Research on GNSS Differential Positioning Methods Based on Smartphones
This article explores the method and feasibility of using smartphones to achieve differential positioning of global navigation satellite systems (GNSS). By combining the built-in GNSS receiver and related sensors of smartphones with differential positioning technology,we test the positioning accuracy of smartphones. Experimental results show that the positioning accuracy of smartphone dif-ferential positioning can reach the sub-meter level,and it exhibits good accuracy in positioning. Therefore,using smartphones to a-chieve GNSS differential positioning provides users with a convenient and efficient positioning solution,which helps to promote the de-velopment of mobile positioning technology.
