Four billion people still have no internet access. Astranis is here to change that.

We are building the next generation of internet satellites.

The Problem

Internet satellites are as big as double-decker buses and cost hundreds of millions of dollars to build and launch.

As a result, it only makes economic sense to place legacy satellites over population centers.

Our Answer

Astranis improves access to internet connectivity by making smaller and more powerful satellites at a fraction of the cost.

This approach allows us to build our satellites in 12-18 months, about five times faster than our competitors.

MicroGEO: Our first production satellite

DESIGNED FOR geostationary orbit (GEO)

Operates for ten years in GEO, 35,786 km away from Earth


Re-programmable radio, even in orbit


At a wet mass of ~350 kg, far simpler and cheaper to launch

We will triple the satellite internet capacity of Alaska.

Thirty-nine percent of Alaskans don't have reliable access to internet— the highest rate of any U.S. state — and thousands live with no access at all. We're working to change that with an incredible partner, Pacific Dataport, Inc.
