zero-difference

In this paper, cycle slips and gross errors are detected, repaired and marked by automatic editing algorithm for zero-difference observations, and on this basis, using carrier phase smooth pseudoranges.

本文运用自动编辑算法对非差观测数据中的周跳和粗差进行探测、修复与标记，并在此基础上利用修复后的载波相位平滑伪距观测值。

Application of Robust Estimation in GPS-Based Satellite Zero-Difference Kinematic Orbit Determination

抗差估计在星载GPS卫星非差运动学定轨中的应用

The mathematic model of orbit determination of GPS satellite using zero-difference data is deduced in detail.

详细推导了利用非差伪距和非差相位确定GPS卫星轨道的数学模型；

The principles of non-contradiction, zero-difference and free space-time in law of freedom show that deviated rhetoric describes things and expresses concept regardless of the contradiction, difference, and space-time.

自由律的无矛盾、零差异和无时空的特性使变异修辞在表达观念或事物时不考虑事物之间、观念之间的矛盾和差异，也不考虑时空差异。
