Abstract: 
We investigated factors affecting the deviation of the local solar time of an ascending node of sun-synchronous orbits. We derived the relations for calculation of amendment to the basic inclination, which minimizes this deviation in the range of operation of the spacecraft in orbit. The use of the amendment will minimize or eliminate the orbit corrections. The theoretical results are confirmed by observations of the actual flights of the “Ocean-O” and “Egyptsat-1” spacecrafts developed by the Yangel Yuzhnoye State Design Bureau.
