# KP 指数与地磁暴

> 当前和预报的行星 KP 指数，上限由你设定：高值会干扰无人机的 GPS 精度和指南针。

**免费**

*最后更新: 2026-10-14*

**KP 指数** 以 0 到 9 的等级衡量地球的地磁活动。地磁暴期间，GPS 定位精度下降、指南针读数变得不可靠：无人机悬停时可能漂移，或者要求校准指南针。

Drone Weather Forecast 显示来自 GFZ 波茨坦的 **当前及预报 KP 值**，并与你设定的上限比较。一旦 KP 超过上限，结论就会提醒你。

指南 [无人机飞手的 KP 指数](https://droneweatherforecast.app/zh-hans/guides/kp-index-for-drone-pilots) 介绍了这个等级，以及地磁暴天气该怎么做。
