极区海图基准和导航误差控制理论及其应用研究

The shipping, energy and military value of the Arctic area is increasingly prominent. Solving the problem of polar navigation is of great significance for ensuring the safety activities of the carrier in polar region. However, the special geographical location and harsh climatic conditions in polar region bring great challenges to the safety and precise location of ships in polar area, and put forward higher requirements for polar navigation. The project will set up a new algorithm and a new model for the projection of nautical chart in the polar region based on the earth ellipsoid model through the mathematical analysis with strict analytical significance, which is based on the theory of polar region projection and the control method of navigation error; Meanwhile, the polar region navigation coordinate system will be redefined based on the Gauss projection square net; On this basis, the network of error control will be designed for use in the new coordinate system, further reforming and improving the theory and algorithm of polar navigation system; And based on the new projection system and coordinate, the theoretical research on the theory of polar route planning and track drawing will be carried out. The above research will systematically solve the problem that the previous chart projection method and the navigation algorithm are difficult to adapt to the requirements of the polar navigation, and provide support for the safe navigation of the carrier in the polar region.

北极地区的航运、能源和军事价值日益凸显，解决极区导航问题对保证载体在极区的安全活动具有重要的意义。然而极区特殊的地理位置和恶劣的气候条件给舰船极区航行安全和精确定位带来了巨大挑战，对极区航海导航提出了更高要求。本项目以极区投影理论和导航误差控制方法为研究对象，通过具有严格解析意义的数学分析，建立基于地球椭球体模型的极区海图投影新算法和新模型；基于高斯投影方里网对极区导航坐标系进行重新定义；基于重新定义的极区坐标系研究极区导航误差控制技术,设计适用于新坐标系的误差控制网络，进一步革新和完善极区导航理论和算法体系；并在新的投影体系和坐标系的基础上开展极区航线规划和航迹绘算理论研究，系统解决以往海图投影方式和导航算法难以适应极区航海导航需求的问题，为载体在极地地区的安全航行提供保障。
