The invention concerns an enhanced system for the stabilization of an object with reference to a moving platform. The invention is in particular suitable for the stabilization of a shipborne optical search sensor. The system comprises a stabilization platform and a regulator. According to the invention, the regulator calculates control signals for the stabilization platform on the basis of a combination of absolute ship's angular position signals and signals produced by rate gyro systems mounted on the stabilization platform. Thus, disturbances caused by flexure of the ship's structure and the stabilization platform are effectively compensated for. Said signals are preferably combined by frequency-dependent weighting.
