The ViaSat Data Controller 850 (VDC-850) enables secure data networking using any combat net radio and handheld computer. Combat users can quickly connect this ViaSat data controller via USB to send notes and files, and run IP applications over tactical radios.

The ViaSat VDC-850 offers interoperability and flexibility for any kind of tactical mission. It features a powerful error correction algorithm to transmit images and other data over noisy half-duplex, low data-rate radio communication channels.

For error-free data sharing over native MIL-STD-188-184 and noisy radio channels, this data controller includes ViaSat eMailĀ® application software. With an intuitive, streamlined interface, ViaSat eMail application enables warfigthers to efficiently and quickly send chats, files, emails, photos, map overlays, and other documents. ViaSat Data Controller IP software is also available foroperating IP-based applications (POP3, SMTP, FTP, HTTP, etc.) over tactical radios.

Warfighters can use the ViaSat VDC-850 to transmit Cursor-on-Target core data elements for military interoperability, including direct fire mission, Blue Force Tracking, surveillance results, and airspace deconfliction information.

Lab and field tests have repeatedly verified that ViaSat Data Controllers are the highest-performance system for sending data over tactical radios. Count on the ViaSat VDC-850 to network
