narramissic writes "ITworld is reporting that the Department of Defense plans to launch in the first quarter of 2009 a satellite-based router to deliver military communications. Satellite operator Intelsat will manage the three-year Internet Routing In Space (IRIS) project, while Cisco will provide IP networking software for the on-board router. After testing, the satellite will be available for commercial use. From the article: 'Potential nonmilitary benefits of the IRIS program include the ability to route IP (Internet Protocol) traffic between satellites in space in much the same way packets are moved on the ground, reducing delays, saving on capacity and offering greater networking flexibility, Lloyd Wood, space initiatives manager in the Global Defense, Space & Security division of Cisco, said Thursday.'"

The article didn't say it was going to be in geostationary orbit. Don't assume that just because a geostationary satellite internet satellite has 650ms pings that all satellites will.
A satellite could orbit as low as 100 miles.

Speaking of which, how DO they manage "realtime" data on that w/o the lag? It wouldn't exactly be true realtime if ~250ms delay keeps chucking in there. While that may be no biggie now, I can see where that would/could be a factor as real battlefields become just as data-dependant as the game ones. (cue lots of "haha, you got pwned by the Chinese!" jokes here, but seriously... I wonder how they're going to eventually get around that; the physics would be gnarly at best...)

The new system will be
source - satellite #1 - space router - satellite #2 - destination
or even better
source - space router - destination
Depending on where the satellite is, you may have just shaved a few tenths of a second off the one-way trip.

Re:What do I know about it? (Score:4, Informative)
Currently the RF links use multiplexed frames with different PN sequences and frame sync headers to communicate, so the position of each bit within the frame means something.
With IP packets, we wouldn't really have to decode/demux the frames to get the information. Each entity could send data based on its IP address. As mentioned before - the lag time issue is gonna be pretty messy, unless we used UDP or something similar. We are just in the beginning stages right now for our purposes, so just configuring the routers and getting the data into an RF link and be errorless is what we are fighting.
Hope that sheds some light on why. Also - the frequencies we are talking about are going to be S, K, Ku, Ka, and higher, so it isn't likely that a script kiddy will have access to that kind of equipment. Also - the links will be encrypted and PN spread, making it less likely to be intercepted/hax0r'd...
