The launches of the first 2 satellites was bought from Ariane 5 in July 1997. The order was cancelled in May 1998 because of the unability to deliver the satellites in inclined orbit. The Ariane 5 vehicle would not have been able to place these craft in orbit until the advent of the new launcher's reignitable upper stage in 2001. As the prime contractor, Loral (which delivers the satellite in orbit) will try to use the 2 vacant ariane slots or will have to pay 6% of the $290 million contract.

With inclined satellites, 3 satellites are required to make the system operational. The fourth satellite will serve as a ground spare (this will cost an additional $290 million).

In Aug 1997 Loral announced to have invested $25 million in CD Radio (approx 15%) The total system cost is now approx $950 million
