SSL 1300

The SSL 1300, previously the LS-1300 and the FS-1300, is a satellite bus produced by SSL (company). Total broadcast power ranges from 5 to 25 kW, and the platform can accommodate from 12 to 150 transponders. The SSL 1300 is a modular platform and SSL no longer reports designators for sub-versions, such as: 1300E, 1300HL, 1300S, 1300X.

First available in the late 1980s, the SSL 1300 platform underwent revision multiple times over its design life, all the while remaining a popular communications platform. The earliest models provided 5,000 RF watts of transmitter power, weighed 5,500 kg, and required a 4-meter diameter launch fairing. Newer models provide double that, approximately 10,000 RF watts of transmitter power, weigh 6,700 kg, and require a 5-meter diameter launch fairing.

In September 2015 SSL announced that it had delivered 100 satellites based on the SSL 1300 platform. There are more SSL 1300's currently providing service on orbit than any other model communications satellite.
