我以前在海军当过 OS（雷达航海兵），《美国实用领航员：鲍迪奇》是一本极好的参考书。
I was an OS in the Navy and The American Practical Navigator: Bowditch is a fantastic reference.
……这里有 PDF：https://www.celnav.de/page2.htm 除此之外，你显然还需要一本当年的《航海天文历》（网上能搜到 PDF），而且你可能还会想要一本：-《鲍迪奇》（美国实用领航员）。这是航海界任何方面的权威参考书，由 USCG 出版，你也可以免费下载：第 1 部分：https://thenauticalalmanac.com/2024_Bowditch-_American_Pract...…
…the PDF here: https://www.celnav.de/page2.htm Besides that, you'll obviously need a Nautical Almanac for the current year (you can find a PDF online), and you'll probably want a copy of: - Bowditch (American Practical Navigator). This is the definitive reference for anything navigation, it's published by the USCG and you can also download it for free: Part 1: https://thenauticalalmanac.com/2024_Bowditch-_American_Pract...…
在 GPS 出现前的 1980 年代，美国动力艇协会（US Power Squadron）把《美国实用领航员——航海概要（1966年版）》作为主要参考书。我祖父当年还主讲过其中一门课。亚马逊（美区）有 2002 年版本的重印本：http://www.amazon.com/The-American-Practical-Navigator-Bowdi...…
The US Power Squadron back in the pre-GPS 1980s used 'The American Practical Navigator-An Epitome of Navigation (1966)' as their primary reference book. My grandfather ran one of the courses. Amazon(US) has a reprint of the 2002 version: http://www.amazon.com/The-American-Practical-Navigator-Bowdi...…
同感：对我来说半正矢函数（haversines）挺习以为常的，因为我受过商船大副培训，我们在大圆航线（Great Circle）计算里经常用它。我现在还留着我那本泛黄的《美国实用领航员》（“鲍迪奇”），里面有一页又一页的三角函数表。
Same here: haversines seemed normal to me since I was trained as a merchant marine officer and we used them in Great Circle calculations. I still have my old copy of American Practical Navigator ("Bowditch") with pages and pages of trig tables.
> 正如《美国实用领航员》（又名“鲍迪奇”）中所说：“没有任何领航员应该完全依赖电子手段。一个总是盲目按几个按纽、读出坐标来导航的领航员……
