Removal of GLONASS support in Apple Watch Ultra 4 The Apple Watch Ultra 4 has officially dropped support for GLONASS, a satellite navigation system.

This change means that the Ultra 4 will now rely solely on GPS, Galileo, QZSS, and Beidou for location tracking.

While GLONASS was previously included in the Ultra 3, its removal may enhance the watch's accuracy and battery life by streamlining the navigation process.

Apple has not provided a specific reason for this decision, but it reflects a focus on optimizing performance in their latest wearable technology.

And again, imagine we're in the middle of the ocean or we're in that wide open prairie, so you really have a horizon to horizon view.

Today, there will be, because there is GPS, there is Galileo, there is, uh, BeiDou, and there is GLONASS.

If you're tracking all of those satellites, you will pretty easily see about 35 satellites at a time, um, like from that horizon to horizon.

And each of those satellites will be providing open signals that you can make measurements on, uh, to probably three frequencies.

Now, we have very advanced systems like the Aegis and other systems aboard vessels and also land-based systems that can do some things, but So far, they haven't struck a vessel, probably because their GPS has been struggling to work properly, most likely not by accident.

But once their GPS is able to work properly, let's say they use the Chinese, uh, global, the GNSS system that China has, BeiDou, they might be able to get past our GPS interference, right? So there's a real threat here that hypersonics could actually hit a vessel, and even if they didn't do it purposely, if they did hit a vessel even by accident, we're talking about a problem.

Doesn't have to kill anybody, it just has to strike, because then, then suddenly their level of competence is perceived to be much higher than we thought it was, which is again another problem we had in February when we thought their level of competence and sustainability was lower than we thought it was, or it was higher than we thought it was, and we had the war, and we saw, like, that wasn't true.

So they're gonna probably try more of these hypersonic strikes.

You have Galileo, which is the European system.

And you have Beidou, which is the Chinese system.

People generally say that the Chinese system is the best because, in fact, it's very new.

It's,
