SSL (company)

SSL, formerly Space Systems/Loral, LLC (SS/L), of Palo Alto, California, is a wholly owned manufacturing subsidiary of Maxar Technologies.

＜カリフォルニア州パロアルトの以前の宇宙システム/LORAL、LLC（SS/L）のSSLは、Maxar Technologiesの完全所有の製造子会社です。＞

SSL designs and builds satellites and space systems for a wide variety of government and commercial customers. 

Its products include high-powered direct-to-home broadcast satellites, commercial weather satellites, digital audio radio satellites, Earth observation satellites and spot-beam satellites for data networking applications.

History

The company was founded as the Western Development Laboratories (WDL) of Philco (Philco-Ford since 1966). 

The Space Systems Division was made a stand-alone Division of Aeronutronic/Ford Aerospace/ and was acquired by Loral Corp. in 1990 for $715 million from Ford Motor Company, and renamed Space Systems/Loral. 

All other divisions of Ford Aerospace including Western Development Labs now located in San Jose were also acquired by Loral at that time.

In 2012 Space Systems/Loral was acquired by the Canadian aerospace company MacDonald Dettwiler (now MDA) for $875 million. 

MDA was renamed as Maxar Technologies in 2017.

MDAは2017年にMaxar Technologiesに改名されました。

SSL's major competitors are Boeing Satellite Systems, Lockheed Martin, Thales Alenia Space, Airbus Defence and Space and JSC Information Satellite Systems.[1][citation needed]

Projects

In 1960, the Courier 1B, built by then Philco, became the world's first active repeater satellite.

SSL has recently pioneered research in electric propulsion systems, lithium-ion power systems and the use of advanced composites on commercial satellites, which permit significant increases in the size and power of a satellite's payload and extends the satellite's on-orbit lifetime.

 SSL also has developed new service-enhancing technologies such as super power systems for direct-to-user applications and ground-based beam forming, a technology that uses both satellite and terrestrial assets to provide mobile users with increased coverage and capacity capabilities.

As of December 2016, there are 87 SSL-built geosynchronous satellites in orbit.[2]
