The method for the estimation of the corrections to the fundamental catalogue equinox and equator has been developed using the combined radar and optical data of near-Earth asteroids. The corrections tothe zero-point FK5 based on the processing of about 6000 radar and optical observations of ten near-Earth asteroids almost for sixty years time interval have been obtained.
The analysis of parameters obtained and comparison with the results of other researchers revealed that the zero-point of the FK5 was in need of small correction.
