Abstract: On the basis of the analysis of error sources in marine magnetic survey,different error models,which can characterize the change of the systematic errors,and their compensation models are constructed.The solution methods of compensation models are presented.Some questions involved in solving the adjustment problem,such as the choice of error model,the stability of solution of problem and the test of significance of compensation efficiency,etc.,are discussed.A practical survey data set is used as a case study to prove the efficiency and reliability of the compensation methods.
