ABSTRACT:
The present technical solution provided allows it to determine true meridian of any movable object. This solution is based on determining true meridian by zero value of linear acceleration induced created by changing the projection of the vector of linear velocity, caused by rotating any heavenly body, in particular, the terrestrial globe. The determination is implemented in compact variant only by the devices located on the movable object without any necessity of using induced radiations, quickly and accurately without any necessity of knowing the coordinates of location and the speed of movement irrespective of weather conditions, transverse accelerations, temperature changes and external magnetic fields influence.
