Italy's first operational communications satellite was launched 15 January 1991 by an Ariane-44L H10 booster. Developed by a contractor team led by Alenia Spazio, Italsat carries ten active transponders plus five spares for 30/20 GHz and 50/40 GHz links with a capacity of 12,000 telephone circuits.
ITALSAT 1 was lifted into orbit during the mission ‘Ariane 44L | Italsat 1’, on board a Ariane 44L space rocket.
The launch took place on Jan. 15, 1991, 11:10 p.m. from Ariane Launch Area 2.
