I don't have any solid figures but the images at http://www.satellite.eu.org/image/iridium_construct.gif http://www.satellite.eu.org/image/iridium_construct2.gif might lead you to a guesstimate (perhaps 2.5 m length for the antennae, ~3m for the solar arrays and ~4m for the satellite bus itself, with widths of ~1m)? regards, -- Neil Clifford <neil@satellite.eu.org> http://www.satellite.eu.org/satintro.html
