Hi Nikki,
Global positioning system is a method of identifying location or position of any detail on earth using a system of 24 satellites, which are continuously orbiting, observing, monitoring and mapping the surface of the Earth. Each satellite revolves around earth twice a day at a distance of about 20000 km.
The entire new topic added in the chapter can be considered important because it is being introduced for the first time.
