To performing positioning of survey equipment, measurements of acoustic signals reflected from at least one boundary of a marine environment are received. The reflected acoustic signals are reflected from the at least one boundary in response to acoustic signaling originated by an acoustic source. A positioning model is updated based on the measurements of the acoustic signals, wherein the positioning model contains information relating to positions of components of a positioning system that includes the acoustic source and acoustic receiver.
