As an example, for a=7200 km (the spacecraft about 800 km over the Earth surface) one gets with this formula a sun-synchronous inclination of 98.696 deg. Note that according to this approximation cos i equals −1 when the semi-major axis equals 12 352 km, which means that only smaller orbits can be sun-synchronous. The period can be in the range ...

A walking orbit whose orbital plan precesses with the same period as the planet's solar orbital period. In such an orbit, a satellite crosses periapsis at about the same local time every orbit.

A sun-synchronous orbit. Image credit: Galactics A special case of a near-polar orbit in which a satellite, in going around the Earth, passes over the same points on the Earth's surface at the same local times each day and a different swathe of territory on each orbit. This kind of orbit involv...

A spacecraft orbit that precesses, wherein the location of periapsis changes with respect to the planet's surface so as to keep the periapsis location near the same local time on the planet each orbit. See walking orbit.
