DETERMINING A POSITION OF A SURVEY RECEIVER IN A BODY OF WATER

摘要

To determine a position of a survey receiver used to measure a response of a subterranean structure to a survey signal, positions of the survey receiver as the survey receiver descends in a body of water to a surface are received from an acoustic ranging system. Measurement information associated with movement of the survey receiver is received from at least one sensor. Based on the measurement information from the acoustic ranging system and the at least one sensor, the position of the survey receiver at the surface once the survey receiver has reached the surface is computed.
