The combined method for observations and the modified model of observation reduction are described. We present the methods for the estimation of the coordinate accuracy of coordinates which were obtained with the use of the modified model of observation reduction. The accuracy of observations of the NEOs during their approaches to the Earth for distances from 0.009 to 0.045 AU is estimated.
