一种地磁导航算法的硬件设计与实现
Hardware design and implementation of a geomagnetic navigation algorithm
摘要
Abstract
This paper discusses a high-precision geomagnetic navigation algorithm based on interpolation matching and completes the hardware design and implementation of the algorithm.The geomagnetic navigation module relies on the spatial distribution characteris-tics of the geomagnetic field for positioning,but traditional algorithms are susceptible to noise and errors in complex environments,leading to insufficient positioning accuracy.To address this,the paper combines an interpolation matching algorithm to construct a refined geomagnetic intensity distribution model,enabling efficient processing and precise matching of geomagnetic field information.Additionally,a low-power,high-performance hardware architecture is designed to facilitate rapid execution of the algorithm.This design significantly improves the speed and energy efficiency of positioning calculations while maintaining high positioning accuracy in complex environments.It can be widely applied in modern navigation devices,providing an efficient geomagnetic navigation solution.关键词
