I should also add these are models for satellite data harvesting, which contradicts the idea of a flat earth
SQUID are magnetometers
They measure magnetic fields very very very precisely
(Satellites also don’t work without gravitational forces. . .)
It even says it in these papers
They're comparing computational models for different data sets for easy of computation, or computability
Is the model outdated now? anything before 1995 shouldn't be cited in Zoology unless it's a huge deal
Absolutely, we have far better computing power in a wrist watch than a 1985 supercomputer
That's an exaggeration
But still
We have significantly better tools
Up until the mid 90's a lot of controllers were still analogue in areospace and even transport
Digital computers have made leaps and bounds being able to record gigabytes of data on a whim
So this FE proof is comparing the processing speed of how fast computers from 1985 can deal with satalitie data?
Compare that to 64kB of RAM
😏
Not specifically that no
I have 32 Gb in my personal computer
It's just that instrumentation has got a lot better so we don't really have to simplify the controllers too much
I wonder how many spaceships I could run
Sometimes, the error on additional corrections isnt needed at low altitude because your percentage error is too low
However
PID controllers have an accumulated error and need correcting
What if you only fire a rocket for 20 minutes?
What would that cumulative error mean?
Does your maneuver need to be that specific?
Absolutely not
That's why we don't simulate things in absolute detail
We even used sextants and classical mechanics on the way to the moon
Okay so, we simplify physics in some cases because we don't need to calculate everything?
You could calculate the spacetime curvature in GR
But you don't need to
Yeah
It's kinda laziness then?
That's the jist of it
Well, think of it this way
Diminishing returns on investment
You could correct all the problems but if they're not really problems because you don't need the precision why bother?
Okay that makes sense
"One is an analytical approach using a flat-Earth approximation to predict geopotential information quality as a function of spatial wavelength."
