This has been discussed many many times. It's been determined that Kp index, sun spots, solar flares, etc, have zero influence on our Phantoms. It's a good theory, and it makes perfect sense, but it doesn't pan out in reality. You can make technical arguments until the cows come home, but those who have flown for years know for certain that the Kp index doesn't effect Phantoms in any way, shape, or form.
IMO airmap is a better app than hover. Hover tends to miss some TFRs which can cause big problems.
The K-index quantifies disturbances in the horizontal component of earth's magnetic field.During a major geomagnetic storm, GPS signals from the satellite to our Phantom GPS receivers get bent by the increased electron density, which increases the path length and introduces position errors. The disturbed ionosphere can also cause degraded signal-to-noise problems, meaning your receiver may loose lock on one or more birds. Also, the bending of signals can also cause "phase slips," which can also cause the receiver to temporarily loosen the GPS, taking a few seconds to relock on the satellite.
Scientific experiments done during strong geomagnetic storms show the bending of the path length to cause about 30M (100 foot) errors in position at mid-latitudes (like the US / Europe and Australia), and slightly worse near the equator.If you think that this information does not affect the positioning system of the Phantom, it is your opinion, but in commercial aviation when operating with inertial systems and other navigation systems, this value can affect the precision of the instruments. This is why navigation systems are self-corrected, based on other data from other instruments.
I do not think this happens in the system that the Phantom use.
