Astranis

Builds small satellites for dedicated internet service

Astranis builds and operates small satellites that supply internet capacity to telecommunications companies, large enterprises, and government customers. Its MicroGEO spacecraft work in geostationary orbit, staying above the same region so customers receive continuous coverage without a large moving constellation. The company designs and manufactures satellites in-house, runs their ground networks, and earns revenue by leasing capacity or managing complete connectivity services. Its infrastructure supports cellular backhaul, aircraft connectivity, and broadband links in remote areas where ground networks are difficult to build. Astranis was founded in 2015 and is headquartered in San Francisco, California.
