What JSAT International does

JSAT International Inc. is a U.S.-based satellite communications provider and wholly owned subsidiary of Japan's SKY Perfect JSAT Corporation, founded in 2001 and headquartered in Washington, D.C. The company operates the Horizons joint-venture satellite fleet with Intelsat — comprising Horizons-1 (150°W), Horizons-2 (74°W), Horizons 3e (169°E, HTS), and Horizons-4 (127°W) — and represents the U.S. commercial face of Asia's largest satellite operator group, giving customers access to 17 total satellite options spanning the Americas, Pacific, Asia-Pacific, and Antarctica.

The company's product portfolio centers on flexible transponder leasing (full-time and occasional usage) with engineering-driven network design and link-budget analysis, complemented by ground connectivity and earth-station services delivered through SKY Perfect JSAT-owned teleports (YSCC, SPE, SPW, GTC) and partner teleports including Hawaii Pacific Teleport and Intelsat-operated facilities. The technology stack is anchored in geostationary-orbit Ku-band and C-band capacity, including High Throughput Satellite (HTS) multi-spot-beam technology with multiport amplifiers and digital channelizers on Horizons 3e. In 2025 the company extended into Earth observation through JSAT Beyond Innovation LLC and into LEO/optical communications via the Planet Labs constellation partnership and Apolink/Space Compass optical data relay MOU.

Go-to-market is enterprise field sales — primarily quote-based, multi-year transponder leasing contracts — supplemented by teleport-channel partnerships globally. Customer segments span government and defense (Japan Ministry of Defense, NASA Artemis II), maritime and aeronautical mobility (NYK Cruises, SES in-flight Wi-Fi), mobile network operators requiring wireless backhaul, and events/disaster-response use cases (GLION ARENA KOBE). Pricing is not publicly disclosed and is tailored to satellite configuration and usage requirements, with a subscription/managed-services revenue model underpinning recurring revenue.
