<p><b>New page</b></p><div>A satellite in synchronous orbit takes one day to complete one orbit, making the satellite return to the same point above the ground every day. If a satellite's inclination is 0 and the orbit is perfectly circular, it will appear stationary in the sky. If the inclination is nonzero and the orbit is non-circular, then the satellite will follow the path of a figure 8 about a central point on the equator.<br />
<br />
For a satellite to maintain a synchronous orbit around Mars, set the orbital period of a satellite equal to one sidereal day.<br />
<br />
T = 2 pi sqrt(a^3 / mu)<br />
<br />
where:<br />
<br />
* T = the orbital period, which is set to one sidereal day on Mars, 88642.66 s<br />
* mu = GM = the standard gravitational parameter, which is 4.282837e4 km3 s−2 for Mars<br />
* a is the semi-major axis of the orbit<br />
<br />
Solving for a, we get<br />
<br />
a = 20,427.7 km<br />
<br />
For an [[Areostationary orbit]], the radius will be 20,427.7 km and the inclination will be zero.</div>Pb
