Wireless networking systems provider, ViaSat Inc. will demonstrate the recently added capabilities of its EnerLinksIII HD (High Definition EnerLinksIII Airborne Modem Transceiver) system at the 2010 Farnborough International Airshow.
The company’s digital data links portfolio, EnerLinksIII, is now integrated with high definition video feed transmission abilities. The demonstration can be viewed from July 19-25 at the AUVSI UAV Pavilion at the Airshow.
The EnerLinksIII HD features H.264 compression can compress and transmit standard definition videos as well as high definition videos - 1080p30 or 720p60 – with a single downlink. Transmission is possible for standard definition videos of one to four streams, and high definition videos of one or two streams. With the HD upgrade, the video ISR system can transport output from highly developed infrared or optical sensors that have multiple-output capabilities – sensors are currently available in many unmanned aerial systems (UAS).
Advanced digital and compression technology integrated in the EnerLinksIII HD makes it the most capable among the ISR data links presently available in the industry. Most prevalent digital systems use proprietary methods to transport KLV metadata. EnerLinksIII HD has the ability to align into individual video frames the metadata to comply with the MISB Standard 0604.1, delivering new, elevated levels of precision and clarity.
The link’s ground component is the EnerLinksIII Ground Modem Transceiver (GMT), which, via an IP network, harvests several SD or HD video streams. These video streams can be seen on the EnerView viewer or any third party viewing or exploitation systems. Operating on L, C, or S bands, the systems offers transmission bit rates that range from 50 kbps to 11 Mbps, AES-256 encryption, and bandwidth efficient modulation.
In a recently held military demonstration exercise, the EnerLinksIII HD flew at a flight range that furthered 50 nautical miles and offered full motion HD video transmission to the ground system through the IP network and, videos were distributed to third party systems.
