I do 250 mbits on 21 transponders :) ----- Original Message ----- From: John van Oppen <john@vanoppen.com> To: Chris Adams <cmadams@hiwaay.net>; Deepak Jain <deepak@ai.net> Cc: nanog@nanog.org <nanog@nanog.org> Sent: Tue Jun 02 14:51:59 2009 Subject: RE: Fiber cut - response in seconds? Ok, while this is off-topic, let's just point people to Wikipedia: Other satellites (which are NOT in the same position at all times from the prospective of a spot on earth): http://en.wikipedia.org/wiki/Geosynchronous_orbit TV, and other fixed positioned (relative to the earth are geostationary): http://en.wikipedia.org/wiki/Geostationary_orbit perhaps further comments can go to the discussion pages on Wikipedia since I would wager a very small number of us push any serious number of bits via satellite.

I promise you that that is not the case for all applications. Geosynchronous satellites can be anywhere. For the applications you are considering (communications mostly), equatorial orbit is the most advantageous.

Geosynchronous are only over a particular longitude. They move up and down in latitude, so it isn't over a given point except twice per day (or only once at the extremes). -- Chris Adams <cmadams@hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
