Gilat Satellite Networks, are both a service provider & a Manufacturer.

see www.gilat.com under the Skyblaster section, This is a modification of the Skysurfer System, but using DVB technology as oposed to thier own bespoke architecture.

The system is curently NT Based, I do not know if they ar planing a linux version. However I think the Recive card is based upon the Broadlogic Satellite Express Cards www.broadlogic.com which which do have Linux Drivers.

The return path is a gilat proprietry system, which I belive requires a costly hub based at the uplink.

I have sucessfully built a linux based router, using a Broadlogic DVB Receive card for the High speed satellite receive. One ethernet board for the local lan, and another used as a return path connected to a standard satellite modulator via an ethernet bridge. The Hub site is built using a router a DVB IP Encapsulator, and a bank of recievers with ethernet bridges.

There are companies that are building comercial versions of the system described above, but when I was last working on this project none of them had implemented any satellite return path, hence the ethernet bridge setup.
