中文摘要:
      采用传统高度差原理,整理归纳了天体真高度、天体恒星格林时角与赤纬和天文船位的解算模型,使用C#编程工具,设计出天文定位绘算系统,并进行了误差分析.该系统经过实际航海应用和软件测试,将自动计算结果与手工计算进行比对,可知该系统计算迅速、结果准确,能够满足航海要求,并且避免了在最通常情况下手工计算所不可避免的误差或错误,证明了系统的实用性和可靠性.
英文摘要:
      By using C sharp tool to design the automatic calculation system of navigation astronomical orientation, base on altitude difference principle, and arithmetic models of aster true altitude, aster Greenwich hour angle, aster declination and ship position, were arranyed. After the practical application and software testing, in comparison with the hand-worked calculation, it concluded that this system enables the rapid calculation and reliable results, thus meeting the needs of navigation and avoiding the errors or mistakes that causing by hand-worked calculation. Thus the results prove its the practicability and reliability.
