Abstract

The embodiment of the invention provides a double-antenna BD positioning directional receiver. The defects of a GPS system and a Beidou positioning system are overcome; the double-antenna BD positioning directional receiver can be flexibly selected by a user as a peripheral accessory; the purchasing pressure of the user is reduced; the use threshold of the Beidou system is reduced; the civil process of the Beidou system can be promoted; the Beidou system is promoted to give play to social benefits of itself earlier, so the requirements of national safety and economic and social development forthe satellite navigation system are met, national informatization construction and economic development mode conversion can be promoted, and the invention plays an important role in achieving socialbenefits and economic benefits of the satellite navigation industry.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a dual-antenna BD positioning and directional receiver and its usage method. Background technique [0002] At present, the navigation systems that can be used in China mainly include the GPS (Global Satellite Positioning and Navigation System) of the United States and the Beidou Satellite Navigation System (BEIDOU (COMPASS) Navigation Satellite System) independently developed by my country. Among them, the GPS system has the advantages of high positioning accuracy and wide coverage. However, because the system is controlled by the military of other countries, it will artificially increase its positioning error or make it invalid under certain circumstances. In addition, the terminal products using GPS only have one-way reception. The ability to locate information lacks interactive communication between terminals and systems. The Beidou satellite navigation syste...
