Research on high-latitude transfer alignment technology

The Arctic Circle is rich in resources and has huge economic potential. Since the 21st century, its strategic position has become increasingly prominent. The development and utilization of the polar region has become the focus of attention of all countries. The transfer alignment of the polar high latitude sea area is a comprehensive technology, which mainly involves three technical issues: shipborne inertial navigation polar area navigation technology, shipborne inertial navigation mode switching technology, high latitude moving base transfer alignment matching Technology. Solving the transfer alignment of missile-ships in high-latitude seas in polar regions will greatly improve the adaptability of my country’s underwater vehicles in the Arctic. Inertial navigation system transfer alignment technology and other key technologies are focused on research. Aiming at the problems of complicated navigation parameter conversion in the polar navigation application of inertial navigation system of the existing lateral coordinate system and difficulty in information cross-linking between different navigation systems, a new method based on The grid unified the transfer alignment method of the polar earth ellipsoid model, and the grid transfer alignment was simulated and verified. The simulation showed that the transfer alignment algorithm is correct, the content is comprehensive, and the verification of key technical approaches is feasible.
