求三点定位算法或者库

[just1]

已知三个经纬点及点至目标点的距离，求目标点的经纬度。有这样的算法或者库吗库的话最好要 python

@realpg 高一不会很累，没事就折腾

先学解析几何再折腾

@imn1 估计学完我就没时间折腾了😣

数学专业方面的问题推荐在 Mathematics Stack Exchange 中提问，比较专业，不过你的问题要描述清楚。这个 GPS 定位算法很复杂的。而且通常并不是用软件实现的，而是在 GPS 芯片内部实现的。只是研究者可以通过用算法实现来模拟，像 Software-defined Radio(SDR)（软件定义无线电）一样，这种叫 Software-Defined GNSS Receivers
