It's no slur if it's fact.
They still say companies like Space Imaging are a conspiracy. Even though you can see pictures they have taken and stuff. Then they just ignore over half the argument. Kinda like the GPS argument. It just died because they didnt have any comebacks.
That how does a balloon floating in the wind know where it is? Or a plane? They cant know where they are. Look it, the satellites are in know orbits, thus making it easy to tell where they are.

VOR, DME, and NDB's. Not to mention INS.
It's actually about 50 feet and upwards of 200 feet vertically.
yup. And like I said, that is way better then the instruments you use.
Read the FAQ and lurk more.
GPS uses satellites.
Time is never wasted when you're wasted all the time
tl;dr

Also, the receiver often times calculates a 'probable' area, due to sphere overlap. This will get you even less accuracy.
Well what usually happens is we get the same stupid straw-man argument "GPS does not require satellites". What this has to do with the fact that GPS does in fact use satellites is beyond me. I've compared it in the past to arguing against the existence of boats and planes by saying "Crossing the atlantic does not require boats and planes". I don't see many people swimming across the ocean though.
Nope, multiple satellites will allow the spheres to line up at one point. The error is 3 meters on my bros unit. Not more not less. New receivers take into account time dilation and all that good stuff.

You also have a clock error, a multipath error, calculation error, and atmospheric errors. Due to the uncertainty in the calculation, the receiver often won't have spheres that align at only one point, therefore, the unit must calculate a numerically probable location.
