Hi Roger,
Some friends of mine make a data logger/tranceiver specifically for the Iridium constellation which was originally designed for sending oceanographic data but more recently has been used by the likes of Ellen MacArthur for sending position and status data back to base. I don't know about the prices charged but I suspect that it would be way cheaper than full voice modems because their system transmits messages that may be restricted to only 1960 bytes!.
Give them a call, their contact details can be found at http://www.tridentsensors.com/index.html or e-mail Helen Cusens at info@tridentsensors.com
For those Brits reading this, Trident sensors have their offices in the control tower at Dunsfold Aerodrome where Top Gear is filmed, so if you go to visit them you are likely to see some pretty wierd stuff going on alng the runways!
Good luck
Quentin
