1975-077A
The Symphonie 2 (MV2) satellite built by the CIFAS/Aerospatiale consortium for CNES and DFVLR was launched in Aug 27. It joined MV1 at 11.5W. Space Command elements were not released for much of 1985, but it appears that the orbit was raised to 1440 minutes in the third quarter of that year and the satellite was presumably decommissioned at that time.
