摘要
随着航运业的发展,复杂的内部结构对船舶上的日常工作以及应急反应的要求变高。目前采用的一些导航算法存在精度低、误更新等问题。为了有效解决问题,本文首先对船舶步行导航系统的特征进行介绍,对行人步行导航系统中的惯性导航算法进行相应简化;然后,设计基于船舶室内导航系统简要技术架构并给出改进的导航算法,以此来实现对船舶上导航系统中的惯性导航算法的误差进行补偿。其后仿真结果表明,该算法可解决传统零速更新算法中存在的误更新问题,将其运用在船舶室内导航系统中,能够提升船舶应急反应能力以及位置服务的要求。
Along with the development of the shipping industry,complex internal structure makes the requirements of daily work as well as emergency response on the ship becomes high. Currently,some navigation algorithm is faced with low accuracy,misuse updates and other issues. To solve the problem effectively,firstly,ship pedestrians of the pedestrian navigation system features were introduced,and pedestrian navigation system of the inertial navigation algorithm is simplified accordingly; Later,a brief technical architecture and improved navigation algorithm based on ship indoor navigation system is given which is aimed to make up errors of the inertial navigation algorithm in ship navigation system. After comparing the simulation,the results show that the algorithm can solve erroneous update problems in traditional zero speed update algorithm,it is possible to enhance the ship's emergency response capacity and location of the service request when used in indoor navigation systems of ships.
