First, we have to find the speed of the satellite,
V = (G me / R )1/2
Here,
R = Radius of earth + altitude distance
= 6.37 x 107 + 3 x 107
= 9.37 x 107 m
G = gravitational constant = 6.67 x10-11 Nm2/kg2
me = mass of earth = 5.97 x 1024 kg
V = (G me / R )1/2
= ( 6.67 x10-11 x 5.97 x 1024 / 9.37 x 107 )1/2
= (39.8199 x 1013/ 9.37 x 107)1/2
= (4.2497 x106)1/2
V = 2.0614 x 103 m/s
V = 2πr/ T
T = 2πr/ V
= 2 x 3.14 x 9.37 x 107 / 2.0614 x 103
= 58.8436 x 107/ 2.0614 x 103
T = 28.54 x 104 second
1 hour = 3600 second
T = 28.54 x 104/3600
= 0.7929 x 102
T = 79.29 hour

Global positioning satellites (GPS) can be used to determine positions with great accuracy. The system works by determining the distance between the observer and each of several satellites orbiting Earth. If one of the satellites is at a distance of 20,000 km from you, what percent accuracy in the distance is required if we desire a 2-meter uncertainty? Express your answer using one significant figure. How many significant figures are needed in the distance? Express your answer as an integer.
Part C please The GPS (Global Positioning System) satellites are approximately 5.18 m across and transmit two low-power signals, one of which is at 1575.42 MHz (in the UHF band) in a series of laboratory tests on the satellite, you put 1575.42 MHz UHF transmitters at opposite ends of the satellites. These broadcast in phase uniformly in all directions. You measure the intensity at on a circle that is hundred meters in radius and centered on the satellite. You measure...

The navstar global positioning system uses a group of 24 satellites in orbit around the earth. By triangulation and the signals transmitted by these satellites the position of a receiver on the ground can be determined with a precision of a few centimeters. The orbits of the satellites are evenly distributed around the earth, with four satellites in each of six orbits allowing fixed positions of continuous navigation. the satellites orbit at an approximate altitude of 11,000 nautical miles a)...
