Carlsbad-based satellite and wireless networking developer ViaSat said earlier this week that it has acquired the assets of Gray Labs, a developer of high rate modem products and custom spacecraft technologies for earth observation. Financial terms of the deal were not disclosed. Gray Labs was based in Duluth Georgia. According to ViaSat, it will continue to support Gray Labs products and customers from Georgia. ViaSat said the move would help it expand its high-speed satellite data communication technology.
