摘要： Three fixed reference stations (SO, S1, S2) having known positions comprise Omega receivers (10. 16, 18). Phase measurements made at all three stations are assembled at a master station (SO), utilising landlines (24) or radio links and, using the known positions of the stations, a central processing unit (12) calculates not merely the offset of the master station as measured from the true position but also the errors in the azimuths of the propagation directions of the received signals. The position measurement of a vehicle (V) with an Omega receiver (26) is corrected on the basis of the offset and also the errors in the said azimuths. Sufficient accuracy is achieved for finding the position of land based vehicles (V) whose position may be calculated subject to the corrections in the master station (SO) on the basis of raw data transmitted to the master station over a link (30). Alternatively the azimuth corrections may be transmitted to the vehicle over the link (30). Two fixed stations suffice if they can measure absolute phase.

摘要： A wireless terminal receives signaling information, pertaining to a reference signal transmission in at least one specifically designated sub frame, the signaling information including a list, the list including base station identities. The terminal determines, from at least one of the base station identities in the list, the time-frequency resources associated with a reference signal transmission intended for observed time difference of arrival (OTDOA) measurements from a transmitting base station associated with said one base station identity. The time of arrival of a transmission from the transmitting base station, relative to reference timing, is measured. The wireless terminal can receive a command from a serving cell to start performing inter-frequency OTDOA measurement on a frequency layer containing reference signals, the frequency layer distinct from the serving frequency layer, the serving frequency layer not containing positioning reference signals. The wireless terminal can perform OTDOA measurements subsequent to the reception of the command on a carrier frequency different from the serving cell carrier frequency. A base station transmitter can jointly schedule a reference signal transmission from a plurality of base station transmitters for the purpose of OTD estimation enhancement, and transmit identical reference signals from the plurality of base station transmitters, the reference signals being identical both in the signal sequence and time-frequency resources used for transmission.

摘要： A method and system for navigation comprising a plurality of transmitters (11, 13, 100, 102), pairs of which are excited from a common frequency source, and a receiver (18) responsive to and deployed within the wave fields (126, 108, 110, 128, 116, 132) created by the transmitters. The receiver (18) is provided with its initial coordinate position (R) and determines movement therefrom by detecting beat frequency cycles resulting from the relative movement between the receiver and the transmitters of a transmitter pair. The receiver (18) position change (S) is computed according to the beat frequency cycles detected. In a preferred embodiment, transmitter pairs are arranged generally perpendicularly to establish a coordinate system and transmitters of a transmitter pair radiate different frequencies that are precisely related to a common excitation frequency source. The receiver (18) detects the transmitted signals, compensates for the precise frequency relationship employed at each transmitter pair, and compares the signals from each transmitter pair to detect beat frequency cycles which are used to compute receiver position change.
