I suspect this is just your way of getting a lot of folks riled-up....
But, sorry to disappoint....this really isn't that big of an issue for most...
--- Yes, just about everyone does use GPS as their primary position fixing source....
And while most (myself included) have many back-up GPS units and separate power sources/supplies for them, should the GPS and GLONASS satellite
constellations fail (VERY unlikely) and/or the GPS signals jammed (possible in small geographic locations).....
Most coastal sailors should be okay (as they can do coastal piloting and DR, taking bearings accordingly, whether visual and/or radio bearings...)
And even most offshore
sailors will still be okay (as even without a sextant/almanac/tables, most offshore
sailors will have the positions either plotted on a paper charts
and/or written in their log, etc. so they can still do DR, and reach the other side of the ocean and/or find land/islands....)
--- And FYI I thought you may want to know that most offshore sailors do NOT rely on chartplotters, PC's, iPads, etc...(the internet
postings of a few, notwithstanding!!)
Coastal sailors, day sailors, bay sailors....yes, there are many that use iPad's, etc. as their primary charting/plotting source, etc...
But, not offshore sailors....(again, no matter what 'ya read on-line....most offshore sailors do NOT rely on such products for navigation
2) My direct answers, specific to your question...
With one difference, I do the same / have done the same, as Ann does, for many decades....(and yes, I started decades before GPS was launched...)

The only difference is my paper charts are my primary charting w/ GPS fixes plotted regularly, on paper charts...(along with a running DR log, as a "comparison"... to see how good I am on predicting avg. COG, current
E-series plotters and Navionics
charts are nice to look at, but are secondary...
An accurate, deviated compass
....a wrist watch...and some paper charts will still get you to where you're going!!
3) And, Wotname, for clarity....the entire Omega system has been off-the-air for over a decade now (mid-late 90's, I think)....

I assume you know that....but just wanted everyone to be aware....
I started this posting >12 hours ago....and now there are 6 pages!!!
Goodness, you guys are certainly social / verbose today!!
Oh, well....my answers still stand!!
I hope this answers your questions / adds something to your discussion..
