把激光陀螺捷联惯导系统和GNSS接收机固联于实验车实验仓中，接收机天线固联在实验车实验仓上方，车载计算机实时接收和采集惯导系统、卫星导航接收机的原始数据，在郊外开阔公路进行车载实验。 通过matlab编程实现卫星导航伪距单点定位、INS/GPS松组合导航的全过程。 1）卫星导航单点定位测速：利用采集得到的接收机时间、伪距、多普勒频移数据，要求进行单点定位、测速解算，输出接收机的位置、速度随时间的变化曲线，并给出位置、速度误差曲线； 2）松组合导航：结合惯导解算和卫星接收机单点定位测速，要求采用Kalman滤波器实现惯导/卫星位置、速度组合导航解算，滤波器维数至少包括惯导的位置、速度、姿态角9维。将组合导航后的姿态角与纯惯导的姿态角进行对比分析，给出位置、速度误差曲线。(The laser gyro strapdown inertial navigation system and GNSS receiver are fixed in the experimental compartment of the experimental vehicle. The antenna of the receiver is fixed above the experimental compartment of the experimental vehicle. The on-board computer receives and collects the original data of the inertial navigation system and satellite navigation receiver in real time, and carries out on-board experiments on the suburban open highway.)

matlab界面设计的一些资料笔记,可以做为初学者参考用(matlab interface design some of the information notes, can be used as reference for beginners)

目的：实现多gui间的通信。 1. 由gui1打开gui2，并从gui2读取数据画图； 2. 数据包的传递：在gui1定义一个数据包，包括字符串，数据，把数据包传递给gui2并由其更新，gui2更新好的数据在传回gui1并显示出来。（注：程序中加黑划线部分为实现预期功能的要点） (Purpose: communication gui. Method: 1. Opened by gui1 gui2, and to read data from gui2 drawing (2) the transfer of the packet: a packet defined in gui1, including strings, data packets passed to gui2 updated by gui2 the updated data in the returned gui1 and displayed. (Note: the program plus the the black underlined part to achieve the desired functionality of the points))
