Phasing & deployment

Beginner ~10 min Slide deck Free

Every constellation launch injects a batch of satellites into nearly the same orbit. They don't arrive pre-spaced. Phasing maneuvers — tiny period differences — gradually walk each satellite to its designed slot.

What this lesson covers

How Phasing Actually Works

Phasing deliberately exploits Kepler's third law: period scales with altitude. Operators use this constantly to position and reposition satellites.

Why Deployment Takes Time

Even with perfectly planned phasing burns, filling a shell is slow and careful — not an instantaneous switch-on.

What It Looks Like in Tracking

During deployment, tracking signatures are uniquely recognizable.

Key facts

💡ISS visitors use phasing burns for days before docking — matching the station's phase angle precisely.
💡SpaceX Starlink Group 6-1 (53 sats) took approximately 3 months to fully disperse into operational slots.
Shells fill gradually via phasing — orbital mechanics, not magic.

When you see a train of satellites on Orbital Radar slowly spreading from a cluster, you're watching Kepler's third law used as a precision positioning tool.
