Understand the mission

Why satellites use different orbits

Connect an orbit’s altitude, inclination and shape to the job a satellite is designed to do.

Start with the job

An orbit determines what a satellite can see and how its view changes. Lower orbits bring a spacecraft closer to Earth; higher orbits provide a wider view. There is no single best orbit for every mission.

A changing view or a steady one

A geostationary satellite remains above the same point on the equator. Sun-synchronous orbits support observations under similar lighting conditions. These choices suit different kinds of communications and Earth observation.

The first orbit may not be the destination

A transfer orbit is an intermediate path. The spacecraft may need further propulsion to reach its operational orbit. A launch record describing a transfer should not be read as the final service location.

Explore an example

Use Spacian’s orbit guide to compare LEO, MEO, GEO, sun-synchronous and transfer examples. The models are accelerated illustrations, not live spacecraft positions. Then open a mission and compare its published destination orbit.
