AscendArc

AscendArc is an American satellite communications startup building a next-generation geostationary satellite constellation for high-capacity broadband services. Based in Portland, Oregon, the company is developing advanced software-defined GEO satellites capable of flexible bandwidth allocation and dynamic beam forming.

The company's satellite platform leverages modern digital payload technology to deliver high-throughput connectivity to underserved markets. AscendArc's approach focuses on software-reconfigurable payloads that allow in-orbit repurposing of capacity to match shifting demand patterns, providing operators with greater flexibility than traditional fixed-beam GEO satellites.

AscendArc is targeting enterprise, maritime, aviation, and government connectivity markets where GEO satellites' broad coverage footprint and high power levels offer significant advantages. The company's constellation design emphasises frequency reuse and multi-beam coverage to maximise spectral efficiency.

With a team of experienced satellite industry veterans, AscendArc is advancing through the design and development phase, working toward the deployment of its first satellite.
