Problem
Traditional geostationary (GEO) communication satellites are large, expensive, and have long development cycles, limiting their use for many regional and commercial applications. Low‑Earth‑orbit (LEO) constellations require dozens or hundreds of satellites to provide continuous coverage, often over areas with insufficient demand, leading to inefficient resource use.
Solution
AscendArc builds small (< 1,000 kg) high‑throughput GEO satellites that are volume‑produced using manufacturing methods derived from LEO satellite production. By applying all‑electric propulsion and software‑defined, reconfigurable payloads, the satellites can be launched and deployed rapidly while maintaining a 10‑year design life. The approach reduces launch and operational costs and delivers a ten‑fold improvement in cost per megabit per second compared with legacy GEO platforms. The satellites are engineered to meet U.S. Department of Defense frequency, encryption, and anti‑jamming requirements, making them suitable for both commercial operators and secure government communications.
Target Audience
Primary customers are regional telecommunications operators seeking affordable high‑throughput GEO capacity (e.g., South Korea’s KT Sat) and government or defense agencies requiring secure, resilient satellite communications.
