sun_position
一个相当好用的matlab函数,由美国国家可再生能源实验室科研人员设计,可以计算太阳的直射维度和方位角。只要输入时间、观测地点即可。 (This algorithm is based on numerical approximation of the exact equations.
The authors of the original paper state that this algorithm should be
precise at+/- 0.0003 degrees. I have compared it to NOAA solar table
(http://www.srrb.noaa.gov/highlights/sunrise/azel.html) and to USNO solar
table (http://aa.usno.navy.mil/data/docs/AltAz.html) and found very good
correspondance (up to the precision of those tables), except for large
zenith angle, where the refraction by the atmosphere is significant
(difference of about 1 degree). Note that in this code the correction
for refraction in the atmosphere as been implemented for a temperature
of 10C (283 kelvins) and a pressure of 1010 mbar. See the subfunction
un_topocentric_zenith_angle_calculation� for a possible modification
to explicitely model the effect of temperature and pressure as describe
in Reda & Andreas (2003). )

exp1
捷联惯导系统放置在室内测试台上做静态测试,测试时间4500s。
1)取前180数据做粗对准(解析对准法);
2)取第181s~900s数据做精对准(Kalman滤波法);
3)从第901s开始做纯惯导解算;
4)用国军标的导航系统位置精度评价方法评估系统定位精度(分别计算CEP50 和 CEP95 下的定位精度)。(The strapdown inertial navigation system was placed on the indoor test bench for static test with a test time of 4500s.
1) take the first 180 data for rough alignment (analytical alignment method);
2) accurate alignment of 181s-900s data (Kalman filtering method);
3) pure inertial navigation solution is performed from 901s;
4) the positioning accuracy of the navigation system is evaluated by the method of position accuracy evaluation of the national military standard (the positioning accuracy under CEP50 and CEP95 are calculated respectively).)
