摘要:
为了解决简易北斗导航定位接收系统因地理位置的不同而导致测量误差不稳定的问题,设计了一种基于 STM32的简易北斗导航定位系统的优化测量方法。 其硬件设备主要包括 STM32 芯片、BD-ATGM332D-5N-3X 模块、LCD12864模块,共同构建简易卫星接收、定位、显示系统的方案;软件设计主要包含导航模块与单片机电路连接原理、系统工作流程、LCD12864 显示模块程序、校正算法介绍等。 文中利用所处地理位置影响因素不同,通过加权平均进行补偿计算,并且采用最小二乘法减小误差。 通过实验证明,该系统相对于传统的北斗导航工具,经度误差由 0. 43% 降至 0. 30% ,纬度误差由 0. 14% 降至 0. 08% 。 该方法具有更好的稳定性,能够减小因地理位置的影响造成的误差。 具有简单实用、经济成本低、便于操作等优点。
Abstract:
In order to solve the problem of unstable measurement error of a simple Beidou navigation and positioning receiving system due to different geographical locations,we design an optimized measurement method for the simple Beidou navigation and positioning system based on STM32. Its hardware equipment mainly includes STM32 chip,BD-ATGM332D-5N-3X module,LCD12864 module,building a simple satellite receiving, positioning and display system. The software design mainly includes the principle of navigation module and single-chip circuit connection,system workflow,LCD12864 display module procedures,introduction to correction algorithms, etc. We use the different factors of geographic location to compensate by weighted average,and adopt the least square method to reduce the error.Experiments have proved that compared with the traditional Beidou navigation tool,this system shows that the longitude error is reduced from 0. 43% to 0. 30% ,and the latitude error is reduced from 0. 14% to 0. 08% . The proposed method has better stability and can reduce the error caused by the influence of geographic location,with the advantages of simplicity,practicality,low economic cost and easy operation.
