Taiwan Space Agency Awards Contract to CesiumAstro
Company will Deliver Space Payloads and Ground Systems for Communications Constellation
The Taiwan Space Agency has awarded a contract with CesiumAstro to deliver software-defined radio (SDR) space communications payloads and ground user terminals for Taiwan’s first low-Earth orbit (LEO) communications satellite constellation.
“Our modular, flight-proven payload technologies align with TASA’s goals for performance, flexibility, and future scalability."

This contract marks a major milestone in Taiwan’s effort to build sovereign LEO communications infrastructure and accelerate the deployment of its indigenous satellite communications network. The Beyond 5G LEO Satellite (B5G) program will receive both space- and ground-based active phased array systems from CesiumAstro, including its Vireo Ka space payload and Skylark user terminal.
“We are honored to support TASA’s vision for next-generation communications,” said Shey Sabripour, Founder and CEO of CesiumAstro. “Our modular, flight-proven payload technologies align with TASA’s goals for performance, flexibility, and future scalability, and we look forward to delivering systems that support their ambitions for 5G and beyond.”
The B5G satellites are a critical step in establishing Taiwan’s capacity to design, manufacture, and operate LEO communications satellites. CesiumAstro’s contributions will include a complete space payload leveraging its Vireo Ka active phased array technology, with support for multiple independently steerable beams, real-time reconfigurability, and high-throughput performance.
Complementing the space segment, CesiumAstro will also deliver Skylark ground terminals, designed to support resilient user-side connectivity across a range of mission profiles.
“As Taiwan invests in secure, sovereign communications infrastructure, CesiumAstro is proud to contribute best-in-class technology and a commitment to mission success,” said Trey Pappas, Chief Revenue Officer at CesiumAstro. “This contract reflects the growing international demand for proven, reconfigurable space communications systems.”
The B5G program is led by the Taiwan Space Agency and forms part of Taiwan’s National Space Technology Long-Term Development Plan which prioritizes domestic resilience and global competitiveness in emerging technologies, including space-based communications.
