Abstract: A cellular telephone communication system has at least one base station and a plurality of remote mobile stations in which both base and mobile stations have RF transceivers which communicate with each other using periodically repeated pulse sequence epochs whose time patterns are known at both transmitting and receiving station. Each mobile station transceiver, during normal operation, establishes and maintains synchronization between the start of a received pulse epoch at the mobile station and a subsequent beginning of a responsive transmitted pulse epoch. An agile antenna system is located at the base station and includes at least one scanning antenna spaced a selected distance from a central reference point. The scanning antenna is effectively rotated relative to the central reference point and adapted to receive RF transmissions from a selected mobile station, and a direction or bearing detection processor is connected to antenna systems for detecting from received RF transmissions from the selected mobile station the bearing to the selected mobile station from the base station. The bearing sensing processor is one selected from amplitude sensing, phase sensing or frequency sensing or a combination of these sensing principles. A range measuring processor circuit also at the base station measures the time interval from the start of the base station's transmitted pulse epoch to the start of a pulse epoch subsequently received from the selected mobile station and derives range to the selected mobile station therefrom.

Abstract: A method of avoiding near-far interference problems in a cellular ray of navigation signal beacons having selected CDMA or GPS-like navigation signals. The navigation signals from adjacent navigation signal beacons are pulsed so that adjacent navigation signal beacons do not broadcast navigation signals simultaneously and the multiple frequencies are coordinated in a time divisional multiplex manner. In another aspect, the near-far interference problem is avoided by using multiple frequencies in time division multiplexing and coordinating the use of the multiple frequencies and the time division multiplexing to assure avoidance of the near-far interference problem.

Abstract: The present invention relates to a no outage GPS/AM position finding system wherein a GPS system having a plurality of satellites transmits time and location data over radio frequency signals to enable a mobile GPS receiver station on the ground to determine its position, and a cellular telephone is carried with the mobile GPS receiver, traveling in range of a plurality of conventional ground based amplitude modulated (AM) transmitters for transmitting AM signals. Each mobile GPS receiver station includes phase detection means for simultaneously receiving a predetermined number of the AM signals, and measuring the changes in phase of each of the AM signals as the mobile GPS receiver travels, and deriving therefrom an AM position signal. A reference station for receiving the GPS and AM signals provides correction signals via a cellular telephone network which receives and transmits the correction signals to the mobile GPS receiver station. The last accurate GPS position signal is used for resolving any ambiguities in the AM radio position signal and to accommodate the lack of synchronization in the AM transmitters. The reference station measures the frequency and wavelength variations in the AM signals and conveys same to the mobile GPS receiver station by the cellular telephone. The AM position signal is activated upon detecting outages or blockages in the GPS signals.

Abstract: Base station and system modifications to a digital cellular telephone system that measures location of a mobile station from its normal transmissions, and can forward the measured position to that station or some other authorized caller or service on the communication network. Range measurement is enabled without modification of mobile station equipment because of the synchronization between received pulse epochs and transmitted ones that are required for normal operation in digital telephony. Range measurement is made at a base station currently in contact with the mobile station by measuring the time interval from the start of its own transmitted pulse epoch to the start of a pulse epoch subsequently received from the mobile station, then dividing that time interval by twice the velocity of radio waves. Direction from the base station is determined, in a preferred embodiment, by use of a planar phase steered antenna array synchronized to pulse sequences from the mobile station.
