About
Astranis Omega is the company’s second-generation MicroGEO satellite platform, unveiled in April 2024 as a significant performance leap over the original Prime satellite. Omega delivers over 50 Gbps of total throughput, representing roughly a four-to-five times improvement over the first-generation MicroGEO, while maintaining the small-satellite philosophy that makes Astranis competitive on cost. It achieves this through a much larger deployable antenna reflector that concentrates signal power and a larger solar array driving more capable solid-state power amplifiers.
Omega has a wet mass of 650 kg and stows to dimensions of 2m × 2.1m × 1.2m for launch. It transmits in Ka-band for civilian customers and additionally supports Military Ka-band and X-band for government and defense users. The software-defined radio payload supports advanced military waveforms including the U.S. Department of Defense’s Protected Tactical Waveform (PTW), and Astranis has secured a contract from Space Systems Command to integrate military communication capabilities into Omega satellites.
The all-electric propulsion system enables station-keeping and multi-mission relocation over the satellite’s 10-year operational lifespan. Customer launches are planned starting 2026, with a prototype satellite targeting 2025. Astranis plans to scale production to 24 Omega satellites annually. Approximately 70% of satellite components are manufactured in-house.
