With the development of the economy of international and the more communication of the countries , the navigation gets a chance to have a booming future . the navigation technologies are more and more to be emphasized 随着全球经济的发展、国家之间交流的频繁,航运业迎来了蓬勃发展的又一次高峰,航海技术的提高也越来越受到重视。
Since mobile robots will be widely applied in industry , transportation , construction and aerospace in the 21st century , much higher requirements have been placed on the intelligent navigation technologies for mobile robots 在21世纪,移动机器人( mobilerobots )将在工业、交通、建筑与航天等领域发挥越来越大的作用,同时也对移动机器人的智能导航控制技术提出了更高的要求。
It ' s a pity that the colliding accidents between vessels increased year by year in spite of the continuous development of the modern navigation technology , orientation and navigation system as well as the seafarers quality 令人遗憾的是,尽管有了这一规则,在现代航海技术不断发展,定位和导航系统已非常先进,船员的素质也在不断提高的今天,船舶碰撞事故仍然连年不断发生。
Secondly , we analysis the subsystems which make up an abis , how to utilize data warehouse technology ^ data navigation technology and business modeling technology in an activity - based business intelligence , and we also discuss the 7 ways in abis implementation 本文分析探讨了基于作业的信息系统的几个构成部分和实施形式,探讨了在企业建设和实施abis若干问题,在此基础上进行了一个abis原型系统的分析和设计。
In deep space exploration missions , autonomous navigation technology is very important , and in this paper , we do some research into the autonomous navigation schemes of encountering small celestial bodies . it is mainly described as the follows : firstly , by analyzing the orbit characteristics and task requirements in encounter , the simplified orbit dynamic model for the deep space probe is built up , and whether the corresponding model error that meets the demanding of autonomous navigation task is validated 在深空探测任务中,自主导航技术是十分重要的,本文对交会小行星的自主导航方法进行研究,主要内容包括:首先,分析交会小行星的轨道特性及任务需求,建立简化的深空探测器轨道动力学模型,并验证了简化模型的误差能否满足自主导航任务的需求。
