Actually, Mike McCants seems to have taken this matter into consideration and adopted some slightly more descriptive "common" identifiers in the elements that he posts on his Web page. These help differentiate between the known tumblers, those suspected of having attitude control problems, those still being manuevered to operational altitudes, and those which USSPACECOM has mixed up. Mike's system works for me... :-) TTFN, Geoff +=========================================================================+ | Geoff Chester grc@spica.usno.navy.mil Public Affairs Office | | US Naval Observatory | | (202) 762-1438 3450 Massachusetts Avenue, NW | | (202) 762-1516 (FAX) Washington, DC 20392 | |-------------------------------------------------------------------------| | "Each passing hour brings the Solar System 43,000 miles closer to the | | globular cluster M13 in Hercules; yet there are still some misfits who | | insist there's no such thing as progress!" -- Ransom K.

Or was it Iridium 20? There is some confusion here and I would like to propose a solution. In the case where the USSPACECOM name does not match that given by Iridium LLC (or whoever), list the USSPACECOM name first and some short version of the true name in parentheses. So: Iridium 18 (SV20) Iridium 46 (SV24) I have chosen the USSPACECOM name as the primary identifier since that is the only name that most of us can get our hands on. The term SV (space vehicle) is nice and short. Any comments? Randy
