| Abstract: | We analyzed the law of space-time change of systematic errors by a large number of measured data.We also demonstrated the existence of the residual error of systematic errors of double difference observation considering space-time relevance.The result of the experiments indicates that it can effectively improve the accuracy of separation of small deformation by taking away the residual error. |
