You ask a question ... How GPS works?
Then post a pile of stuff including images which has nothing to do with the question.The GPS system doesn't give a rats about power or intensity I can't remotely understand those images so PLEASE TYPE IN WORDS.
I can triangulate a signal source with the strongest signal or the weakest it has no bearing I just need a timing advance in the signal. What makes a GPS work is the signal is special it includes a time stamp within the signal.
Read ... GPS uses 5 easy steps.http://www.trimble.com/gps_tutorial/howgps.aspx
In step 3 they say this "GPS needs very accurate timing which it achieves with some tricks". The trick is the put the timestamp in the signal.
I have no way to relate how a GPS works to your images. You either have no idea how a GPS works or you can't draw pictures.
So which is it you don't understand how a GPS works or you can draw?
SIMPLE EXAMPLE !
Sensor 1 has got huge SENSITIVE ! ( one foton )
Sensor 2 has got VERY VERY Low SENSITIVE ( 1 MJ )
WHAT IS BEETER sensor 1 or sensor 2 ?
HOW MANY JOULS/mm^2 is registering left/right wall ?
1861 J. C. Maxwell, published his theory of electromagnetic fields and radiation, which shows that light has momentum and thus can exert pressure on objects.
1901 P. N. Lebedev EXPERIMENTAL EXAMINATION OF LIGHT PRESSURE
Light or Radio 3D signal it is EM radiation
THE SIGNAL STARTED IN t=0
How big intensity is registering walls ?
HOW BIG FORCE IS PUSHING EARTH ?
CONSTANT ? or NOT ?
ORAC use Your brain ? please not read stupid theories about space !
MORE SIMPLE EVIDENCE to SEE black HOLE people are building more biger and more sensitive sensors !!!
me ..................LIGHT >>>..........black hole
light is not able hit black hole
me .............Light>>>......ball > 2m/s
I see ball because light hit ball and back to me
( I WILL NEVER SEE FRESH BALL POSITION !!!
me ........................BULB >>> XX m/s
if I have knowledge about bulb's power
bulb's size I can evaluate bulb's motion
I will never see "FRESH Position" for bulb
BUT i can evaluate where the BULB started 3D signal ?
ALSO bulb COLOUR is IMPORTANT !!!
