SSL 1300
The 1300 series platform is an orbital satellite platform produced by Space Systems/Loral. Total broadcast power ranges from 5 to 25 kW, and the platform can accommodate from 12 to 150 transponders.[2]
First available in the late 1980s, the FS-1300 platform underwent revision multiple times over its design life, all the while remaining a popular communications platform.[3] 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.[4]
