Abstract

The invention discloses a dual-channel satellite navigation differential data receiving method, a receiver and a storage medium. The receiver of the invention searches for a first target broadcast signal having differential data through a primary channel, processes the first target broadcast signal, acquires first coordinates, first differential data and a frequency point of a first base station in the first target broadcast signal, and sends the first differential data to a navigation system; and searches for a second broadcast signal with differential data through a secondary channel according to the frequency point, processes the second target broadcast signal, acquires second coordinates and second differential data of a second base station in the second target broadcast signal, compares the first coordinates with the second coordinates, switches the secondary channel into the primary channel when determining the second base station as a target base station, and sends the second differential data to the navigation system to ensure that the differential data will not be cut off and seamless switching is realized.

Description

technical field [0001] The invention relates to the technical field of broadcasting, in particular to a method for receiving dual-channel satellite navigation differential data, a receiver and a storage medium. Background technique [0002] Satellite navigation technology uses satellite positioning to determine its own position and uses known map information for navigation. The accuracy of the general satellite navigation and positioning system is not high, generally between 10 meters and 100 meters, which is too large for navigation and the user experience is very poor. In order to improve the positioning accuracy, it is necessary to use differential data, which can enhance the positioning accuracy, so that the positioning can be accurate to between 0.01 and 1 meter. Due to the geographical correlation of satellite navigation differential data, if the distance between the reference station providing the differential data and the receiver of the differential data is relativ...
