Abstract: PROBLEM TO BE SOLVED: To provide a method for obtaining an accurate global positioning satellite(GPS) by calibrating a frame boundary, while GPS timing is set as a reference. SOLUTION: Calibration of time is possible, by determining a time difference Δt between the GPS reference time (or a pulse) and an n-th frame boundary. The time difference Δt and a frame boundary identifier are supplied to all devices or a part of devices which are equipped with GPS receivers. As a result, the device equipped with the GPS itself be made to be synchronized with the GPS timing. When the device is synchronized with the GPS timing, it can retrieve a GPS signal, by using information which a geographical position server, such as a WAG server, supplies.

Abstract: PROBLEM TO BE SOLVED: To provide a method for obtaining an accurate satellite navigation system (GPS) by particularly calibrating a frame boundary to the GPS timing in the geographical location in a radiocommunication system. SOLUTION: This method is typically composed of a stage for deciding calibration time by using a pseudo-range and a local time reference related to at least four detected artificial satellite signals and a stage for transmitting the calibration time, and this local time reference has the already known relationship with artificial satellite time. Time calibration is attained by deciding a time difference Δt between reference GPS time (or a pulse) and an (n)-th frame boundary.

Abstract: Disclosed is a method for deriving accurate global positioning satellite (GPS) timing by calibrating frame boundaries to GPS timing. Time calibration is achieved by determining a time, difference DELTA t between a reference GPS time (or pulse) and an nth frame boundary. The time difference DELTA t and a frame boundary identifier specifying the nth frame boundary are provided to a device equipped with a full or partial GPS receiver so that the GPS equipped device may synchronize itself to GPS timing. Upon synchronizing itself to GPS timing, the GPS equipped device may search for GPS signals using information provided by a geographical location server, e.g., WAG server.

Abstract: Disclosed is a method for deriving accurate global positioning satellite (GPS) timing by calibrating frame boundaries to GPS timing. Time calibration is achieved by determining a time difference At between a reference GPS time (or pulse) and an nth frame boundary. The time difference At and a frame boundary identifier specifying the nth frame boundary are provided to a device equipped with a full or partial GPS receiver so that the GPS equipped device may synchronize itself to GPS timing. Upon synchronizing itself to GPS timing, the GPS equipped device may search for GPS signals using information provided by a geographical location server, e.g., WAG server.
