The Ariane Passenger PayLoad Experiment (APPLE), was an experimental

Centre Spatial Guyanais near Kourou in French Guiana
.

APPLE was

SLV-3 fourth stage.[2]

It was used in several communication experiments including relay of

transponders connected to a 0.9 m diameter parabolic antenna. It went out of service on September 19, 1983. R. M. Vasagam was the project director of APPLE during 1977-1983.[3][4]
