Abstract

Un método para determinar las posiciones de los cables marinos de sensor geofísico que incluye remolcar cables marinos separados lateralmente en una relación relativa entre los mismos por paravanes próximos a sus extremos frontales. Los cables marinos incluyen transmisores acústicos separados y receptores acústicos. Los paravanes cada uno incluye un transmisor o receptor acústico. Las señales se envían desde los transmisores acústicos y se reciben en los receptores acústicos. Las señales de posición geodésica se detectan en cada paraván. Las identidades de los transmisores de las señales acústicas recibidas se determinan para determinar los tiempos de recorrido de las señales acústicas recibidas. Los tiempos de recorrido se convierten en distancias entre los transmisores y los receptores identificados. Las posiciones relativas de los cables marinos se determinan desde las distancias. Las posiciones relativas de los cables marinos se combinan con las señales de posición geodésica detectadas para determinar las posiciones geodésicas de los cables marinos.
