Abstract: An enhanced positioning and navigational system for use within a building or otherwise separated by a line-of-sight barrier from an orbiting global navigation satellite system such as Navstar GPS. An antenna placed at a known location within line of sight of orbiting global navigation satellites receives global position and navigation signals and relays the signals through the line-of-light barrier to an identifier which identifies the signals and couples the signals for individual broadcast from each of an array of broadcast antennae located at known fixed locations within the building (behind the line-of-sight barrier). A receiver located within the building receives the signals broadcast from the antenna array and through use of a processor interprets the signals to provide position and navigation information to the user of the receiver. In an alternate embodiment, a signal generator generates navigation and positions information signals of a multiplicity of broadcast beacons.
