stand in error

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.
