mapobjects编程学习，使用mapobjects初次编程实现，感觉是一个不错的控件，对于开发gis及其有用。(Examples: design and implementation of thematic mapping systems, development, learning, initial implementation, and much criticism.)

Using wavelet denoising thought, Based on matlab GUI interface design, Simulation of the effect is very good.

GPS,单片机设计，供参考。互相学习指导(GPS, single chip design, for reference. Mutual learning guidance)

来自武汉大学导航工程专业的卫星导航算法程序设计课件，全面解析了SPP程序设计过程(The courseware of satellite navigation algorithm program design from navigation engineering specialty of Wuhan University has fully analyzed the SPP programming process.)
