Research And Development Of Marine Beidou Positioning Signal Acquisition Module Based On SCM

In today's fast-growing shipping industry,ship navigation system is also facing innovation generation,the traditional gyro compass,log and other equipment function can be realized through satellite navigation system,and satellite navigation system has become an indispensable part of the modern ship navigation.With the completion of China's BeiDou navigation system and further improved,will provide a more independent,more secure,more innovative choices for ship navigation.The use of domestic ship navigator is generally dominated by GPS,and the application of Beidou system navigator with high price,large volume,complicated operation,used to replace the original GPS system cost is too high,and not conducive to the popularity of Beidou navigation.In this article,the design and development of marine BeiDou signal acquisition module based on SCM as the main content,focus on "BeiDou navigation",the hot spots,using SCM as the controller,Designed a BDS-GPS dual-mode positioning data collection and display Modules.It realizes the extension and complement of the original ships navigator,which not only save the cost,but also improve efficiency.In the hardware section,using a microcontroller 12C5A60S2 by Hongjing Technology Co.,Ltd.as the main controller,using TD3017 A type BDS-GPS dual-mode chip by TaiDou Microelectronics Co.,Ltd.and active antenna,with the 12864 LCD module,developed the marine BeiDou signal acquisition module.The module has a small size,low cost,fast signal acquisition and good stability.It implements the ship's time service,Positioning,Speed and course monitoring,and other functions.It also can realize multiple functions such as map location display by connecting with the other terminal.It provides a new choice of time service and Positioning and other services for Ship Navigation.
