What the DVA system represents is 'Effortless Digital', requiring only the most basic integration, and extending the mission capabilities and useful life for many TUAVs.
EL CAJON, Calif. (PRWEB) August 6, 2007
Tactical unmanned aerial vehicle (TUAV) manufacturers can use the new EnerLinks(TM)II DVA (Digital Video over Analog) system to easily transform an L/S band analog FM video communication link into a flexible digital video and IP data link. UAS video link system hardware, including transmitters, power amplifiers, antennas, and cabling, is systemically embedded throughout the airframe assembly accounting for space, weight distribution, field assembly, and even flight dynamics. Conversion to a digital data link typically represents significant systems re-engineering, cost, and time to accommodate an end-to-end digital system from the sensors, through the downlink antenna. But a simple integration of the single circuit card EnerLinksII DVA system provides all the benefits of an advanced digital data link without changing any of the UAV RF components.
"Upgrading the air platform to digital can be an expensive, time consuming investment," said Robert Varga, Enerdyne Marketing VP. "What the DVA system represents is 'Effortless Digital', requiring only the most basic integration, and extending the mission capabilities and useful life for many TUAVs."
Today's advanced data requirements for airborne ISR communications call for digital technology to provide not only IP data from video and other sensors, GPS and other telemetry, but also to deliver to the tactical warfighter the benefits of standardized video compression, link reliability, extended range performance, greater bandwidth and spectrum efficiency, and security. Yet most Tactical UAS platforms rely on basic analog FM transmitters for the ISR downlink. Some platforms even transmit vehicle metadata over an FM sideband. While these elementary systems serve a purpose, are widely available, and inexpensive, they are incapable of meeting current TUAV communication requirements in either content or format.
The new EnerLinksII DVA system provides simultaneous transmission of high quality compressed H.264 video and UDP/IP network traffic in the same bandwidth previously required to send only analog video. Using modern FEC techniques, the system delivers up to 12 dB improvement in link margin over the analog system - equivalent to a 4X improvement in range performance. Requiring less than 10 watts, weighing under eight ounces, and occupying less than 35 in(2), the DVA system needs only a 12 volt power supply and a location on the aircraft between the onboard sensors and the FM transmitter
The EnerLinksII DVA system delivers coverage to the edge of the horizon often without expensive tracking antennas. The ground system can be equipped with an optional antenna to take advantage of the built in space diversity receiver for added protection against multipath fading, in many cases doubling the range performance.
