By simulating the geomagnetic fields and analyzing thevariation of intensities. this paper presents a model for calculating the objective function ofan Autonomous Underwater Vehicle (AUV)geomagnetic navigation task. By investigating the biologically inspired strategies. the AUV successfullyreachesthe destination duringgeomagnetic navigation without using the priori geomagnetic map. https://countryscenesaddleryandpetsuppliers.shop/product-category/bit/
