Portable Beidou satellite timing device

Abstract

The invention relates to a portable Beidou satellite timing device comprising a Beidou antenna module, a Beidou information processing module, an interface conversion module, a power module and an interface module. The modules are assembled into a USB-flash-disk-type housing cavity. The Beidou antenna module is used for receiving a Beidou satellite signal; the output terminal of the Beidou antenna module is connected to the input terminal fo the Beidou information processing module; the output / input terminal of the Beidou information processing module is connected to the input / output terminal of the interface module by the interface conversion module; and connection with a user device is realized by the interface module. Compared with the prior art, the portable Beidou satellite timing device has characteristics of high integration degree, high portability and interface universality, ultra low power consumption, high precision, and microminiaturization; the application range of the timing equipment is extended; the user cost is lowered; and adaptability to time using equipment is improved.

Description

technical field [0001] The content of the present invention belongs to the technical field of satellite navigation application equipment, and relates to a portable Beidou satellite timing equipment. Background technique [0002] The Beidou satellite navigation system is a global satellite navigation system independently developed by my country. The system officially provides passive positioning, navigation and timing services to the Asia-Pacific region since December 27, 2012. With the development of Beidou satellite navigation technology, Beidou terminal equipment is also developing in the direction of multi-function, high precision, and high integration. It has been widely used in hydrological forecasting, fishing boat monitoring, forest fire prevention and other fields. [0003] At present, the existing Beidou satellite timing equipment on the market mainly includes Beidou timing user machines and Beidou digital display clocks. Output the calculated time information thro...

Problems solved by technology

However, in the actual use environment, all kinds of timing products on the market present many shortcomings and inconveniences. The main shortcomings summarized in the process of use are as follows: 1) The traditional timing equipment is large in size and adopts a split design 1. The antenna and the host are connected by radio frequency cables. During use and installation, special places, carriers (such as fixed cabinets, etc.) and tools are required, which cannot meet the timing requirements in sudden on-site or fast-moving environments; 2 ) In terms of interconnection and intercommunication with external devices, the existing devices need to use serial port communication. The serial port cable connection requires that the device must have a serial port and cannot interact with other devices, which has certain limitations on the use environment. Meet the needs of equipment and satellite time synchronization in environments such as fast maneuvering; 3) The power consumption of existing equipment is relatively large, and the power consumption of the user machine is tens of watts, which requires high-power batteries or DC power supply, and is not suitable for field time service
