摘要
结合国内外在GPS发展领域的研究现状,对GPS动态导航数据处理中需要注意的问题进行了综合分析.通过分析提取的GPS信号,得到GPS动态导航数据处理过程中定位数据的存在不稳定性的结论,针对实际情况设计出简单可行的滤波算法,将真实的GPS定位信息从各种干扰中实时最优的估计出来.在对处理过的数据进行深入分析的基础上,通过数学建模和相关实验设计出简单可行的GPS自动导航控制算法.在程序优化设计上,利用系统时钟来控制转动角度的大小,大大提高了整个软件系统的工作效率.测试结果证明采用的方法基本可以满足要求,移动平台通过GPS自动导航可以顺利到达所设置的目标点.
After deep research on the development of GPS and the dynamic navigation technology,a solution of the design was using the GPS navigation technology in the water quality testing.The whole design explain that the dates in the dynamic navigation were instability.According to the practical situation,made the design of Filter Algorithm.Deal with the useful GPS data and design a variety of algorithm for GPS auto-navigation control by the way of the mat model.Select the algorithm not only simple but also to meet the technical requirements of the algorithm,so as to achieve the goal of self-positioning and navigation.On designing and optimizing to programs,used the system clock to control the size of the rotation angle.Through practical experiments and tests,the design meet the basic requirements,GPS navigation successfully reached the target set point.
