The thesis

What if satellites could fly 3× closer to Earth?

A closer orbit means sharper data, faster links, stronger signal, and orbits that clean themselves. The case for VLEO is the case for physics.

Physics, not marketing

Why closer is better.

Every advantage of VLEO falls out of one fact: you are nearer to what you are observing and talking to. Distance is the tax that traditional LEO pays.

Sharper resolution
Aperture scales with altitude. Same optics, three times the detail.
Lower latency
Shorter slant range, faster round-trip.
Stronger signal
Inverse-square law working in your favour.
Lower
Radiation
Below the inner Van Allen belt — less shielding, cheaper electronics.

baseline

Illustrative — physics-based approximations referenced to a 600 km baseline.

Slide between 200 km and 800 km and every metric responds at once — resolution, latency, signal, radiation, de-orbit time. Nothing here is marketing; it is the geometry and physics of a lower orbit.

The closer you get, the better the mission — until drag becomes the problem nobody could solve. That is the catch.

The catch

VLEO was dismissed as too hard.

The same atmosphere that cleans the orbit also pulls satellites down. Conventional propulsion runs out of fuel in months — GOCE and Tsubame both ran dry. For decades that ended the conversation.

The push

And LEO keeps getting worse.

VLEO isn't only better — the orbit above it is deteriorating. Debris growth, escalating collision-avoidance manoeuvres, and the Kessler trajectory all push operators to look lower.

Why now

The window is open.

Regulation

The FCC 5-year deorbit rule and ESA Zero Debris Charter reward orbits that clear themselves.

Demand

Direct-to-device, sub-meter imagery, and sovereign capability are all spiking at once.

First-mover

The propulsion barrier just fell. The operators who move first define the band.
