| Abstract: | We design a set of processing methods for navigation data of offshore towed streamer exploration.Firstly,we introduce the key technologies of preprocessing,such as gross error detecting of crossline acoustics observation and detecting the problems of RGPS which likes cyclic slip.Then,we present the processing methods through three aspects which are constrained network adjustment,curve integration,and stable adjustment.Also,we establishe the constraint equations and give the strategy of weight fixing.We also give the results compared with the software used commonly aboard to proved validities of the whole processing methods. |

| Keywords: | gross adjustment curve integration towed streamer exploration navigation |
