Even that the sun is about 150 Mio. kilometers far away from us those solar particles hit the earth with a speed of more than 2000 Km/sec. .
The most known effect of the solar storms are the Northern Lights (polar lights).
Normally the Earth's magnetic field protects us against solar storms. With particularly strong solar storms this magnetic field will brake and can lead to disturbances on earth.
And due to those solar storms in February 2011 the radio reception in south China was disrupted or in 1989 the power grid of Quebec City was paralyzed down.
Right now (2012) we have the strongest solar storms since 5 years. The severe phase of solar activitiy is currently still growing.
The peak will be reached approximately in 2013. The effects are not estimated yet.
These solar storms are also the GPS satellites in space exposed. In an interrupted GPS reception the exact location of course also affected. GPS-based systems can not function properly.
The Kopter cannot hold i.e. with the function PositionHold the exact position or fly to a different point with the function ComingHome or execute different other GPS-based function without any error.
To see the GPS behavior during a solar storm the Kopter was placed in an open meadow and been not moved.
The received satellite data showed now no precise position. By the incorrectly transmitted data through the satellite the GPS on the Kopter thought, that the Kopter moves.
And that with ~10m/s in a radius of ~64mtr!
This is a Widget to display the latest 3 Hourly Planetary(estimated Ap) K Indices fromhttp://www.swpc.noaa.gov/ftpdir/lists/geomag/AK.txt to e.g. help UAS Pilots to be aware of possible GPS-Problems. Read more about that here:http://www.mikrokopter.de/ucwiki/en/SunStorm
The whole APP ist OpenSource and you can find the code on https://github.com/ligi/Solar-Activity-Monitor
