AI Technical Summary
In complex urban environments, the accuracy of RTK positioning technology cannot be maintained. Existing methods increase product costs and technical complexity, while the ambiguity fixation rate decreases, affecting positioning accuracy.
By traversing the raw observation information of satellite channels, the current working environment is identified, and different positioning calculation processes are selected according to the environment type, including pseudorange single-point positioning, extended Kalman filtering, interepoch difference calculation and LOG verification of observations, satellites affected by obstruction are eliminated, and high-precision positioning is achieved.
It improves positioning accuracy and accuracy retention in complex urban environments, reduces reliance on inertial navigation and other sensors, lowers computational burden, and maintains high-precision RTK positioning.
