Communications
Astra 1B was the second of the Astra communications satellites launched and operated by SES (Société Européenne des Satellites). It was believed to have been launched in a faulty condition, and suffered a thruster failure early in its life, causing minor drift, meaning that it became permanently difficult to obtain a steady lock on the satellite. This was most notable on analogue transmissions where the picture would move from clear to carrying sparklies and back again.

The Guiana Space Centre is a European spaceport to the northwest of Kourou in French Guiana, a region of France in South America. Kourou is located at a latitude of 5°. In operation since 1968, it is a suitable location for a spaceport because of its equatorial location and open sea to the east.
