Phased array antennas from Austin, Texas-based CesiumAstro will enable SBN-1 to provide high-throughput services at more than 120 gigabits per second.
Saturn Satellite Networks selected CesiumAstro’s Vireo-GEO active phased array RF payload for the Space BroadbandNetworks-1 (SBN-1) program.
Vireo-GEO is a CesiumAstro payload that provides direct radiating array technology reconfigured and optimized for GEO operation.
The SBN-1 payloads will be developed at CesiumAstro’s facilities in Austin, Texas for integration into Saturn Satellite Networks’ Intelligent Space Node (ISN) low-cost GEO platform at a partner’s Silicon Valley facilities.
CesiumAstro's active phased array communications payloads are designed for turnkey, stand-alone operation with integrated waveforms, requiring only ethernet and power.
DIFI Chairman Stuart Daughtridge stated that CesiumAstro will help further the maturity and adoption of the interoperable digital IF standard.
Increased support for digital IF in the industry will allow CesiumAstro payloads to be compatible with a wider range of backend modems.
The increased operability from DIFI will improve the breadth of applications and reduce time to market for customers of CesiumAstro.
CesiumAstro, Inc. joined the Digital Intermediate Frequency Interoperability (DIFI) Consortium on June 21, 2022.
CesiumAstro’s phased array payload architecture is software-defined with a digital backend, making them DIFI-ready by design.
CesiumAstro secured $60,000,000 in an oversubscribed Series B funding round co-led by Airbus Ventures and Forever Ventures with strategic participation from L3Harris Technologies.
CesiumAstro has raised nearly $90,000,000 in capital since its founding in 2017.
CesiumAstro is set to deploy several additional assets into space later 2022 with targeted launch dates to be announced.

Cesium, O3DE, The Linux Foundation, and AWS provide tutorials in a Learning Center and host the Cesium for O3DE project on GitHub.
CesiumAstro supplies the CommPack with all necessary intra-system harnessing so the system requires only DC power connection and digital data from the spacecraft.
CesiumAstro powers the CommPack with its SDR-1001 software-defined radio and supplies two active S-band antennas (AA-1S2T1) with each communications payload.
CesiumAstro released the S-Band CommPack Inter-Satellite Link built to NASA GEVS standards and made it available in volume on 2022-01-11.
