SYSTEM AND METHOD OF DETERMINING LOCATION COORDINATES Russian patent published in 2013 - IPC G01S19/42 

FIELD: radio engineering, communication.

SUBSTANCE: location coordinate values are calculated with low accuracy and if high-accuracy coordinate determination is impossible, an adjustment is made to the calculated low-accuracy values in order to determine the final coordinate values, wherein the adjustment used is the difference between calculated low-accuracy coordinate values and calculated high-accuracy coordinate values at a point in time when high-accuracy determination of location coordinate values was last possible, wherein the possibility of high-accuracy location coordinate determination is constantly checked, and if possible, coordinate values are calculated with high accuracy and the calculated adjustment is once more applied to the calculated high-accuracy coordinate values to obtain a new final location coordinate value.

EFFECT: providing smooth transition from one method of determining location coordinates to another without abrupt change in coordinate values, which ensures more reliable control of transportation vehicles and similar objects.
