As the satellite around the earth moves in a circular direction.
Therefore at every point in its path it will be tangential or perpendicular to the center of the earth.
Thus the work done = F *s * cos theta
But the theta is 90 since the satellite is tangential to the circle.
thus work done= F * s * cos 90 = 0
since cos 90 = 0
