Providing an accurate timing source for locating the geographical position of a mobile

摘要: The synchronization system uses a TDMA or AMPS air interface to provide timing between previously unsynchronized base stations. of stations is critical when determining the geographical position mobile because determined using time difference arrival method. In order synchronize remote station with serving station, receives signal from and measuring receiving at in relation clock station. determines transmission based on reception distance stations, second synchronizes offset cycles was transmitted.
