摘要
利用先进的组合导航技术组成GNSS系统,充分发挥GPS和GLONASS各自优势,并采用航迹推算(DR)技术、精确地图匹配(DMAP)技术组成GNSS/INU/DMAP组合导航系统,提高了系统精度和可靠性,并利用GSM网进行定位数据的无线传输。该系统将卫星导航技术、惯性导航技术、计算机技术、无线通讯技术融合在一起,实际跑车试验验证了系统具有全方位、全天候、无遮挡、高精度的特点。
The GPS and GLONASS are combined into GNSS system by means of advanced integrated navigation technologies. The superiority of GPS and GLONASS could be put into effect and relatively complemented. GNSS/INU/DMAP system is composed using GNSS, DRS and map matching. The reliability and precision of the system would be enhanced. The data of positioning are communicated through GSM. This system combines satellite navigation, inertial navigation, and wireless communication technologies. The advantages such as all-direction, 24 hours standby, non-shadowed characteristics, and high precision are demonstrated by trial run experiment.
