针对相位率值的特点,引入抗差最小二乘估计进行速度计算,根据IGGⅢ方案选取合适的等价权因子来降低存在小周跳影响的观测值对结果的贡献,利用航空飞行实验的数据进行了计算分析,结果表明经过抗差后的速度仍可保持在mm/s的量级。 更多还原

【Abstract】 Aiming at the characteristic of the phase rate observation,calculated the carrier velocity by using the robust least square estimation,choosing the equivalent weight by IGGⅢ principle to lower the contribution of the observation that contain the gross error which is smaller than 1 cycle.By Calculating and analyzing the data acquired from a experiment of aviation flying,the result shows that the accuracy magnitude of velocity can keep on mm/s after RLS estimation. 更多还原
