Status: Operational 1985. First Launch: 1985-03-22. Last Launch: 1989-01-27. Number: 6 . Gross mass: 2,013 kg (4,437 lb). Height: 2.80 m (9.10 ft). Span: 15.90 m (52.10 ft).
Modifications included a larger communications payload with internal weight savings to accommodate the additional mass. The payload included 26 C-Band and 6 Ku-Band transponders, providing 15,000 voice circuits and two television channels.
The 5A series (F1-F6) was also known as Intelsat 5 (F10-F15). The spacecraft was 3-axis stabilized to 0.4 deg with momentum wheels and used a hydrazine propulsion system and passive thermal control. Dual solar arrays provided 1800 W (BOL) and charged nickel hydrogen batteries.
