Is there a solution that sacrifices accuracy to improve urban availability and rate of receipt, because rtk mainly faces the mapping industry, which has higher signal requirements, and has lower availability in the city, so is there a solution that is sub-meter (lower than rtk) but has a high rate of availability.
In the city, due to the complexity of urban road conditions, and there will be more occlusion, in this case, if there is a combination of navigation to maintain and assist, it is also able to achieve very good positioning accuracy, but due to the complex environment, the speed of the car is also slower, which is when real-time construction of the SLAM technology will also be used. The sub-meter positioning scheme is also feasible. But it can only be used in a relatively low-speed scenario. In high-speed scenarios, it is necessary to use high-precision to assist, because the required positioning accuracy will be higher. Comparatively speaking, low-speed will be assisted by other devices, which can solve the more complex environment in the city.
