基于GPS的船舶数据模拟系统的研究

he main research of this text is the data simulator of GPS, the function of this simulator is to simulate data of the GPS, show dynamic position, speed and course of the vessel, and send these datas to the equipment through the serial port of RS232 in real time. The data simulator of GPS system are divided into the module of showing in real time and the module of data transmission. The emphasis of this text is the module of data transmission, which purpose is to output data through several serial ports of RS232. The connections of two pieces of module of this system have realized the function of the data simulator of GPS.
