Abstract

The invention relates to a method for measuring and transmitting the course reference of a carrier aircraft. The method for measuring and transmitting the aircraft course reference provided by the present invention can measure the course angle of the aircraft through an external measuring device, optimize the alignment algorithm, simplify the alignment process, improve the accuracy of rapid alignment, shorten the alignment time, and meet the rapid response requirements of the battlefield. The invention also relates to a system for measuring and transmitting the course reference of the carrier aircraft.

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 problems existing in the above-mentioned prior art, the purpose...
