Abstract

The invention discloses a method for designing a bilateral compensation structure-based strapdown inertial navigation attitude coning compensation algorithm. In allusion to the problem that the strapdown inertial navigation attitude algorithms at present are low in efficiency when compensating coning errors and maneuver errors at the same time, a novel bilateral coning compensation structure is disclosed; after that, the transformational relation and constrained relation from the traditional uncompressed attitude coning compensation structure coefficient to the novel bilateral coning compensation structure coefficient are established, and the error description on the basis of the traditional uncompressed attitude coning compensation structure under common maneuver conditions is deduced; on the basis, a novel attitude coning compensation structure coefficient optimization design method is disclosed and the optimization design of the attitude coning compensation structure coefficient is implemented, so that a bilateral compensation structure-based strapdown inertial navigation attitude coning compensation algorithm which is capable of effectively compensating the coning error and the maneuver error is designed.

Description

technical field [0001] The invention relates to a design method of a strapdown inertial navigation attitude solution cone compensation algorithm, which mainly includes a cone compensation algorithm structure and a structural parameter optimization method, and belongs to the technical field of inertial navigation. Background technique [0002] Since the concept of strapdown inertial navigation system was proposed in the late 1950s, after nearly 60 years of development, strapdown inertial navigation system has been widely used in aerospace, national defense, transportation and other fields. One of the main technologies that the high-precision strapdown inertial navigation system relies on is the high-precision strapdown inertial navigation algorithm, among which the strapdown inertial navigation attitude algorithm is the core of this technology. [0003] In the mid-to-late 1960s, Savage and Jordan successively proposed a strapdown inertial navigation attitude algorithm with a ...
