we are digressing rather spectacularly here - but hey, why notYour point self explains why technology and equipment is important. GPS satellites are equipped with atomic clocks to be precise. They don't do that with after market chips and they can't do that with after market chips. For time to be precisely synchronized among devices, almost all devices on internet or cellular devices are synchronised to global time servers (which are synced to reference clocks) which can calculate time more precisely than after market chips. Normal day to day devices have tendency to drift time calculation as clocks are not precise and one can easily observe the drifts, no fancy equipment needed here. So it means that good equipment is neccessary everywhere where precision is needed.
The moot point here being this :
- Your low grade device running on super noisy power can still calculate your precise position on a body as large as the earth
- And it does this simply by factoring in the ultra miniscule difference of the time that it takes for a few signals to reach you from their respective satellites
- In other words, it is multilaterating on the basis of the time stamp differences of very precise signals reaching you at the speed of light - from objects that are barely a few thousand kms apart
So if could posit that the precision of these digital signals could be easily altered by electrical nasties (I love this phrase) either in terms of accuracy or time drift.
And thus pretty much nothing based on digital signalling would work today, let along something that is working at the level of extreme precision required for this example.
After all, the clean , precise unaltered signal from the transport (satellite) is going for processing into the nasty cheap noisy phone on planet earth for the final output -
and thus should be subject to time domain drift or jitter or corrupting noise from the electrical nasties while passing through the output chain that sits on a Micromax device charging on the alternator of a Bajaj Auto Tempo, isn’t it?
