Abstract
On the basis of the semi⁃physical simulation platform,the hardware and software of GPS information processor were designed. The signal received by coaxial high frequency feeder is sent to the GPS modular to receive the information source with NMEA0183 protocol format and pulse per second signal used for accurate time synchronization. The signal processing cir⁃cuit based on AT89C52 is used to extract the navigation information,and then send the GPS information source and relevant in⁃formation to the system master through serial communication port for using. The status bit in information frame is queried with the single chip microcomputer,and then the bilateral switch chip is used to select the light emitting diode to indicate the working con⁃dition. The analysis,extraction and forwarding for a variety of navigation information can ensure the real⁃time and reliably receiving and processing of the effective information,avoid occupying the main server′s processing time,and improve the real⁃time perfor⁃mance and effectiveness of information utilization.关键词
