Problems solved by technology

The bionic polarization navigation is greatly affected by the environment because the sky polarization pattern map it relies on is greatly affected by the environment. At the same time, the sensor for obtaining the sky polarization direction information needs to be further improved. experimental stage
[0003] In bionic polarization navigation, errors are mainly information source errors and carrier measurement errors. Information source errors are mainly caused by changes in sky polarization patterns over time and space. Although it only accounts for about 10% of the total, because it is the application basis of polarization navigation, it has a fundamental impact on navigation accuracy. Therefore, in bionic polarization navigation, how to use effective means to control information source errors is an urgent need. a problem solved

Embodiment Construction

[0050] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0051] The cloud computing control method of the influence of the sky mode diagram on the accuracy of bionic polarization navigation of the present invention comprises the following steps:

[0052] 1) The change of the sky polarization pattern map with space will cause information source errors, so it is necessary to determine the diameter of the ground surface moving unit. The measured information source error caused by the change of the sky polarization pattern map is within the set error value δ (information If the source error is δ, then the azimuth error of the earth’s surface is 10δ), the specific steps include (such as figure 1 shown):

[0053] ①Randomly distribute the monomer position

[0054] On a circular surface with a diameter of d (for example, the initial test diameter d is set to 5 meters, but not limited to this), N (such as 100, but...

Abstract

The invention relates to a cloud computing control method for bionic polarization navigation accuracy influences by a sky mode pattern. The cloud computing control method comprises the following steps: (1) determining the diameter of a region in which a ground motion single body is positioned when measuring that an information source error caused by the change of a sky polarization mode pattern is in a set error value delta range; and (2) determining the time intervals of measuring when measuring that the information source error caused by the change of the sky polarization mode pattern is in the set error value delta range. The cloud computing control method adopts a cloud system to carry out hierarchy operation to execute and monitor all the steps in the whole process of the technical scheme; manual interferences are not needed; the errors of manual operation can be reduced and huge and complicated operation tasks can also be efficiently finished; the rapidness and the accuracy of the calculation are guaranteed.

Description

technical field [0001] The invention relates to a method for controlling the accuracy of bionic polarization navigation, in particular to a cloud computing control method for the influence of a sky model map on the accuracy of bionic polarization navigation. Background technique [0002] Human beings currently have many navigation methods, such as satellite navigation, inertial navigation, geomagnetic navigation, etc., and new navigation methods and methods are still emerging, such as bionic polarization navigation is one of them. The bionic polarization navigation is greatly affected by the environment because the sky polarization pattern map it relies on is greatly affected by the environment. At the same time, the sensor for obtaining the sky polarization direction information needs to be further improved. experimental stage. [0003] In bionic polarization navigation, errors are mainly information source errors and carrier measurement errors. Information source errors a...
