摘要
全球卫星定位系统(GPS)可以对海陆空进行全方位的实时定位与导航,其应用日益广泛,通过GPS定位系统及其信息接收装置可以实现对当前所在位置的确定。系统使用天线接收GPS卫星信号,并在μC/OS操作系统下用NIOS处理器进行分析处理,以保证其实时性,最终输出位置、速度等信息进行定位。本系统通过实验测试验证,定位具有较高的准确性和实时性。
Global positioning system (GPS) is a real-time satellite navigating and positioning system which can be used in sea, land and airspace. It is more and more widely used. It can determine the current location through GPS and its information receiving device. The satellite signal from GPS is received by this system through antenna and processed by NIOS processor un- der the μC/OS operating system to ensure the real-time performance. Final the positioning purpose is realized by information out- put of location and velocity. The experiment verification indicates that the system has high accuracy positioning and real-time per- formance.
