Next Generation GEO Platform Targets Lower Cost, Greater Access for Government and Commercial Markets

Sidus Space (NASDAQ: SIDU) (the “Company” or “Sidus”), an innovative, agile space mission enabler, today announced the signing of a Memorandum of Understanding (MOU) with Saturn Satellite Networks, Inc., a pioneering developer of space-based reprogrammable payloads and geostationary (GEO) satellite solutions redefining access to space communications. This agreement outlines a strategic collaboration to support the development and deployment of Saturn’s SBN-X platform — a new low-cost, high-performance GEO satellite solution. Under the MOU, Sidus Space will work closely with Saturn to provide critical support across various activities. Saturn intends to award Sidus a scope of work that includes Assembly, Integration, and Testing at Sidus’ advanced manufacturing facilities in Cape Canaveral, Florida; acquisition of certain satellite subcomponents; as well as mechanical component engineering and manufacturing services.

“We are excited to collaborate with Saturn Satellite Networks on the groundbreaking SBN-X initiative,” said Carol Craig, CEO of Sidus Space. “The selection of Sidus as Saturn's partner leverages our proven expertise in spacecraft design, integration, and testing, while aligning with our mission to provide flexible, cost-effective space solutions for commercial and government customers.”

The SBN-X platform is designed to provide affordable GEO satellite communications offering a 5kW analogue payload and 100Gbps high-throughput, digital payload system. The collaboration between Sidus and Saturn is expected to broaden market access and expand both companies’ capabilities in supporting new and emerging GEO communications needs.

“Our partnership with Sidus Space strengthens the foundation of the SBN-X platform, combining their agile manufacturing capabilities with our vision for transforming GEO communications,” said Tom Choi, CEO of Saturn Satellite Networks. “Together, we’re positioned to rapidly deliver next-generation satellite solutions, at a significantly lower price point, to meet the rapidly evolving demands of expanding global markets.”

About Saturn Satellite Networks, Inc.

Established in 2017 and launched in 2018 Saturn Satellite Networks (SSN) Inc., is a space technology and service developer lead by an experienced team of satellite design, manufacturing, sales, and operations professionals with over 300 years of experience to redefine the approach for creating reliable and affordable satellites at GEO, MEO and LEO. The company initially developed the Nationsat a 2kW GTO platform in 2018 - 2019. Nationsat achieved and passed the PDR based on a contract with an international customer. Saturn then developed the SBN-1, a 10kW 100Gbps HTS satellite using an all-digital, reprogrammable payload provided by CesiumAstro. Given the changing market dynamics of the GEO markets and taking the lessons learned from the earlier programs, SSN has evolved its approach to GEO and NGSO by introducing their newest platforms called SBN-X and Caelsat in 2024 and 2025. The newest systems provide the best-in-class power, cost and a very innovative approach to the launch options ensuring compatibility with established launch systems along with newly emerging mini launchers. We work with world leading third party components into our system to ensure not only lower costs but maximum reliability and advanced technologies. We work with end users, government as well as satellite operators to provide technology and financing solutions to meet their requirements for affordable space. https://www.saturnsatellite.net/
