Enerdyne Technologies Inc., a ViaSat company, has successfully demo'd its DVA (Digital Video over Analog links) technology interoperating with a ROVER video receiver. 

The DVA allows low-cost conversion of the video link between an aircraft or Unmanned Aerial Vehicle (UAV) transmitter and a ROVER receiver to a digital link encrypted with AES-256. With an installed base of nearly 8,000 units, the ROVER is used in a variety of combat applications to receive analog FM video transmitted from many Unmanned Aerial System (UAS) platforms, such as Predator, Shadow, and Hunter UAVs. But these analog signals are easily intercepted by enemy combatants using simple, readily available receivers, potentially compromising missions and endangering U.S. troops.  Enerdyne’s DVA technology can prevent such eavesdropping by upgrading a ROVER analog link in L-, S- or C-band to a secure digital data link encrypted with AES-256. Enerdyne is repackaging its DVA receiver to provide an appliqué unit that can be attached to a ROVER in the field without the use of tools.  Installation will take less than 60 seconds.  The appliqué unit is scheduled to be available in four months. The Enerdyne DVA unit for the aircraft has been in production since June 2008.
