Well, when there's a reason, and it's thought out properly, there's nothing wrong with a goto.
"'Do what thou wilt...' is to bid Stars to shine, Vines to bear grapes, Water to seek its level; man is the only being in Nature that has striven to set himself at odds with himself."
What I meant was that C++ overloads breakitself, although I suppose this can be debated. But it's annoying not to be able to exit a loop using break when inside a switch statement that's embedded within that loop.
Gallileo is emerging as an alternative to GSM. Being a newer implementation of the same working principle, they provide higher precision.
I have nowhere close to an understanding of how Gallileo (/GSM) positioning works. So when a collague of mine claimed that a precision of one meter on earth requires that the position of the satellites are determined with a precision of one meter (or preferaby better). If you are triangulating between three signals, and some astronauts were out there and pushed each of the three satellites one meter to the south, your Gallileo (/GSM) reading would be 1 meter wrong.
From simle high school geometry, this argument sounds very plausible. But is it really true, that meter and sub-meter precision location is dependent on a similar precision positioning of the satellites?
(Obviously, if you have signals from several satellites, you may do some smoothing to correct for a single off-position satellite. The question is whether the precision of the positioning directly depends on the satellite positioning, on the same scale.)
You are asking about the Gallileo positioning system, I presume?
The European Union has an agency called the European GNSS Agency[^]. The satellite network was set up by the European Space Agency in cooperation with the EU, but ESA is a separate organization, not tied to the EU, and I don't know if they have any sort of ownership to Gallileo.
As far as I (partly, and probably wrong) understand it, it is more the way the signal speed, how long it takes to get from the satellites to your device with a precise clock, that will determine the precision of the position.
But hey, nothing prevent you to google it.
I'd rather be phishing!
