    Greetings , all ,
    
    Below is a diagram showing the current status of the Iridial
    constellation , using what are believed to be the only known unambiguous
    names for these satellites .
    
    There are 11 operating satellites in each of 6 planes ,
    designated P0 through P5 .
    The objects are numbered 0 through A in each plane .
    The objects follow one another across the sky in numerical order ;
    so do the planes .
    An R , Q , etc. , is appended to each satellite which has replaced
    another .
    Spare satellites are similarly designated B , C , etc.
    Many failed satellites are designated S , T , etc.
    Horizontal positioning of the name indicates its placement within or
    between planes .
    
    Thanks to Mike McCants , Ted Molczan , and Rod Sladen for their 
    assistance .
    
    Cheers ,
