Embodiment
[0058] The present invention has been successfully applied to Inspur Qiaojingang Beidou handsets and tablet computers. At present, the three-dimensional positioning accuracy of the Beidou navigation system is about ten meters, the P code of the GPS three-dimensional positioning accuracy is about 6m, and the C / A code is currently about 12m. After testing, on the Beidou handheld and tablet computer, the actual positioning accuracy is less than or equal to 5 meters, and the positioning effect is good.

The invention provides a differential positioning algorithm based on a Big Dipper / GPS (Global Positioning System) double-mode positioning module, which is suitable for a Big Dipper positioning system and contributes to effectively increasing the positioning accuracy of a Big Dipper module in reference to a GPS wide area differential technology based on a Big Dipper / GPS double-mode positioning module. After being applied and popularized, the differential positioning algorithm can play an important role on the aspects of military and the construction of national economy. When the differential positioning algorithm is applied to military, the intelligence reconnaissance capacity of the army of China can be raised to a new level, and the acquired information is more accurate. As for construction of national economy, the differential positioning algorithm can be applied to a plurality of fields such as vehicle navigation, scheduling of vehicles (public safety vehicles, fire protection vehicles, bank vehicles, taxies and the like), monitoring, urban transportation management, field operation and the like.
Description
technical field [0001] The invention relates to a satellite navigation positioning technology, in particular to a differential positioning algorithm based on a Beidou GPS dual-mode positioning module. Background technique [0002] Satellite navigation and positioning system is an important space infrastructure. It combines the advantages of traditional astronomical navigation and positioning and ground radio navigation and positioning. It is equivalent to a radio navigation station set in space, which can bring huge social and economic benefits. At present, only a few countries in the world can independently develop satellite navigation systems. [0003] The world's first global satellite navigation system is the GPS system implemented by the United States in 1973, which is used for both military and civilian purposes. But for a long time, the United States has only provided precise positioning signals to its own military, and provided low-precision signals with interferenc...
