GPS L1信号的仿真及信号的捕获 画信号频谱及相关捕获图(GPS LI signal simulation and acquisition)

GPS 单点定位，高度角随机模型加权，电离层K8模型改正。(GPS single point positioning, elevation weighted random model, ionosphere corrections K8 model.)

將經緯度資料轉換為AIS之AIVDM的NMEA語句，並輸出至串列埠。(Arduino program for translate Latitude and Longitude data into AIVDM NMEA phrase.)

采用c语言编写的用于GSM模块的发短信程序(Texting program using c language for GSM module)

lambda algorithm for gps attitude determination

说明：  用于将GPS传送的信号以一定的采样速率离散化，方便以后进行FFT运算(GPS signals used to transmit a certain discrete sampling rate, FFT operation to facilitate a later)

说明：  十进制到十六进制转换的程序。程序要求从键盘取得一个十进制数，然后把该数以十六进制的形式在屏幕上显示出来。(Decimal to hex conversion program. Procedural requirements to obtain a decimal number from the keyboard, and then the hexadecimal number to be displayed on the screen.)

GPS/SINS松组合导航源代码，搞组合导航的可以参考(it is good for learning GPS and INS)
