Global Positioning System  is the method of showing Earth's surface relies on a network of orbital satellites.

C

Explanation:

Global Positioning systems are a group of satellites which circles above the earth surface to cover and store the information related to positioning of objects on earth’s surface.

The basic principle used by GPS are that the distance between the object on the earth surface and the satellites in three different positions are measured and that distance is confirmed by a satellite in fourth direction.

This helps to provide more accurate Earth’s surface images. So as the satellites in GPS orbits round the earth in its specific orbit ,they are also termed as orbital satellites.

So the group of orbital satellites forming a network used in global positioning system shows the earth’s surface accurately and precisely.
