Astranis is building small, low-cost telecommunications satellites to connect the four billion people who currently do not have access to the internet. Each spacecraft operates from geostationary orbit (GEO) with a next-generation design of only 350 kg, utilizing a proprietary software-defined radio payload. This unique digital payload technology allows frequency and coverage flexibility, as well as maximum use of valuable spectrum. By owning and operating its satellites and offering them to customers as a turnkey solution, Astranis is able to provide bandwidth-as-a-service and unlock previously unreachable markets. This allows Astranis to launch small, dedicated satellites for small and medium-sized countries, Fortune 500 companies, existing satellite operators, and other customers.

Astranis launched a first test satellite into orbit in 2018 and is now underway with its first commercial program-a satellite to provide broadband internet for Alaska that will more than triple the available bandwidth across the state. The satellite is undergoing assembly, integration, and test and is set for a launch later this year.
