, and selectively transmits a current angle of its laser line as its laser line sweeps about its central axis. Each tracking tag detects a laser line from at least three tracking stations within its line of sight. Each tracking tag decodes the unique tracking station identifier, receives the current angle from the tracking station corresponding to the detected laser line, and stores the decoded unique tracking station identifier and the received current angle.

Disclosed are techniques and apparatuses for transmitting positioning beacon beams including transmitting a plurality of positioning beacon beams from a first node in a first time period using a first order of transmission. Then, the first node transmits the plurality of positioning beacon beams from a second time period using a second order of transmission, where the first order of transmission is different in the second order of transmission.

Improving automated package delivery to mobile delivery receptacles to allow accurate and reliable package deliveries comprises a delivery receptacle for an automated package delivery via an unmanned aerial delivery device. The delivery receptacle is notified of a pending delivery and travels to a receiving location. The delivery receptacle emits infrared (IR) beacons from one or more IR beacon transmitters. An aerial delivery device detects the IR beacon and uses the beacons to navigate to the delivery receptacle. The delivery receptacle receives IR beacon responses from the aerial delivery device and continually or periodically directs the IR beacons in the direction of the aerial delivery device. The aerial delivery device deposits the package in the delivery receptacle. After receiving the package, the delivery receptacle transports the package to a secure location, such as into a garage.
