For 60 years, satellite communication lived 35,786 km up, parked over the equator. Now a wave of constellations is dropping to a few hundred kilometres — and rewriting the economics of space. This is the GEO → LEO transition.
Four ways to circle a planet — tap any orbit to explore it. Illustrative, not to scale.
Geostationary satellites solved one problem brilliantly: park a spacecraft over a fixed spot and it can blanket a third of the planet from a single point. But distance is unforgiving. Signals crawl ~36,000 km up and back, adding heavy delay and demanding large, power-hungry dishes. Low Earth orbit flips the model — hundreds of small, cheap satellites flying close and fast, handing your connection off seamlessly as they streak across the sky.
Two live views, computed for your approximate location right now. Left: low Earth orbit satellites currently overhead. Right: geostationary beams lighting up your spot on the globe.

Two very different ways to put a radio in the sky.
The idea is decades old. The economics are brand new.
Reusable rockets cut the cost of reaching orbit by an order of magnitude, making thousand-satellite fleets affordable.
Flat-pack satellites built on assembly lines, not hand-crafted — launched by the hundred per rocket.
Video calls, cloud apps, gaming and trading need responsiveness GEO physically can't deliver.
Electronically steered flat panels track fast-moving satellites with no moving parts.
Rural, maritime, aviation and disaster zones where laying fibre is impossible.
Laser crosslinks let constellations route traffic in space, reducing dependence on ground stations.
A handful of operators are racing to fill low Earth orbit. Here's where the main constellations stand in 2026.
The runaway leader. SpaceX passed roughly 10,000 operational satellites in early 2026 and holds FCC clearance for up to 15,000. Its Direct-to-Cell service — 650+ dedicated satellites and growing — now offers texting almost anywhere through partners like T-Mobile, with full voice and data targeted for the Starship-launched V2 generation from 2027.
The only operator flying GEO and LEO together. After a €5.8B refinancing, Eutelsat ordered 440 next-generation OneWeb satellites from Airbus (deliveries from late 2026) and is anchoring the EU's sovereign IRIS² constellation, supported by a French government bridge contract worth up to €350M.
Rebranded from Project Kuiper in late 2025. Enterprise beta went live in April 2026 with partners including Verizon, AT&T, Vodafone, JetBlue and NASA, targeting commercial service by mid-2026. With ~210–240 of a required 1,618 satellites in orbit, Amazon is racing to double its launch cadence across SpaceX, ULA, Arianespace and Blue Origin.
Canada's enterprise- and government-focused network, built with MDA Space. Two Pathfinder satellites are slated for late 2026 ahead of a heavy 2027 launch cadence; full global commercial service is now expected around Q1 2028, once 96 of the planned 156 satellites are operational.
Shanghai-backed "Thousand Sails" (G60) — the most active Chinese constellation, aiming at 15,000+ satellites. Deployment passed 200 satellites in 2026 on regular Long March 6A/8 launches, and Spacesail is signing international distribution deals (Brazil, Kazakhstan and others) as a direct Starlink challenger.
China's state-owned answer to Starlink — a planned 13,000-satellite network run by China SatNet. Roughly 190 satellites were in orbit by mid-2026 with a year-end target near 310, ramping steeply toward 900 in 2027 and 3,600 per year from 2028 on Long March 5B/12/6A rockets.
Syncom 3 becomes the first geostationary satellite — the GEO era begins and defines satcom for half a century.
First-generation LEO ventures (Iridium, Globalstar) prove the concept for voice — but launch costs make broadband uneconomic.
The modern LEO broadband race begins as the first large commercial constellation starts launching at scale.
Thousands of LEO satellites on orbit; consumer terminals, maritime, aviation and enterprise adoption accelerate worldwide.
GEO and LEO increasingly work together — hybrid networks pairing GEO's broadcast reach with LEO's low-latency lanes.
The transition isn't a clean replacement. Each orbit keeps the jobs it does best.
One satellite covering a continent is unbeatable for broadcast TV, wide-area data distribution, and stable fixed links where latency doesn't matter. A handful of GEO birds can serve millions simultaneously with no handovers and decades of proven reliability.
Anything interactive — real-time communication, cloud workloads, IoT, defence and mobility — flows to LEO's short, snappy round-trips. The future most operators are betting on is multi-orbit: intelligent terminals that roam across LEO, MEO and GEO depending on what each moment needs.
GEO2LEO tracks the migration that's reshaping global connectivity — orbit by orbit, constellation by constellation.
