Abstract: The paper adopts cloud computing technology to solve the information source error caused by environmental impact on the sky polarization pattern and the error generated by the carrier’s own measurement to improve the accuracy and practicality of biomimetic polarization navigation. Provide a cloud computing support system for error analysis of multiple navigation units based on biomimetic polarization navigation single body angle measurement error; Based on the information provided by the multi navigation unit cloud computing structure, determine the spatiotemporal resolution model of polarization pattern maps under different information source error conditions; Cloud computing technology is used to analyze and study the measurement error of multiple cells that meet the signal source error range in the time-space region, which can effectively assist the multi unit system of polarization navigation in high-speed operation, and improve the precision and practicability of bionic polarization navigation.
