Launch site	Ko, ELA-2
Launch vehicle	Ariane-44LP (V122)
Operator	Orion Atlantic L.P.
Mission	Telecommunications
Geostationary orbit:
Location	15°W

In order to solve the co-location problem around 15°W (originally 12.5°W) 4 54-MHz transponders were exchanged with Eutelsat. Eutelsat agrees not to use its 14.8°W reservation in return.
