Abstract

The invention discloses a method for measuring and analyzing the measurement error of a biomimetic polarized navigation carrier. The method comprises the following steps: (1) arranging a plurality of carriers in a preset area, obtaining the relative azimuth angles between carriers, and taking the relative azimuth angles as the baseline of measuring true value of biomimetic polarized navigation carriers; (2) subjecting each carrier to t-th power azimuth angle measurement and calculation to obtain a set of measured azimuth angle values; (3) changing the preset area, rearranging the carriers, and repeating the step (2) to obtain another set of measured azimuth angle values; (4) repeating step (3) for several times, then calculating the data obtained in the step (2) and (3) to obtain the statistic error (L'kjt) of each carrier; (5) calculating the statistic error (L'kjt) obtained in the step (4), separating the random errors and instrument errors, and evaluating the error of the biomimetic polarized navigation carrier according to the error parameter values of random errors and instrument errors. The provided method can complete large and complicated calculation task high efficiently.

Description

technical field [0001] The invention relates to a method for analyzing the measurement error of a polarized light carrier, in particular to a method for analyzing the measurement error of a bionic polarization navigation carrier based on cloud computing. Background technique [0002] Traditional navigation methods are relatively mature, such as inertial navigation, satellite navigation, geomagnetic navigation, etc., but new navigation methods and methods are still emerging, and bionic polarization navigation is one of them. Bionic polarization navigation is a novel navigation method, but because the sky polarization pattern map it relies on is greatly affected by the environment, and the sensor for obtaining sky polarization direction information needs to be further improved, so it has not yet developed in application Up to now, it is only in the stage of theoretical research and experiment. [0003] Analyzing the error sources of the bionic polarization navigation experime...
