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

The first Galileo test satellite, the GIOVE-A, was launched 28 December 2005, while the first satellite to be part of the operational system was launched on 21 October 2011. As of July 2018, 26 of the planned 30 active satellites are in orbit.[9][10] Galileo started offering Early Operational Capability (EOC) on 15 December 2016,[1] providing initial services with a weak signal, and is expected to reach Full Operational Capability (FOC) in 2019.[11] The complete 30-satellite Galileo system (24 operational and 6 active spares) is expected by 2020.[12] It is expected that the next generation of satellites will begin to become operational by 2025 to replace older equipment. Older systems can then be used for backup capabilities.

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.

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.

In all of these systems, ground infrastructure is required to measure each satellite's ephemeris and update the navigation system with this information. Left to itself, navigational accuracy would degrade over a period of days to weeks until the system failed.
