Summary

The purpose of data processing is to obtain in explicit form maximum information on the object of the data measurements. This is accomplished by the use of suitable models based on the most up-to-date knowledge of the theory of probability and mathematical statistics. The need to constantly improve models for processing data sets is stimulated by the rapid development of geodetic and geophysical measurement techniques on the one hand and the possibilities of contemporary computer techniques on the other. The reasons for the incessant improvement of mathematical models are both gnostic and economic; experiments in particular are time-consuming and expensive to prepare and carry out; moreover, they may be unique and impossible to repeat. To develop an effective method for preparing such experiments and a correct procedure for processing the results is a theoretically exacting, although least costly, part of the whole process of preparation, realization and the evaluation of the measurements. The purpose of this book is to acquaint the reader with the mathematical methods in use at present, including those being developed and applied in advanced geodetic and geophysical centres.
