随着定位技术的不断发展，各种定位技术层出不穷。但这些定位技术大多以视距通信为基础。短波通信最大的优势就是超视距通信。围绕短波能够超视距通信的优点，将短波天波通信路径近似为抛物线，并以电离层虚高是精确测量值为基础，通过求解已知点与未知点之间的距离，来定位未知点的坐标。

With the continuous development of location technology,emerge in an endless stream of various positioning technology. But these location technologies based mostly on line-of-sight communications. The biggest advantage of short-wave communication is over-the-horizon communication. In this paper,focusing on features of shortwave to over-the-horizon communication,the short-wave communication path for parabolic approximation .And with the precise measurement of ionosphere virtual height is based. Through the design of a way to calculate the distance between known and unknown point, calculate the coordinates of unknown points.
