指北平台惯导导航系统的解算

作业内容：
一、数据说明：
1：惯导系统为指北方位的平台系统。初始经纬度为116度、39.9度,高度为500米。匀速飞行，速度为200米/秒，飞行高度不变。
2：fw中为500秒的数据，陀螺仪和加速度计采样周期为0.1秒。
3：初始姿态角为[0 0 0]（俯仰，横滚，航向）,fw中保存的为比力信息f、陀螺仪角速率信息w，排列顺序为 一~三行分别为东、北、天向信息.
4: 航向角以逆时针为正。
二、作业要求：
1：可使用 MATLAB语言编程，用MATLAB编程时可使用如下形式的语句读取数据：load D:\...文件路径...\fw,便可得到比力信息和陀螺仪角速率信息。
2：作出其位置坐标曲线图附在文本文档中。
3：以上文件以源程序和文本文档形式交，在文本文档报告中要写流程图和学习小结，写明联系方式以便联系。作业建文件夹，文件夹名写上姓名和学号。

the contents of homework
一，the explain of dates
1,inertial navigation system is flat roof system which point to the north. 
initialization of latitude and longitude is 116 degree,39.9degree,altitude is 
500 meters , velocity and altitude is not invariant.
2,fw are dates of 500 seconds ,the sampling periods gyro and accelerometer is
0.1 second.
3,initialization attitude is [0 0 0](pitching angle,roll angle,course angle)
fw contains the information of force f of accelerometer, angle velocity information of gyro w,
the arrange order from one to three row is east ,north, head.
4, anticlockwise of course angle is positive.
二，demands of homework
1,you can use  MATLAB language program .if you use MATLAB language program,reading the dates in following format:load D:\...文件路径...\fw,you can get the information of force and angle velocity information of gyro .
2,gaving position coordinate curve in text document.
3,  the homework is gaving  in form of source program and text document .in text document there are needing flow chart and studing summary.give you contact manner,and establish a file,the name of file is you name and you student number
