The space segment currently consists of 28 operational satellites orbiting the earth. They orbit at a height of almost 21,000 km above the earth's surface. Any one satellite completes its orbit in around 12 hours. Due to the rotation of the Earth, a satellite will be at its initial starting position after approximately 24 hours.
