Lanteris 1300

The Lanteris 1300, earlier called the SSL 1300, LS-1300 and FS-1300, is a satellite bus produced by Lanteris Space Systems, formerly Space Systems/Loral. It is a modular platform with total broadcast power from 5 to 25 kilowatts and room for 12 to 150 transponders. First available in the late 1980s, it was revised several times over its design life. The earliest models gave 5,000 watts of radio frequency power, weighed 5,500 kilograms and needed a 4-metre launch fairing, while newer ones give about 10,000 watts, weigh 6,700 kilograms and need a 5-metre fairing. Among its firsts were a 100-volt bus for direct-to-home television, a true high-throughput satellite, the 20-kilowatt power level and two-way ground-based beam forming. In September 2015 the company announced that it had delivered 100 satellites based on the platform.
