What a ground track actually is

Beginner ~9 min Slide deck Free

The ground track is the path the satellite traces over Earth's surface. The orbital plane is fixed in inertial space. Earth rotates underneath it.

What this lesson covers

Why It Looks Like a Sweeping Sine Wave

The classic sinusoidal ground track shape emerges from two combined motions — fast orbital speed versus slow Earth rotation.

How Orbital Radar Shows This

When you use Orbital Radar, you're looking at both views simultaneously — and they answer different questions.

Key facts

💡The 'wobble' in the line is real orbital geometry, not a drawing convention.
A ground track is not where the satellite is — it's the orbit seen from a rotating Earth.

The orbit itself is simple. The ground track is the product of two independent motions — and it's the one that matters for coverage, revisit, and targeting.
