But you'll need to talk to the satellite service provider to find out which modems will work. Power requirements will depend a lot on where the satellite is --- is it a geostationary comms bird (don't need to move the antenna after it's set up) or a set of orbital satellites (that you need to track)? The latter can need less tranmitter power (they're closer to the earth) but may need more to steer the antenna, or a more costly phased array that can be steered electronically. I know there are some embedded satellite products (I think Avtec make one for unattended weather stations that runs Linux) but don't know much about them. I do know that if you have to go via a geostationary sat., the delay is long enough to need special TCP parameter tuning for decent performance. -- Dr Peter Chubb http://www.gelato.unsw.edu.au peterc AT gelato.unsw.edu.au http://www.ertos.nicta.com.au ERTOS within National ICT Australia -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
