Terrestrial position and timing system
A terrestrial positioning and timing system (TPTS) comprising a ground segment and user segment is disclosed that is comprised of a spread-spectrum based range and bearing reference signal, with respect to a reference time, transmitted by an antenna over a broad region of space; and a spread-spectrum based bearing variable signal with bearing specific modulation referenced to a reference time, transmitted using a scanning antenna over a spatial region of space that is more narrow than the spread-spectrum based range and bearing reference signal transmission spatial area. Various embodiments enable the TPTS station and user to support various position, velocity or time services. Most notably, an embodiment with a single TPTS station, active interrogation/transponder reply, and data delivery subsystem can provide a position, velocity, and time solution for the user. Additional embodiments disclosed provide varying levels of user solutions to include bearing, position, velocity, or time.
METHOD AND APPARATUS FOR DETERMINING A POSITION OF USER EQUIPMENT, AND AN ANTENNA SET THEREFOR
There is provided a method for positioning of user equipment. The method for positioning of user equipment, includes: receiving, by the user equipment, a signal from an external antenna, the signal being radiated in a cyclic pattern; measuring, by the user equipment, strength of the received signal, characterizing, by the user equipment, the measured strength to form a signal pattern over a time period; and determining a position of the user equipment based on the signal pattern.

AUTOMATED PACKAGE DELIVERY TO A DELIVERY RECEPTACLE
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.
