Re: Spexit!
Those that are not (e.g. Falkands) are likely not supported with the required precision by Galileo, because there isn’t a high-rising MEO over that location.
OK, here we go again. As I've said before the Galileo orbits are circular, so there are no special cases because the satellites are at apogee: apogee and perigee have the same radius. Secondly we can easily compute the period of the orbits based on the orbital radius and the mass of the Earth: it's about 14h4min (50682s about). It's pretty easy to see from this that there are no privileged longitudes: all places at a given latitude see the same average number of satellites as the orbital planes move over the surface (you have to be careful to do this right: don't use the solar day). It's also easy to see from symmetry that negative latitudes are equivalent to positive ones.
So what this says, in summary is that coverage depends only on the absolute value of latitude: things work as well at any longitude, and places north of the equator get equivalent coverage to places south of it.
So, OK, what's the latitude of the Falklands? -51.56 degrees. What's the of London? +51.52 degrees.
In other words: if Galileo (or GPS: I've not done the sums for GPS but it will be the same) works well in London, it works well in the Falklands.
Please, stop bullshitting: it makes you look like a fool.
