Abstract (English):
The threat of a collision with a potentially hazardous object (PHO) and smaller asteroids requires the ability to reliably calculate the orbits of celestial bodies. The quality of the determined orbit depends on both the accuracy and intervals of observations and on the method of their processing: the completeness of the dynamic model, the method of numerical integration, calculation errors, etc. The practical implementation of the orbit determination algorithm is associated with the peculiarities of taking into account the above factors. To assess the accuracy of motion prediction using orbits obtained with the help of different software packages, we compared the deviations in observed and calculated values of observations, i.e.
