简介：地球作为triaxial被花僵硬身体，它在欧几里得的空格自由地旋转。开始的方程是Euler动态方程，与比比C的B和esmaller小的A。Euler方程被解决，并且数字结果被提供。在计算，下列参数被使用：(C~B)/A=0.00327353；(B-A)/C=0.00002196；(C-A)/e=0.00329549，并且地球的旋转的吝啬的尖速度，co=0.00007292115rad/s。计算证明除地球和它的旋转的免费Euler行列的自我旋转以外，那在那里存在免费点头：在theEarth的片刻的旋转轴和周期性地随着时间变化的吝啬的轴之间的点头角度，或角度。免费点头被调查。

简介：评价详细基于GPS答案的IGSSINEXfile被讨论的地球自转参数(ERP)的方法。有估计ERP的二个不同方法：一个人是参数转变方法，并且其它是有限制条件的直接调整方法。由把估计的结果与独立版权节目作比较到IERS结果，全身的错误能与GPS观察在估计的ERP被发现的剩余。

简介：为旋转的一个新奇算法当旋转角度的波动的范围在这个区域以内是有限的时，不变的模板匹配被建议[−20°，20°]。匹配的候选人用低费用改进了的一个计算联盟者被选择关联算法。“并且”操作被采用减少计算费用。因此，算法过量地改进匹配的速度。模拟结果验证建议方法的效率。而且当引用图象的尺寸被修理时，这个节省时间的算法的优点作为实时图象的尺寸的增加更明显。建议方法的匹配的速度比分解的二水平的金字塔的速度快超过20倍加速方法。
