A method is disclosed where acoustic pulses are used to calculate the velocity of the medium. The inventive aspect of the invention is that the acoustic velocity may be calculated without initially knowing the separation distance between the source and the distant receivers. The method utilizes established geometrical relationships which may be solved to produce the velocity. The velocity is often used to calculate the separation distances between the desired points.

A method for calculating an unknown separation distance between a first pint and at least three points located at fixed intervals along a substantially straight line, comprising the steps of: a. measuring a travel time of an acoustic signal between the first point and each of the three points located along the line; b. calculating an acoustic velocity of the acoustic signal using a relationship between the fixed interval and the travel times of the acoustic signal from the first point to each of the three points; and c. calculating the product of the calculated acoustic velocity and the travel time between the first point and each of the three points to determine the unknown separation distance between the first point and each of the three points along the line.
