The equation governing the satellite speed, derived from the Newton Kepler's Law is given by:
v^2 =( GM/R)^(1/2) , where, G is the gravitational constant and M is the mass of the planet and R is the distance of the orbitting satellite from the planet, irrespective of its mass.
Therefore, the different satellites with different masses but with same distance from the planet has the same velocity and period also. (This could also be confirmed by the 3rd law of Kepler, which does not involve the mass of the satellite.)
