Embodiment Construction

[0019] The present invention will be further described below in conjunction with specific embodiments and drawings.

[0020] Such as figure 1 As shown, the Beidou positioning system of the present invention includes a battery, a step-down circuit, a step-up circuit, a control module, a receiving antenna, a Beidou module, and a data upload module. The battery supplies power to the control module through the step-down circuit, and the battery supplies power to the Beidou module after the step-up circuit. The receiving antenna is connected with the Beidou module. The Beidou module is connected with the control module. The control module is connected with the data upload module.

[0021] The receiving antenna is a high-gain patch module antenna. Through the impedance matching of the PCB circuit board, the module antenna is directly connected to the PCB circuit board, which greatly reduces the impact of impedance mismatch on signal reception, and the gain of the module antenna is grea...

Abstract

The invention discloses a control method of a Beidou positioning system. According to the control method, during detection of the system, the system enters a next step to acquire positioning information of a native machine when detecting more than two satellites only, and therefore, the positioning accuracy of the Beidou positioning system can be greatly improved.

Description

Technical field [0001] The invention relates to the technical field of signal processing, and more specifically to a control method of the Beidou positioning system. Background technique [0002] The Beidou positioning system is a positioning system independently developed by my country. At present, the Beidou positioning system has 16 satellites in orbit. As of December 27, 2012, the official version of my country's Beidou positioning system space signal interface control document has been announced. Beidou positioning and navigation The business officially provides passive positioning, navigation and timing services to the Asia-Pacific region. The system can provide positioning services for common vehicles such as automobiles, passenger planes and ships, and positioning and navigation services for precision guided weapons. It is of great significance to the military and national defense undertakings to get rid of the dependence on foreign GPS systems, and is also useful for agri...
