What is purpose of the principle of the doppler effect in the gps communication technology?

 

[eyeseeyou]

Just search it up

 

[Silky_Smooth]

Thought you chose the internet lol

But yeah just research it yourself, it's honestly not that hard

 

[Drsoccerball]

It can be used to calculate speed of travel

 

[Green Yoda]

It is used to measure the relative velocity of travel (magnitude and direction).

There are many satellites that orbit the Earth for GPS. AT least three of these can pinpoint exact locations. Each satellite can detect how far a location is from it, but not where it is. By using many satellites in conjunction, where each of the satellites distances intersect, it can be determined where the location is. All satellites use radio waves to do this. Where each of these distances intersect, from the satellites, is where the location is. This is called triangulations. The distance from each satellite can be determined because the speed of light is known, so speed x time = distance. Research in this area is occurring in new technologies called Global Navigation Satellite Systems (GNSS) which are more accurate and have an extended range, useful for mining and agricultural uses where signals may be blocked.

THAT'S ALL YOU NEED TO KNOW BASICALLY.

does it use trilateration or triangulation?
each website says something different

GPS uses trilateration. You can read about the mathematics of it here: https://en.wikipedia.org/wiki/Trilateration

If you're curious about the mathematics of triangulation (it's much simpler), you can read about it here: https://en.wikipedia.org/wiki/Triangulation#Distance_to_a_point_by_measuring_two_fixed_angles .

A combination of trilateration and triangulation is triangulateration, used in surveying: https://en.wiktionary.org/wiki/triangulateration .

okay i think ive got it

you did/doing adv science and then post grad medicine
am i rite
