Omega and Navy Navigation Satellite System have been increasing utility value in the elecronic sea navigation field. Both systems have global coverage but individual merit and demerit. The former has unrestricted user time while the latter has high position fix accuracy as merit. Contrary to this character, the former has low position fix accuracy while the latter has restricted user time as demerit. In order to correct these opposit demerits, we propose here Omega/NNSS hybrid navigation system with data processing by Kalman filtering in which Omega works as velocity sensor every two minutes. The paper describe construction of the hybrid navigation, calculation procedure of the position fix by Kalman filtering and simulation of the system assuming various noises. Results of Monte Carlo simulation showed that 50〜80% accuracy improving is feasible in proposed system compared with normal NNSS position fix method.
