We are inseparable from navigation in our daily life, but many of our friends will encounter navigation, but there are deviations or lags in some places, and they go the wrong way. At the 13th General Assembly of the International Committee for Global Navigation Satellite Systems, the Beidou system also demonstrated the high-precision lane-level navigation system. How is it effective?
On the demonstration screen of the bus, the Beidou centimeter-level positioning data and the positioning data based on the mobile terminal are simultaneously connected, and the vehicle trajectory is compared. We can clearly see that the lane-level positioning trajectory is exactly the same as the actual driving position of the vehicle. It accurately describes the driving information such as lane change, stop, U-turn, and turn of the vehicle. However, the mobile phone positioning trajectory will drift to the reverse lane and the non-motor vehicle lane, and there will be obvious deviations in the position during the turning and turning.
US Representative Rick Hamilton: I am impressed by the stability of our journey. This is the future of the transportation industry, which can effectively avoid accidents and reduce the risk of transportation.
The position information accepted by the lane-level navigation and positioning is based on the high-precision signal acquired by the Beidou satellite through the ground-based augmentation system, and then merged with the high-precision map data to be perfectly displayed in the user terminal. It is understood that at present, the Beidou ground-based augmentation system has the basic service capability of providing high-precision positioning in the meter, decimeter, centimeter and post-processing millimeters in real time.
