摘　　要：文章采用静态模拟动态的手段,研究基于精密单点定位技术实时确定海上舰船位置和姿态的方法,并分析实时精密单点定位技术的定位定姿精度。研究表明:用精密单点定位技术进行实时动态定位,一般可获得2cm的平面定位精度和4cm左右的高程精度;在动态精密单点定位技术的定位精度一定的情况下,航向角的精度高于横滚角和俯仰角;真实动态观测值的随机误差比静态模拟的大,定位和定姿精度可能会有所降低。The static observations were used to simulate dynamic observations.The real-time position and attitude of vessels on the sea were determined by using real-time Precise Point Positioning（PPP）technique,and the precision was analyzed then.The results showed that the plane precision of real-time dynamic PPP could achieve 2cm and elevation precision achieve 4cm;in the case of dynamic PPP precision determined,the precision of heading angle would be better than that of the roll angle and pitch angle.Moreover,the random error of true dynamic observations was greater than that of the static simulation observation,and the precision of positioning and attitude determination may be reduced.
