As people use google map(or other map) in their every day life, so this map view can help them to understand the location of the satellite easily.

This view is the most amazing among other views, using first person view, users will be able to see how the earth looks from satellites in real-time (present/past/future) considering the position and altitude of the satellites and the day-night condition of earth. And somewhere it gives the user an experience of sight seeing and space travelling.
