Anik E2


Also called Telesat 10

General


Designation 21222 / 91026A
Launch date 5 Apr 1991
Country of origin Canada
Mission Telecommunications
Geostationary orbit see below
Launch vehicle Ariane V43

After Anik E1's incident, this satellite run out of control January 20th, 1994 at 21:00 local time after a magnetic storm. It distroyed the on-board stabilization system. To face this problem, Telesat has built a system that calculates and orders the satellite's movements from an Earth station.
This satellite was already victim of technical problems after launch to position its antennas.

On 30 Jul 1999 the satellite experienced another failure. Signals nearly disappeared at approx 20:00 UT and lasted a few hours. The reported cause was a severe magnetic storm.

In 2005, it secured the Venezuelan slot at 67°W before an actual Andesat satellite is launched. A chinese DFH-4 satellite should be ordered.
