Description

technical field [0001] The invention belongs to the technical field of polarized light navigation, and more particularly relates to a transfer alignment system assisted by polarized light navigation. Background technique [0002] Polarized light navigation is a new type of navigation. Its original prototype is a polarized light compass made by the ancients using natural minerals (calcite, potassium feldspar, etc.). One of the available navigation devices. In recent decades, scientists have used the principle of animal bionics to develop polarized light navigation instruments with more complete and excellent performance. When the navigator is combined with inertial navigation and GNSS satellite navigation, it has a certain degree of orientation and positioning capabilities. [0003] Cutting-edge research results show that the accuracy of polarized light navigation sensors is better than 0.1°, and the north-finding accuracy after combining with inertial navigation can reach ±...

Problems solved by technology

[0004] However, in the transfer alignment process of the above scheme, the misalignment angle error between the main inertial navigation of the aircraft and the sub-inertial navigation of the air-launched aircraft must be controlled at about 1°. The air-launched aircraft includes various types of aircraft launched from the aircraft, etc. That is, the initial state of the air-launched aircraft on the aircraft can only be launched in the direction of the nose. Taking the aircraft’s backward-launched aircraft as an example, it can only be launched forward and then turned 180°, which not only delays the reflection time and consumes more fuel. , and the guidance and control are very complex and difficult
