Question

How can we find our position anywhere in the world

Answer 1

Answer:

The Global Positioning System lets us know where we are (and where we are going) anywhere on Earth. The GPS Block IIR(M) Satellite shown here is one of the various generations of GPS satellites orbiting the Earth. GPS satellites fly in medium Earth orbit at an altitude of approximately 12,550 miles .

Answer 2

Answer:

The GPS receiver gets a signal from each GPS satellite. The satellites transmit the exact time the signals are sent. So given the travel time of the GPS signals from three satellites and their exact position in the sky, the GPS receiver can determine your position in three dimensions - east, north and altitude
