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 , Walter Nissen wnissen@tfn.net -81.8637 , 41.3735 , 256m elevation --- Power corrupts . Absolute power corrupts absolutely .
