PARIS — Satellite fleet operator Spacecom said the backup star tracker on its Amos-3 satellite had been taken out of service following an anomaly, but that the other tracker was functioning normally and satellite operations were not affected.
Amos-3, built by Israel Aerospace Industries (IAI), was launched in 2008 and is expected to operate until around 2027 owing to its being launched directly into geostationary orbit.
Operating from 4 degrees West, Amos-3 is Spacecom’s biggest revenue generator and as of June 30 accounted for some $209 million in backlog.
Spacecom said it was working with IAI on a solution.
Amos-3 needs only one tracker to function. Most satellites carry a backup in case of in-orbit issues.
An industry official unaffiliated with Spacecom said a problem with one tracker did not necessarily mean the other was at risk, and that the industry has known cases where a tracker is taken off line for several months but then returned to service.
