Data Controller 550
Router data controller for networking tactical radios
The ViaSat Data Controller 550 (ViaSat VDC-550) enables secure data networking using any combat net radio, linking warfighters on the tactical edge to the Common Operating Picture. Run net-centric web applications, send error-free data, and employ TCP/ IP services over existing radios, even over severely degraded radio channels.
Acting as an IP network interface, the ViaSat VDC- 550 overcomes half-duplex issues and is field-proven to handle IP connectivity on a variety of challenging radio channels including UHF satcom, UHF line-of-sight, VHF, HF and wireline channels. Additionally, it bundles IP packets for more efficient (less bursty) transmissions. With two ViaSat VDC-550s you can route IP traffic over a radio subnet, forming a bridge over the radio link between two LANs.
This data controller also uses native MIL-STD-188-184 for fast and reliable data transfer across existing radio links. It supports networks of up to 64 users per channel with point-to-point, multicast, and broadcast messages. Using powerful error correction techniques, it sends data over poor quality channels*.
The ViaSat VDC-550 can act as a gateway between TCP/IP networks and MIL-STD-188-184 networks. It works together with existing LAN-based mail and file servers to provide mail and FTP services to a network of VDC end point users who are using the ViaSat eMail® application software. The ViaSat VDC-550 is fully interoperable with current and legacy ViaSat Data Controllers.
