摘　　要：高速、高精度的划船效应补偿算法是提高捷联惯性导航系统(SINS)性能的重要环节 .研究了划船效应补偿算法和划船效应补偿误差特性 ,推导了通用划船效应补偿系数方程和误差公式 ,给出了 1 7种划船效应补偿算法 。High speed and accuracy sculling compensation algorithm plays a key role in strap-down inertial navigation system (SLNS). A research on sculling compensation algorithms and their error characteristics is made. The equations of sculling coefficients and their error characteristics is made, the equations of sculling coefficients and the equations for the error are derived first, then 17 sorts of sculling compensation algorithms are proposed. Finally the computer simulation is taken to show the character of sculling compensation errors.
