基于北斗导航系统并兼容GPS的渔船寻迹仪电路设计
Circuit design of Beidou satellite navigation system fishing vessels tracing instrument compatible with GPS
摘要
Abstract
In the process of the traditional fishing vessels tracing instrument positioning and tracking,it often appears defect such as tracking slow and not being easy to lock etc.,this paper puts forward the circuit design and implementation for tracking fishing traveling position trajectory instrument,it applies of domestic Beidou satellite navigation system,and is compatible with both GPS and GSM/GPRS core technology,to realize tracing and tracking of sea fishing vessels.It has the characteristics of tracing fast and tracking accurate.The results show that the positioning accuracy of tracing instrument can reach 5 m,the reacquisition time is less than 0.8 s,when the circuit power supply voltage is below 3.9 V or fishing boat speed is over 20 km/h,it will issue a warning signal.关键词
