The GPS network consists of 24 satellites, each of which makes two orbits around the earth per day. Each satellite transmits a 50.0- W (or even less) sinusoidal electromagnetic signal at two frequencies, one of which is 1575.42 MHz Assume that a satellite transmits half of its power at each frequency and that the waves travel uniformly in a downward hemisphereA)What average intensity does a GPS receiver on the ground, directly below the satellite, receive? (Hint: First use Newton's laws to find the altitude of the satellite.)I in W/m^2B)What is the amplitude of the electric field at the GPS receiver in part (a)?Emax in N/CC)What is the amplitude of the magnetic field at the GPS receiver in part (a)?Bmax in TD)How long does it take the signal to reach the receiver?TIME in s
