1. A seismic survey system for recording seismic signals during a marine seismic survey, the system comprising:

  • first to third underwater bases, each housing at least one autonomous underwater vehicle (AUV);

    the first to third underwater bases each being connected through a corresponding cable to a corresponding buoy that is floating at the water surface;

    the first to third underwater bases each having a controller that determines its geographical location and transmits the geographical location to the at least one AUV; and

    the at least one AUV being configured to receive a pinger signal from at least two of the first to third underwater bases when traveling under water so that its trajectory is adjusted in real-time, based on the geographical locations of the at least two of the first to third underwater bases while moving toward a target position.
