摘　　要：为克服航海日志和纸海图进行船舶航迹记录的缺点,本文基于STC89C58芯片设计一种经济实用的小型GPS船舶航迹仪,能够完整、准确的记录船舶的大量航行数据,且具有船舶航行必备的导航功能。该航迹仪主要由STC89C58单片机、GPS模块、存储器、TFT彩屏显示模块、串口通信接口、按键模块和电源模块组成,以Gstar-GS-15C作为GPS数据信息接收器。硬件系统的总功耗仅为85 m A,所测船舶经度和纬度数据标准偏差分别小于0.03 s和0.136 s。经调试,本文所设计的航迹仪在功能和测量精度上均满足使用要求。To overcome the shortcomings of logbook and paper chart in recording the voyage data of ships,this paper designed a kind of economical and practical portable GPS voyage data recorder based on chip STC89C58. The designed recorder can record the abundant voyage data of ships integrally and accurately and bas the necessary navigating function for ships. The designed recorder is composed of chip STC89C58,a GPS module,a memorizer,a TFT color display,serial communication interface,keypress module and power module. The Gstar- GS- 15 C was chosen as the receptor of GPS data. The total power consumption of the hardware system was as small as 85 m A,the standard deviation of the measured data of longitude and latitude is smaller than 0. 03 second and 0. 136 second separately. After debugging,the track plotter is satisfied with the application requirements in function and measuring accuracy.
