Abstract

A PRESENTE INVENÇÃO REFERE-SE A UM DE SENSOR DE ACELERÓMETRO DE VECTOR DUPLO (DAVS). O DITO DISPOSITIVO COMPREENDE DOIS ACELERÓMETROS TRI-AXIAIS E UM HIDROFONE INTEGRADO NUMA UNIDADE. TAL DISPOSITIVO É ÚTIL PARA MEDIR E MELHORAR A EFICIÊNCIA DE METODOLOGIAS USADAS PARA REALIZAR LEVANTAMENTOS ACÚSTICOS GEOFÍSICOS NO MAR. O SEU TAMANHO REDUZIDO E COMPACTO PERMITE UMA INTEGRAÇÃO MAIS FÁCIL COM OS VEÍCULOS SUBMARINOS AUTÓNOMOS (AUVS) E, CONSEQUENTEMENTE FACILITA A MANOBRABILIDADE DO VEÍCULO EM COMPARAÇÃO COM OS ARRANJOS REBOCADOS CLÁSSICOS. POR CONSEGUINTE, OUTRO OBJECTO DA PRESENTE INVENÇÃO REFERE-SE A (AUVS) COMPREENDENDO O DISPOSITIVO DAVS DA PRESENTE INVENÇÃO PARA ADQUIRIR E MONITORIZAR DADOS SÍSMICOS SUBAQUÁTICOS.THIS INVENTION REFERS TO A DOUBLE VECTOR ACCELEROMETER SENSOR (DAVS). Said device comprises two tri-axial accelerometers and a hydrophone integrated into one unit. SUCH A DEVICE IS USEFUL FOR MEASURING AND IMPROVING THE EFFICIENCY OF METHODOLOGIES USED TO CARRY OUT GEOPHYSICAL ACOUSTIC SURVEYS AT SEA. Its small and compact size allows for easier integration with autonomous submarine vehicles (AUVS) and therefore facilitates the maneuverability of the vehicle compared to the classic towed arrangements. THEREFORE, ANY OTHER OBJECT OF THIS INVENTION REFERS TO (AUVS) UNDERSTANDING THE DAVS DEVICE OF THIS INVENTION TO ACQUIRE AND MONITOR UNDERWATER Seismic Data.
