GLONASS

Guardian is based around the Global Navigation Satellite System, or GNSS.

The project, to give its full name, the GNSS Upper Atmospheric Real-Time Disaster Information and Alert Network, uses the radio signals from the four navigation constellations, GPS, Galileo, BDS and GLONASS.

Name aside, the project has some really interesting goals.

Objective 1, the result of which you can see in the video or on the website, is to allow users to explore ionospheric perturbations.

This pricing model may influence user decisions regarding carrier plans and could lead to increased adoption of the feature among T-Mobile subscribers.

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.

Siri recap feature on Apple Watch The new Siri recap feature on the Apple Watch Series 12 and Ultra 4 continuously listens to conversations and generates summaries for users.

They're all separately operated and, and managed, but they are all s- very similar.

GLONASS is a little bit different in that GLONASS uses multiple frequencies like within a band, and all of the other ones, uh, use the same carrier frequency for all the measurements.

But they're, they're very, very similar in, in their design.

Yeah.

Those satellites are 20,000 kilometers away, and they don't move so quickly.

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.

It would be a massive disaster if we lost GPS.

I mean, there is Galileo and GLONASS, I guess, as well.

Yes, yes, let's all go to GLONASS.

I think that would be, yeah, well-received in our government.

In the intro call, you also mentioned a scenario that was an internal issue at Georgetown involving, I believe, a compromise of a personal laptop, elevated rights, Active Directory, that whole thing.

It's got additional signals it can use.

Your cell phone has got great anti-jamming and anti-spoofing because it's using GPS, it's using Galileo, it's using China's Baidu, it's using Russia's GLONASS, it's using all the space-based organization systems like WAAS and EGNOS.

It's taken in all of these different signals and it's saying, okay, that's a good one and that's a bad one and that's a good one.

When you've only got one signal, you can't tell if it's bad or not, right? So number one mitigation, a second signal.

All the different GNSS services.

Yeah, GLONASS.

I've got no idea what you just said.
