Astranis Space Technologies was founded in 2015 and has its headquarters in San Francisco, California, United States. It aims to build compact, cost-efficient geostationary communication satellites (MicroGEO) to deliver affordable and dedicated broadband services. Their technology emphasizes rapid turnaround, digital flexibility via software-defined radios and mission resiliency. Their satellites contain onboard propulsion systems enabling relocation and flexibility, particularly with the multi-mission, UtilitySat, which can reposition to serve different customers over time.
Astranis partnered with SpaceX for multiple dedicated Falcon 9 launch contracts for deploying blocks of MicroGEO satellites. Astranis’s first commercial MicroGEO satellite, Arcturus was intended to expand broadband capacity in Alaska. It partnered with Thaicom to provide the Thaicom-9 satellite over Asia. Astranis signed a strategic agreement with Chunghwa Telecom for Taiwan’s first dedicated MicroGEO satellite.
Astranis satellites feature proprietary Software-Defined Radio (SDR) systems that enable dynamic reconfiguration of frequencies and bandwidth from orbit. This allows retuning around interference, adjusting coverage on the fly, and even updating flight software remotely. Their SDR operates across 7 GHz of simultaneous bandwidth. The UtilitySat introduces a world-first dual-propulsion architecture combining chemical monopropellant thrusters with electric ion propulsion. This enables rapid repositioning along the GEO belt while also offering precision station-keeping. Astranis' MicroGEO satellites are significantly smaller and lighter than traditional GEO platforms. They are designed to be radiation-hardened and withstand solar storms.
Key products
MicroGEO Communications Satellites
The MicroGEO is Astranis Space Technologies’ flagship line of small, high-performance geostationary communications satellites. Unlike traditional GEO spacecraft that are massive, expensive, and slow to build, MicroGEO satellites are compact, cost-efficient, and deployable on rapid timelines, delivering the same core service of reliable and wide-area broadband coverage. At the core of MicroGEO is a software-defined radio (SDR) payload, enabling operators to dynamically reconfigure frequencies, bandwidth, and coverage areas from orbit. This flexibility allows the satellites to adapt to shifting customer demand, mitigate interference, and extend service lifespans without hardware redesigns.
Each MicroGEO is equipped with a radiation-hardened design for GEO environments, robust onboard propulsion for station-keeping, and high-throughput capabilities that can scale into tens of gigabits per second. The platform is engineered for regional operators, ISPs, and enterprise customers who need dedicated GEO capacity without waiting years or investing in billion-dollar infrastructure. Astranis provides MicroGEO satellites both as capacity services (leasing bandwidth directly) and as turnkey assets for telecom providers. The model supports rapid scaling of connectivity in underserved regions, bridging the digital divide with designed, localized broadband solutions.
UtilitySat
UtilitySat is designed to bring unprecedented agility to geostationary communications. Unlike conventional satellites locked to a single orbital slot and mission profile, UtilitySat is equipped with a dual-propulsion system, combining chemical thrusters for rapid relocation and electric propulsion for efficient long-term station-keeping. This unique architecture enables the satellite to reposition multiple times over its lifetime, serving different customers and regions as connectivity demands evolve. It features Astranis’ software-defined radio (SDR) payload, allowing operators to dynamically reprogram frequencies, bandwidth, and beam coverage. The first UtilitySat was launched on a dedicated SpaceX Falcon 9 mission in December 2024, alongside other Astranis MicroGEO satellites, and has already begun demonstrating its versatility. It represents a new category of satellite capability, giving operators and enterprises a way to adapt to today’s fast-changing connectivity needs without the delays and costs of traditional GEO infrastructure.
Omega
Omega is the most advanced evolution of Astranis Space Technologies’ MicroGEO platform, engineered to deliver massive throughput at lower cost and faster deployment cycles than traditional geostationary satellites. While Astranis’s first-generation MicroGEO satellites provided dedicated regional broadband with compact, affordable designs, Omega scales this vision into a high-capacity powerhouse capable of more than 50 Gbps per satellite. At the core of Omega is Astranis’s proprietary software-defined radio (SDR) system, upgraded to handle significantly greater bandwidth, more dynamic beamforming and highly flexible frequency management across Ka and Ku-bands. This digital payload allows real-time adjustments to coverage, ensuring operators can maximize spectral efficiency and designed services for changing market demand. Omega satellites also feature enhanced power systems, expanded payload capacity, and advanced thermal management, making them suitable for both commercial broadband delivery and high-priority government or defense communications.
Nexus
Nexus is Astranis Space Technologies’ specialized satellite platform designed to support resilient navigation and timing services in geostationary orbit. Unlike traditional GEO communications satellites, Nexus is optimized for Positioning, Navigation, and Timing (PNT) missions, providing a secure, high-availability backup to the U.S. Global Positioning System (GPS). Developed under contract with the U.S. Space Force, Nexus is part of the Resilient GPS (R-GPS) program, which seeks to augment and safeguard national navigation infrastructure against threats such as jamming, spoofing, and signal degradation. Nexus satellites are equipped with Astranis’s proprietary software-defined radio (SDR) technology, enabling them to generate and broadcast GPS-compatible signals that can be rapidly updated, hardened and reconfigured from orbit.
Astranis Space Technologies is reshaping the economics and flexibility of geostationary satellites by proving that smaller, smarter and more agile spacecraft can deliver world-class performance at a fraction of the cost. With its expanding product family of MicroGEO for dedicated regional broadband, UtilitySat for multi-mission roaming, Omega for high-capacity next-gen connectivity, and Nexus for resilient navigation and security, Astranis is positioning itself as a key enabler of global communications and national infrastructure.
