摘要
为了实现声学多普勒流剖面仪(ADCP)的航海导航定位功能,提出了ADCP与光纤陀螺罗经进行组合导航的方案,研究了利用光纤陀螺罗经辅助ADCP进行导航定位的方法,分析比较了ADCP独立进行航位推算和光纤陀螺罗经辅助ADCP进行组合导航的精度。试验结果表明,光纤陀螺罗经辅助ADCP进行组合导航的定位精度至少提高1倍以上,其定位精度可以达到150m/h,能够满足航海导航定位的要求。
The paper studies and presents a fiber optic gyro compass(FOGC) aided acoustic Doppler current profile(ADCP) navigation methods. The position precision analysis was made on the ADCP independent operation mode and the FOG compass aided ADCP operation mode. The result shows that the position precision of FOGC aided ADCP mode is twice better than that of the ADCP independent mode, i.e., up to 150 m/h.
