摘要

城市地区为全球定位系统(GPS)车辆定位系统提供了独特的问题。只有gps的传播只能在很短的间隔内使用。为了解决这些问题，GPS传感器增加了航位推算能力。该系统使用低成本的振动陀螺仪。车辆的里程表输出与GPS相结合，为城市环境提供准确，强大的定位系统。该系统在恶劣的城市环境中表现良好。

GPS/dead reckoning for vehicle tracking in the "urban canyon" environment

Urban areas provide unique problems for Global Positioning System (GPS)-only vehicle location systems. GPS-only propagation can only be used over short intervals. To combat these problems, a dead reckoning capability is added to a GPS sensor. The system uses a low-cost vibrational gyro. The vehicle's odometer output combines with GPS to provide an accurate, robust positioning system for urban environments. The system performs well in harsh urban environments.
