说明

这是2023年由Scott Manley发布的一部讲解，主题归在Space exploration & spaceflight。它讲的是gps这一支里的具体问题，而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成：Scott Manley covers how GPS works and how civilian accuracy went from a planned 100 meters to about one meter. He explains the technology and the removal of restrictions that made this possible.这些读者给出的理由，核心是：Recommended as a solid history and explanation of GPS, especially when GPS outages or accuracy come up.讲法不绑某一条新闻，过几年仍然可以当材料看。从2023年到2025年，有3位不同的读者在3个不同月份把它推荐出来，其中明确叫别人去看的有1次。适合用一集把一个概念补上的人。抓住它用的那个图像或类比，比背公式重要。如果已经会了基本定义，就把注意力放在它怎么把gps变成能跟着复述的例子。
