Stephen Kuper

Lockheed Martin’s third satellite based on the modernised LM 2100 bus launched from the Guiana Space Centre in French Guiana aboard an Ariane 5 rocket and is travelling to its transfer orbit for a series of in-orbit tests before operations are handed over to Sky Perfect JSAT Corporation.

JCSAT-17 will provide flexible mobile communications services to users in Japan and the surrounding region.

JCSAT-17 is the first mobile satellite service (MSS) communications satellite built on the modernised LM 2100, which includes 26 innovations that make the satellite more powerful, flexible and versatile in orbit.

A reprogrammable mission processor adds flexibility as mission needs change. Lockheed Martin is currently manufacturing five modernised LM 2100-based satellites for commercial and government customers.

Guy Beutelschies, Lockheed Martin vice president for communication satellite solutions, said, "Advanced mobile satellite communications are necessary as the world consumes more and more data in the transition to 5G."

The satellite's payload incorporates S-band and C-band transponders with a flexible processor along with 18-metre mesh reflector, enabling assured communications continuity during high-volume events.

The satellite also features robust Ku-band connectivity. JCSAT-17 is the eighth satellite built by Lockheed Martin for SJC, beginning with NSAT-110, JCSAT-9 through JCSAT-13 and JCSAT-110R.

"This satellite will diversify and harden Japan's communications infrastructure, by adding new options for mobility, bandwidth where it's needed, and reliable connections," Beutelschies added. 

Headquartered in Bethesda, Maryland, Lockheed Martin is a global security and aerospace company that employs approximately 105,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services.
