We're about to be hit with a solar storm... 4

[Sparweb]

Must admit I am keeping the GNSS page open during the cruise as soon as the sats drop below 4 it gets turned off.

Where the heck do you fly, the arctic circle? I'm pretty remote but I've never seen less than 7 sats (most of our Dash 8's use Universal 1Ew and the Beech are always full of Garmin GTNs).

Its the jamming and spoofing that we are watching for, before Ukraine I didn't.

I can post up the position pages for people to have a look at if you want on a typical flight and one when we are getting jammed.

Turkey, Cyprus, Israel all are pretty much jammed and within 200 NM of the Russian Border is also extensively jammed.

The spoofing seems to be around St Peterburg and a few other places

Scientist warns more powerful solar eruptions could hit Earth in 2025 - and cause the worst geomagnetic storm in 165 years

https://www.dailymail.co.uk/science...-cause-worst-geomagnetic-storm-165-years.html

An excerpt from the above item:

While Earth mostly succeeded in weathering last weekend's strong solar storm, experts have warned more powerful eruptions could continue to strike until 2025.

A Harvard astrophysicist told DailyMail.com that the sun has not yet reached its 'solar maximum,' the most energetic point of its recurring, 11-year solar cycle, in which greater turbulence raises the sun's total energy output.

That 'maximum' will finally come in the heat of the summer next year: July 2025.

'We could easily get much bigger storms over the next year or two,' Dr. Jonathan McDowell told DailyMail.com.

Oh, you fly there.

Jamming seems to come from Kaliningrad

Sorry to hijack your thread John. I'll stop.

I wonder what the astroinertial navigation system on the SR71 would cost today. It sounds like we may need it for commercial aircraft.

 

[TugboatEng]

John, I suggest you study "Meltwater Pulse 1a" to get a better understanding of how much influence the Sun has on our climate. There have been times were sea level rise has been 100x faster than it is today and that's within modern human history (less than 12000 years ago).

Tug we have inertia reference system for nav as well. Which you can see the tab for on the pictures I posted.

They are laser gyro these days. The SR71 inertia nav I suspect needed a forklift to move about.

It was being used as the secondary reference system with the Radio nav being the primary in DME/DME mode in the second jammed photo.

In GNSS mode we get around 0.01 Nm accuracy. In RNAV DME/DME its 0.1 Nm. In VOR/DME mode around 0.5 Nm.

The inertia system has drift so the accuracy changes over time and the latitude we are flying at. It starts more accurate than the RNAV and then gets less than it after about 3 hours.

I will add this to give some confidence that aircraft aren't going to fall out of the sky or start pointing in a strange direction during these events either natural with the solar storms or due human interference.

I know when that little star lights up it will be during a 2 week long cloudy spate.

I'm only 20km away from 3708m (12,165ft) elevation. Clouds here are usually lower.
Maybe you could get friendly with, or charter a local IFR airplane owner. Low wing config.

I'm not exactly sure if this is a good, or a bad omen. Anybody have an astrologer handy?
Should I start a thread in hobbies?

Jupiter in alignment with Mars? Astrology is not my bag, but I seem to recall something about peace guiding the planets and love steering the stars.

For many, this indicates that we're entering the 'Age of Aquarius':

Btw I have had so many interesting news items popped up in my news feed which I suspect is liked to this thread and others.

My first thought with the planets aligning was that's going to screw with compass variation...

Age of Aquarius. Been there. Done that, but I think the world needs a repeat right about now. ☮

And has been known for how many years in advance, that this happens in this day and age? One thing it does influence the most is weather and climate.

 

[Alistair_Heaton]

They will know about it.

If they bother to put it into the GPS database who knows.

The ground based systems are referenced magnetic north. And it's mag headings off air traffic.

As everyone will have the same it won't matter.

Maybe slightly off a desired geo track if required.
