Abstract

The invention relates to an aerial-carrier course reference measurement and transmission method. An external measuring device measures the course angle of an airplane, an alignment algorithm is optimized, an aligning process is simplified, the rapid aligning precision is improved, aligning time is shortened, and and the demand for rapid response of a combat is met. The invention also relates to anaerial-carrier course reference measurement and transmission system.

Description

technical field [0001] The invention relates to a method for measuring and transmitting the course reference of an aircraft. The invention also relates to a system for measuring and transmitting the course reference of the carrier aircraft. Background technique [0002] Before the fighter plane is dispatched to perform the mission, it needs to complete the initial alignment work. At present, the main method of alignment is to use the aircraft's own inertial navigation, and the alignment accuracy is mainly affected by the technology of the inertial navigation device and the interference of the surrounding environment. In the existing technology, the alignment accuracy is low, and the azimuth alignment takes a long time, which makes it difficult to meet the rapid response requirements of the battlefield. [0003] Therefore, prior art needs further improvement. Contents of the invention [0004] In view of the above-mentioned problems in the prior art, the purpose of the p...
