基于WSN的“GPS原理与应用”在线教学实践系统的设计与应用

摘要

深入分析“GPS原理与应用”教学实践现状,针对传统GPS施测及RTK应用教学实践过程的薄弱环节,结合当前移动定位服务的发展前景,基于无线传感器网络技术,开发并实现“GPS原理与应用”在线教学实践系统平台,以引导学生进行GPS定位信息的实时接收、远程传输、动态显示、实时监测及统计分析等功能.应用结果表明,相对于传统的实践教学手段,基于WSN的“GPS原理与应用”在线教学实践系统对促进GPS实践教学具有充分的理论依据和实践意义.%Through in-depth analysis on the present situation of the teaching practice of GPS principle and application,in view of the weak link of the traditional GPS application and RTK application teaching practice process,combined with the current development of mobile location services,based on Wireless Sensors Networks technology,this paper develops and implements an online practice teaching system of GPS principles and applications,to guide students of GPS positioning information to receive real-time,remote transmission,dynamic display,real-time monitoring and statistical analysis functions.The application result shows that,compared with the traditional practice teaching methods,the online practice teaching system of GPS principles and applications base on WSN has a sufficient theoretical basis and practical significance for the promotion of GPS practice teaching.
