| Abstract: | It is unavoidable that the model errors exist in the adjustment system which is established with geodetic data to analyze crustal deformation because the mathematical and physical relationship between observations and the undetermined parameters is incompletely expressed in the established functional model.In this model,the formula of mean square error with weight to estimate model deviation is derived in detail.Both the method of distinguishing model error and that of determining the magnitude of priori co variance are put forward and then method of model error compensation of the adjustment system with the least squares collocation is suggested. Finally,the steps to process the model errors existing in two kinds of adjustment systems are suggested. |
