The determination of the trajectory of Chelyabinsk bolide according to thevideo records is performed and the results of the simulation of the fragmentmotion in the atmosphere are showed including its state at that moment. Themethods of distortion compensation and adjusting of the video images with thecalibration images and the iterative method of the trajectory improvement byazimuths and altitudes are developed. These methods allow improving theprecision of the trajectory tracing to the hundreds of meters in space and tothe tens of arc minutes in the angular measure.
