error analysis of coal self-ignition in columned experiment stand
圆柱型煤自然发火实验台的误差分析
In the forest stand whose crown closure is under 0.5, the average value of mean square error is 0.502m, distributed between 0 to 0.7m and the frequency is 82.8% and the frequency whose mean square error is under 1m is 91.4%.
在郁闭度小于0.5林分中,平均中误差为0.502m,集中分布在0~0.7m范围内,频率为82.8%,中误差小于1m的频率为91.4%。
The direct computation method used to estimate attitude parameter is introduced, then the integer ambiguity is resolved by utilizing Z-transformation augmented FASF algorithm. At last, the software flow of attitude determination system in which stand-alone position error is compensated and the experiment result are presented.
介绍GPS姿态测量系统的直接计算法,然后采用Z变换增强FASF算法求解载波相位整周模糊值,最后给出了采用补偿单点定位误差的GPS姿态测量系统的系统流程和计算机实验结果。
