CapRock Government Solutions of Fairfax, Va., recently won four U.S. government contracts worth more than $47 million combined for satellite communications bandwidth and network management services, according to a company press release.

CapRock will provide 400 megahertz of Ku- and X-band capacity and the associated teleport and backhaul services to the unidentified government customers through 2013, the press release said. The contracts, awarded in May and June, increase the total amount of bandwidth CapRock is providing to the U.S. government by about 11 percent, to 4 gigahertz spread over 63 satellites, the press release said.

The satellite networks will support a wide range of activities including tactical field communications and airborne intelligence, surveillance and reconnaissance. The capacity will be provided by satellites operated by EchoStar Satellite Services of Englewood, Calif., Eutelsat of Paris, Paradigm Secure Communications of the United Kingdom, and SES World Skies of Princeton, N.J.
