Abstract

En fremgangsmåte for å bestemme posisjoner av geofysiske sensorstreamere innbefattende å slepe lateralt atskilte streamere opprettholdt i relativt forhold mellom seg ved hjelp av paravaner i nærheten av sine fremre ender. Streamerne innbefatter atskilte akustiske sendere og akustiske mottakere. Paravanene innbefatter hver en akustisk sender eller mottaker. Signalene blir sendt fra de akustiske senderne og blir mottatt ved de akustiske mottakerne. Geodetiske posisjonssignaler blir detektert ved hver paravane. Identitetene til senderne av de mottatte akustiske signalene blir bestemt for å bestemme forplantningstider av de mottatte akustiske signalene. Forplantningstidene blir omformet til avstander mellom de identifiserte senderne og mottakerne.Relative posisjoner av streamerne blir bestemt fra avstandene. De relative posisjonene til streamerne blir kombinert med de detekterte geodetiske posisjonssignalene for å bestemme geodetiske posisjoner av streamerne.
