Problems solved by technology

But the time service that the GPS satellite timing device utilizes the GPS satellite system to carry out is real-time time service, and the power consumption is relatively large, and the GPS satellite system is a satellite system owned by foreign countries, and its safety and reliability are relatively poor. Therefore, it is necessary to propose a technical means, By extracting the time information of Beidou satellites, it is possible to use Beidou satellites for time service

Abstract

The invention discloses a system and method for extracting time information of a Beidou satellite based on an FPGA. The method comprises the following steps that firstly, satellite information output by a Beidou receiving machine is received by an FPGA processing unit, secondly, time of the received satellite information is extracted, so that coordinated universal time is extracted; thirdly, extracted coordinated universal time is converted into national standard time. According to the system and method, the time information of the Beidou satellite is extracted, so that the purpose that a time service is provided through the Beidou satellite is achieved.

Description

technical field [0001] The invention relates to a method and device for extracting satellite information, in particular to a system and method for extracting Beidou satellite time information based on FPGA. Background technique [0002] China's BeiDou Navigation Satellite System (BDS) is a global satellite positioning and communication system independently developed by my country. Sophisticated satellite navigation system. The system consists of a space terminal, a ground terminal and a user terminal. It can provide all kinds of users with high-precision, high-reliability positioning, navigation, and timing services all-weather and all-weather around the world, and has the ability to communicate with short messages. Regional navigation, positioning and timing capabilities, the positioning accuracy is better than 20m, and the timing accuracy is better than 100ns. [0003] At present, in terms of economy and stability, GPS satellite timing is generally used to obtain the worl...
