1. A method for continuous localization of streamers towed by a vessel including at least one onboard acoustic controller, each of said streamers comprising: geophysical data sensors; acoustic means for measuring distance from at least one adjacent streamer; means for the absolute localization of said streamers, wherein the method comprises: at least one step for the generation, by said acoustic controller, of an acoustic cycle determining sequences of acoustic sending and receiving between said distance-measuring acoustic means, at least one step for defining a series of at least two distinct acoustic cycles, each acoustic cycle being suited to a theoretical geometry representing the shape of said streamers; at least one step for determining the real geometry of said streamers; at least one step for detecting a change in real geometry followed by a step for generating a new acoustic cycle, selected from among the series of the at least two distinct acoustic cycles defined during said step for defining, said new acoustic cycle being adapted to said change in real geometry.
