Abstract

Un método para determinar una orientación de un sistema de adquisición de datos desplegado sobre el fondo marino incluye medir campos magnéticos horizontales utilizando detectores en el sistema de adquisición de datos mientras que la adquisición de datos rota y desciende al fondo marino o se eleva del fondo marino. Los campos magnéticos horizontales en reposo se miden cuando el sistema de adquisición de datos está sobre el fondo marino. La dirección del sistema de adquisición de datos sobre el fondo marino puede determinarse en base a los campos magnéticos horizontales máximo y mínimo medidos durante el descenso y en los campos magnéticos horizontales en reposo.
