Flying your UAV (a.k.a. drone) in GPS mode? Use K-Index monitor to see if it's safe to do so!

K-index sits in the background of your phone/tablet and gives an alerts if high levels of solar activity are generating geomagnetic storms - potentially disrupting GPS reception.

If you do not like to run this app all the time, then please have a look at K-Index lite.

---------------------

The K-index quantifies disturbances in the horizontal component of earth's magnetic field with an integer in the range 0-9 with 1 being calm and 5 or more indicating a geomagnetic storm.

The Estimated 3-hour Planetary Kp-index is derived at the NOAA Space Weather Prediction Center using data from the following ground-based magnetometers: Sitka, Alaska; Meanook, Canada; Ottawa, Canada; Fredericksburg, Virginia; Hartland, UK; Wingst, Germany; Niemegk, Germany; and Canberra, Australia. These data are made available thanks to the cooperative efforts between SWPC and data providers around the world, which currently includes the U.S. Geological Survey, Natural Resources Canada (NRCAN), the British Geological Survey, the German Research Centre for Geosciences (GFZ), and Geoscience Australia. Important magnetometer observations are also contributed by the Institute de Physique du Globe de Paris and the Korean Space Weather Center.

K-Index monitor will check the value every 1/2 hour and show the K-index in the devices notification bar.

The 1/2 hour update can be bypassed when tapping the K-Index value in the running process screen.

0, 1, 2 and 3 are shown in green and okay.

4 is yellow and maybe still okay.

5 and above are red, and not advisable to use a GPS device as GPS satellites might be affected!
