It sure would be great if members of the forum had a fixed thread that this type of solar information could be posted to so we could all be notified ... or is there a place that you all look at everyday and I just don't know it?

¡Looking forward to it thanks!

There is already an app. It's called Solar Monitor.......notifies you of any activity with phone alerts. I refer to it regularly if I am considering flying with GPS.

For monitoring before flight I use Solar activity on google store it is simple and effective. https://play.google.com/store/apps/details?id=org.ligi.solar_activity_monitor&hl=en It use the source from NOAA.gov

Great! You gonna charge and arm and leg for it, or just an arm?:friendly_wink:

It will be available for the low low price of just a few fingers. ;-)

You are correct, and that's a great app. What we are building is actually something more of a flight companion app that will include space weather reports as just one feature of a larger feature set.

[MENTION=6734]gtranquilla[/MENTION]; I do not know how to read the charts you started this thread with; is there a link to an explanation of the graphs?. It sure would be good to understand which site or application works the best and use that for our planning. I work our in the field a lot, as a scientist, and I have seen bogus GPS coordinates on occasion - I wonder if this was the reason.

[MENTION=132]Kilby[/MENTION]; what is the ETA of your app?

RadioActive
In nearly all cases the satellites are not affected by solar activity but the earth's atmosphere is..... and that is the main problem with GPS as explained here:
http://gauss.gge.unb.ca/gpsworld/gpsworld.july00.pdf
Time is so critical for GPS position accuracy that the GPS Satellites are equipped with atomic clocks.
But even that is not enough during intense solar disturbances to the earth's atmosphere as the radio signals from each satellite are refracted differently at some times. A slight change in signal direction also affects signal speed etc.

The information was helpful, technical, and well written. The formulas are a bit detailed but I just read past that part - Thanks

There is an App for that.
Solar Activity Monitor along with Magnetic Field Detector for Android.
I don't know how accurate they are but they seem to work and at least do what they say they will.
That's more then you get d=from DJI sometimes. :tennis:

I'm hoping to get it submitted to Apple for review before the end of the year, so less than 2 months.
