| 摘要: |
| 分析了重力异常产生的原因，根据有害加速度对于惯导系统的影响，建立了基于重力
异常的惯导比力误差方程及姿态误差测量模型。结合航行试验分析了影响与应用效果，试验
结果表明，高精度的姿态测量系统中必须考虑重力异常的影响，利用该方法可以基本消除重
力异常的影响，部分海域可使惯导姿态精度提高约20″，对提高航天测量船外测精度具有重
要意义。 |

| Abstract: |
| The cause of gravity anomaly is analysed. Specific INS(Inertial Navigation Syste
m) force e
quation and attitude error model are proposed based on harmful acceleratio
n caused by gravity anomaly.The effect is discussed through sailing test and the
result shows the influence of gravity anomaly must be considered in high precis
ion attitud
e measurement system,this method can effectively eli
minate its influence, the INS attitude precision can be improved about 20″
at some sea area.It is significant for improving the exterior ballistic measurem
ent precision of
the space tracking,telemetering and command(TT&C) ship. |
| Key words: space TT&C ship inertial navigation system(INS) attitude precision gravity anomaly compensation method |
