EnerLinksIII™ HD - Multichannel High Definition Compression in a Full Duplex Data Link
The EnerLinksIII™ HD has raised the bar for advanced performance tactical airborne ISR data links with the addition of integral H.264 compression for multiple High Definition (1080p30 or 720p60) video feeds.
The High Definition EnerLinksIII Airborne Modem Transceiver (AMT HD) can simultaneously compress and transmit 1 or 2 streams of High Definition video or 1 to 4 streams of Standard Definition video over a single downlink.
With air-to-ground IP connectivity and MISB-compliant KLV metadata handling, EnerLinksIII HD is the only ISR data link ready to work with today's advanced multiple-output Electro Optical (EO) or Infra Red (IR) sensors.
Compliance with industry standards for data interoperability has been a key component of the EnerLinks product family.
While other digital systems may transport KLV metadata using proprietary methods,
the EnerLinksIII HD can align the metadata to individual video frames in accordance with MISB Standard 0604.1.
Following in the EnerLinks legacy, the AMT HD is I/O rich, with interfaces for TCP/IP or UDP/IP over Ethernet,
two HD-SDI digital video ports, four NTSC / PAL analog video ports, multiple high-speed serial ports, two dedicated GPS ports, and two-way audio.
The flexible I/O capability of EnerLinksIII HD allows the system to serve both as an ISR link and as a payload and vehicle control link,
minimizing equipment size, weight, power, bandwidth demand and antennas.
The system operates in L, S or C band and provides user selectable transmission bit rates from 50 kbps to 11 Mbps, bandwidth efficient modulation, and integral AES-256 encryption.

EnerLinks™ Autotracking Antenna System
Enerdyne's autotracking antenna system is a rugged, portable, fully integrated system that enhances the range performance of the EnerLinksIII™ full duplex digital data link. A 24" parabolic reflector antenna provides a constant link margin with frequency. The antenna system is configurable for L/S, or C band. Antenna gain varies from 18dBi at 1.7GHz to 28 dBi at 5.5 GHz and the narrow beam width improves theatre wide spectrum efficiency. Tracking is performed using a combination of GPS and signal amplitude. Tracking algorithms reside in the EnerLinksIII™ Ground Modem Transceiver (GMT), eliminating the need for a dedicated tracking unit. For close range, an omni antenna integrated with the GMT's diversity receiver provides seamless switching for continuous link performance.

EnerLinks™ AES-256 Encryption
Enerdyne's AES implementation adds commercial grade encryption using a 256 bit key to the EnerLinks™ family of advanced video ISR digital data links.
AES is an encryption algorithm routinely used to protect classified government and vital commercial transactions including banking and financial data
and is well suited to secure the line-of-sight (LOS) ISR downlink from Unmanned Aerial Vehicles (UAVs) for almost all missions. On their own, digital
data links add a level of complexity with multiplexing and forward error correction that can neutralize incompatible receivers. The addition of AES-256
compression completely secures the link.
The AES option for the EnerLinksII® DVA (Digital Video over Analog links) is available now. The DVA has the unique ability to convert any analog FM
data link to an advanced digital link by simply inserting the DVA module between the UAV's sensor and FM transmitter. On the ground, analog FM receivers
can feed their baseband output to an EnerLinksII® DVA Ground Modem Receiver (GMR-DVA) for data recovery and decryption. The GMR-DVA outputs analog video
to drive a standard monitor as well as digital compressed video over Ethernet that can be viewed by software running on a PC. Integration of these
systems can be accomplished in the field by maintenance technicians.
Key features of Enerdyne's implementation are:
• Encryption is applied to all user data as a single data stream
• Follows FIPS requirements
• Password is optionally stored in either volatile or non-volatile memory
• All keys and passwords can be erased through a software command
• Encryption does not impact latency or data throughput
The AES-256 option can be added via a simple software download in the field or depot and is supplied on CD-ROM media.

EnerLinksIII™ - Software Defined, Full Duplex, Digital Data Link
The EnerLinksIII™ is an advanced digital data link transceiver optimized for high bandwidth ISR applications in Tactical Unmanned Aircraft Systems. It is designed to address several key communications issues related to both ISR payload data and the UAS command and control. EnerLinksIII™ is a fully integrated system that in one small airborne package includes:
• Two channels of video compression,
• Efficient data multiplexing from sensors, IP traffic, metadata, and serial ports,
• Reliable link performance using Turbo code FEC, and interleaving,
• Waveform options for performance, and interoperablility.
The EnerLinksIII™'s native GMSK modulation is spectrally efficient, allowing more UAVs to operate within the same frequency band. It also supports the use of power efficient class C amplifiers. Its inherent programmability can support requirements for other waveforms such as CDL or COFDM. Used with small tactical antennas in the aircraft and on the ground, EnerLinksIII™ can deliver reliable link performance to the horizon.

EnerLinksII® DVA - Effortless Digital Over Analog Links
The EnerLinksII® Digital Video Over Analog (DVA) system is a unique digital data link for operational Tactical Unmanned Aerial Systems. This full duplex, all digital system converts the existing L/S band analog FM video communications link found in most Tactical UAV's into a robust, flexible digital video and IP data link while utilizing the existing airframe ISR transmitter, power amplifier, filter, and antenna. It provides all the benefits of an advanced digital data link without changing any of the UAV RF components, virtually eliminating concerns over re-engineering and replacement of tested and qualified sub-systems.
The 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, and by using modern FEC techniques it achieves up to 12 dB improvement in link margin over the analog system - equivalent to a 4X improvement in range performance.
