GROUND NAVIGATION EQUIPMENT Russian patent published in 2025 - IPC G01C23/00 

FIELD: navigation equipment.

SUBSTANCE: invention relates to navigation equipment and represents equipment for ground navigation of a moving surface vehicle. Result is achieved by introducing into ground navigation equipment a movement timer, a stop timer, a movement time adder, a stop time adder and a unit for determining the systematic component of the drift speed.

EFFECT: invention is aimed at increasing the accuracy of determining the azimuth of the current direction of the vehicle and the coordinates of its location by calculating, during the parking of the vehicle, the accumulated heading error due to the drift of the gyroscope from the heading system, as well as the values of the gyroscope drift velocity systematic component by calculating the drift velocity average value for the parking time and subsequent corresponding directional angle correction during the movement.
