Precise time measuring using GPS Satellites 'Simulation in Matlab'

摘要

Recent years Global Positioning System (GPS) has been widely used in industrial and trading activities such as navigation, mapping, power distribution, telecommunication, weather station, digital radio, industrial control systems and research centers,... in these systems information have to transferred between different parts. One of the main exchanged information is time tag, which indicates the precise time of action. Synchronization between these tags is the main portion of these systems. This synchronization produced by one common reference which sends the time synchronizer signal in determined timing intervals to all sections. In this approach GPS satellite, timing signals, Golden Code, methods of coding and decoding of GPS satellite signals, way of correcting time with precise time calculation on GPS receivers and system simulation from GPS satellite transmitter to receiver in Matlab with implementing the receiver hardware will be discussed.
