%X The pitch and roll of vessel are measured by sensors of vessel attitude in geodetic coordinate system.With the consideration of the azimuth and pitching of theodolite from optical encoder,the position of LOS stabilization is transformed from deck coordinate system to geodetic coordinate system by usin g coordinate axis circumrotation.Angle changes are measured by optical encoder and sensors of vessel attitude in real time.The error of LOS stabilization is computed in geodetic coordinate system with the data of these changes.The error is effectively compensated by servocontrol system in order to solve the problems of LOS stabilization availably.Practical tracking experiments based on warship prove this system is of high precision in the aspect of LOS stabilization,and is powerful with excellent effect in mitigating the influence of ship-sway.
