1. A method for determining true meridian of any object at rest comprising the following stages:

  • rotation of vessels incorporated into a sensor for measuring horizontal acceleration by means of an electric motor around a vertical of any object at rest, said vessels including pressure determination points symmetrically positioned with respect to the vertical of the object,stopping the rotation of the vessels when attaining a zero signal of linear acceleration,determining the true meridian by position of a perpendicular in a horizontal plane to an axis of sensitivity of the said sensor for measuring horizontal acceleration.
