常规的潜艇水下定位依靠惯导系统。 |
| 4. | This scheme constructs an underwater positioning system based on the combination of dgps and acoustical positioning
该方案构建了由dgps定位和水声定位相结合的水下定位系统。 |
| 5. | The technologies are emphasized , including image collection , preprocessing , edge detection and selection , calculating the dose of the point and drawing the isodose
着重探讨了系统的实现技术，包括模拟定位机下定位图像的采集、预处理、边缘识别与提取、任意点的剂量计算和等剂量曲线的绘制等。 |
| 6. | Simulations show this algorithm is effective whether the target moves or not . in chapter six , the influence for flying posture change of the observer on locating process is studied
第六章研究了观测平台的飞行姿态变化对测距定位的影响，给出了在机载观测平台发生飞行姿态变化情况下定位求解的两种思路。 |
| 7. | The main reason is as follows : dust in lifting rail is not removed clean ; lifting rail is not at a level ; the installation of low locator is not correct ; regulate screw in lifting wheel regulates too high
趟动门钰感觉不顾滑，主要原因有：吊轨里的灰尘没清除干净吊轨不够水平下定位安装不准确和吊轮调节螺丝调节过高造成。 |
| 8. | This method makes use of acoustical relative positioning technique , extending the dgps positioning technique for surface applications to underwater cases . with this positioning system , the submarine can directly get its longitude and latitude , and the positioning precision can ensure to be the same level as the surface application cases of dgps
系统采用系缆浮筏作为潜艇利用dgps进行水下定位的中继站，利用水声相对定位技术将dgps水面定位向水下延伸，使潜艇在工作潜深就可以直接获得自身的大地经纬度坐标。 |
