You really watch the Kp index ? You are in Alaska ? Is it really something to be carefull with ? I know solarflares can disturb radio communication. But living in Norway and being Alot outdoors using Garmin GPS, I never ever had problems with positioning. But maybe drones are more sensitive.
Anyhow, if the new FW gives yo so much trouble, ever considered downgrading ?
it is difficult to know exactly, the effects on DJI products due to the closed nature of their flight control software and more importantly their filtering algorithms ..
in the military we have aggressive GPS satellite norming algorithms at are constantly computing satellite geometry, RAIM and DOP.. additionally tracking observed vs expected signal timing etc and will drop satellites from the 'solution' if they are not performing appropriately due to geomagnetic, reflective, multi-pathing, etc errors...
geomagnetic storms have been definitively shown to interfere with satellite communications and timing, and thus there are GPS implications as the GPS positioning system relies obviously on just that timing of signals from multiple satellites in known positions...
DJI drones use a combination of GPS, barro, MEMS IMU, compass, VPS sources though complimentary and kalman filters for navigation... so depending on this combining, weighting, filtering, etc of these sources vs the accuracy of the calculated navigational data really can't be analyzed since access to the raw values are not permitted in the firmware.
