天文三角形解算方法比较

Solutions for Calculating Astronomical Triangle

使用"电子海图显示与信息系统(简称ECDIS)"解算天文三角形不仅能提高天文航海计算的速度和精度,而且还可以帮助驾驶员更好地理解天体天球坐标和天体地理坐标的关系;同时使用ECDIS解算天文三角形也符合STCW公约马尼拉修正案中提倡使用天文航海计算软件的建议。本文旨在探讨使用ECDIS解算天文三角形的方法。

Using ＂Electronic chart display and information system （ECDIS）＂ to calculate astronomical triangle not only can improve the calculation speed and precision, but also make officers get easier understanding of the celestial body＇ s celestial coordinates and geographic coordinates with the help of ECDIS＇ s display function. It also comply with the advice of STCW Manila amendment that using calculation software to calculate astronomical triangle. The purpose of this study was to compare existing methods and put forward using ECDIS to calculate astronomical triangle.
