Considering the impact of these tests, that doesn’t seem likely. You wouldn’t be sending covert messages in a way that would be so heavily scrutinized. I know it was a theory presented during the video, but that’s just journalistic integrity.

And ultimately, even if they were covert messages, now they also know they can disrupt gps

I thought that was the cover story. They deliberately used a channel partially in the bandwidth for some deniability. It isn't like they didn't know what bandwidth GPS used when they designed the satellite.

Yes, that's the video I watched. Good stuff.

GPS satellites send at like 25W of power. Naively I would think you could make that 2.5kW on a satellite without issues, probably even more.

You have to get ones that used to be at rest areas and stuff that are comically large and impractical to use in a car. Much less try to fold.

Store the maps in a laptop case so people think you are breaking out the pc.

Also I love maps and as a kid, in the 80s I had maps of just about everywhere, I collected park maps from all the places I hiked and had geological survey maps of the state I lived in. I kept all the maps in the back of my Datsun 510 station wagon. I got lost very often when driving but I would pull over a dig through the maps till I figured out where I was. I did have one of those big roll up maps that you see in old schools, where you could pull it down and it would roll itself back up, but it from the 40s and it's Africa so there is not any real information on it but it was fun to haul it out un roll it and say " nah I don't think that's it" and let it flap around as it rolls up.

I went looking for an image of my map, and found one. https://oldnewhouse.com/products/vintage-classroom-pull-down-map-of-africa-2196?srsltid=AfmBOoqDLztG46dLMq7Eh-hPMAtz0SEnlpnpdGQUu4GIuE5qwMe7MnqT

My map doesn't look as nice because someone kept it in the back of a Datsun station wagon and used it as a joke prop.

I have two sets of these that I use. When one of them's for when I'm off road and off-grid and very little works. The other one so that way I can have my kids look at just general road atlases as we travel quite a bit they enjoy seeing and trying to find where we're at. They will come in handy in case of anything happening as far as connectivity and stuff like that.

Looks up Here in the map index... D3 sees this side of the map starts at 13, flips map over, finds D and 3, looks up and slams on brakes before rear ending an even more lost pedestrian.

"You should watch where you're driving," my passenger says before their eyes return to their phone.

Honks horn, pedestrian is startled out of examining their map, gives a sheepish wave of apology and speeds off. Return to map, notice there's a big traffic jam on the intended route, turn down a side street instead, thanking map for helping.

Getting your timing source through fiber is definitely the best way to go, as long as you have a backup timing source OTA like GPS and other GNSS in case the fiber gets cut.

I mean, he did say he sold out to private equity cause he wanted to retire basically. His channel is basically now his retirement investment

You do know that you can block channels, right?

Why?

“GPS” would mean GNSS satellite systems like GPS, as well as terrestrial systems like AGPS and base-station-based triangulation. Given that modern train control systems involve transponders alongside the railway line, these can be used as well. Railway lines running through tunnels in particular would rely on non-satellite systems.
