Europe Relies on American GPS as Its Own Galileo System Suffers Massive Outage 101

Posted by msmash from the how-about-that dept.
An anonymous reader shares a report: Europe's Galileo satellite network -- used by satnavs, financial institutions and more -- is in the throes of a huge outage. The system has been down since Friday meaning that travelers (and others) in Europe have instead had to fall back on the American Global Positioning System (GPS) -- or even Russia or Chinese systems. Galileo has been struck by what is being described as a "technical incident related to its ground infrastructure", and it's not clear when the situation will be remedied. The European GNSS Agency (Global Navigation Satellite Systems Agency, or GSA) says that the incident affects only the Galileo initial navigation and timing services. It stresses that "the SAR service -- used for locating and helping people in distress situations for example at sea or mountains -- is unaffected and remains operational".

        Technically? No. I bet the issue is financial. GPS is good enough for most people. It gets you where you are. So why develop a new system for the phone. That would introduce extra code and thus extra cost for basically not much extra usability.

        Lots of devices already use multiple systems. The iPhone for example can use both GPS and GLONASS. Any vendor that has designs on selling their nav products in multiple markets is going to want to use common hardware that can shift seamlessly between them whenever possible. This makes it cheaper to manufacture the device because they don't have to make and maintain multiple different bits of hardware. They can just use software to access the system(s) they are interested in for their use case. Such hardware already exists and chances are good you have some in your hand or pocket right now.

        And by most people I mean almost anybody. Those who need to have the cm precision will already be buying stuff that is able to do so.

        It's not just about accuracy though using more systems can and does improve location accuracy. It's also about redundancy and resiliency. This outage is an excellent example of why that sometimes matters.

    • Is there any technical reason we can't have receivers that use all the different systems together to get more precise locations?

      We already do exactly this and have for many years. Not just satellite systems either. We also use terrestrial based nav systems in many cases to improve accuracy. Also helps with power consumption, device size, cost, etc. Relying on multiple independent systems is in general a very good idea just in case one of the systems has an unexpected problem with service... ahem...

    • Technical reasons? Not really. It's a legal issue. From what I recall (and I may be wrong), consumer devices in the US are only legally permitted to receive satellite signals from FCC-approved satellites, so, unsurprisingly, they're not allowed to receive signals from Galileo and GLONASS because those systems—given their foreign origins—were never submitted for FCC approval. In some cases, those same devices will switch to using Galileo or GLONASS once GPS reports that they are no longer within

        When I first saw your post, I didn't believe that the US FCC would regulate a radio receiver in that fashion, because it doesn't fit my understanding of the general approach to radio regulation in the US (It is my understanding that radio receivers generally only need comply with FCC controls on spurious emissions, and do not need to be "licensed devices" as transmitters must. However, digging a bit deeper, I found this article on Galileo reception that appears to address the point you made https://galileo [galileognss.eu]

        • The article goes on to point out that many people have GLONASS receivers that work in the United States, so manufacturers might have been ignorant of (or ignored) the need for a license request before manufacturing/selling such a GLONASS receiver.

          The law does not say what you think it does. If you look at the definitions in 47CFR25.103, you'll find "earth station" does not mean "any receiver", it means:

A station located either on the Earth's surface or within the major portion of the Earth's atmosphere intended for communication: (1) With one or more space stations; or (2) With one or more stations of the same kind by means of one or more reflecting satellites or other objects in space.

          • You're assuming that "communication" is bidirectional. Is it in those regulations? It may be. I don't know. As I said in my previous post, I had read (presumably in Slashdot comments) that Galileo was off-limits to all or most US-located devices. Based on other responses I received to my above comment, it sounds like that limitation may no longer be in place, so all of this may be moot anyway, regardless of whether or not I was right to begin with (which I readily acknowledge may not be the case).

            • You're assuming that "communication" is bidirectional. Is it in those regulations?

              Yes. "Communications with" means both ways. "Communications from" is one way. The license required is because of the transmitter, not the receiver.

It's not a major technical problem, but it involves consuming a lot more power trying to get a lock on 4-8 satellites vs 8-16 satellites.

      There isn't one simply because a sufficiently accurate INS in such a small form factor is not possible yet. The offset and drift of micromechanical sensors is just too large. Drones use them for control and stability over short timescales but rely on GPS or direction finding and gravity for navigation.
