    This policy was introduced for International Designation in early years
    of spaceflight by COSPAR, not by USSPACECOM or OIG at GSFC. The letter A
    should be always assigned to the (primary) payload, the following
    letters to the secondary payloads or spent rocket stages, the to debris
    etc.  Therefore it is in accordance with this policy, that BEFORE rocket
    stage separation the whole object consisting of satellite and rocket
    stage bears the ID of the satellite.
