Study of the TDM of the GPS Timing in Earthquake Early-Warning Information Transfer

Through the study of earthquake early warning system and found that the transmission of earthquake early warning information is divided into wired and wireless in two ways. Of them single-frequency point of wireless radio transmission improvements, using the time-division multiplexing technology of GPS timing to achieve point-to-point time polling to send earthquake early warning information. Experiments show that the design of earthquake early warning information transmission system runs stability, to achieve reliable transmission of data.
