METHOD OF INCREASING POSITIONING ACCURACY OF TERRESTRIAL MOBILE OBJECT AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC G01C21/00 

FIELD: physics.

SUBSTANCE: count from the last known coordinates obtained by processing signals from the satellite navigation system and/or signals from the reference means is carried out, the parameters of the object movement are measured, and geographic coordinates are calculated. The device includes a path sensor, a course and location control unit, a digital path model storage unit, a height sensor above the sea level, a control and display unit, a computing unit. In the initial state, from the control and display unit to the computing block, the initial data corresponding to the coordinates of the moving object at the beginning of the movement and the initial value of the directional angle are recorded in the computing unit and, in the course of its movement, the path sensor, the course and the position control unit and the height sensor above the sea level generate signals about the current values of the increment of the traversed path, the control angle and altitude above the sea level, in the computing unit, solutions of direct geodetic problems are processed by the decision algorithm, the current coordinate values are determined, the path matching coefficients and the course angle correction values for the coordinate pairs are determined, and the pair correction and averaging field are compared with the digital path model, and the final coordinate value is formed.

EFFECT: expansion of functional capabilities and higher accuracy of determining coordinates.
