Data Distribution Unit (DDU)
The DDU uses a combination of hardware and software to enable
centralized interaction with platform C4ISR, EW and weapons
subsystems. The DDU is based on a modular design that uses
industry standard interfaces and protocols. This enables the DDU
to be seamlessly integrated into current C4 platforms to aggregate
disparate subsystems via a single operator interface that provides a
Common Operational Picture.
DRS’ integrated systems approach allows data to be disseminated
across the network in near-real-time to other platform workstations,
adjacent units and higher headquarters.
The DDU provides the following additional capabilities to enhance
tactical platform C4ISR with significant reductions in
Size, Weight, Power and Cost:
Tactical Router - The DDU is a fully capable data router and
Ethernet switch, interconnecting on-board IP capable equipment and
off-platform networks using a variety of available interfaces. Optional
embedded 802.11 available.
Voice Cross Banding and Call Management - The DDU is a radio
agnostic gateway that interfaces to analog and digital voice radios.
It provides a decentralized management service that enables
cross-banding of any connected radio. The DDU also seamlessly
interoperates with COTS VoIP devices and infrastructure using the
SIP protocol. Optional embedded cellular GSM/CDMA available.
Tactical Server - The DDU has the computing horsepower to support
native and end user services and applications. Virtualization on the
DDU allows concurrent operation of these additional services, even
if the applications require multiple different underlying Operating
Systems such as Windows and LINUX.
Network Video Distribution - The DDU accepts up to four (4)
analog RS 170 video feeds and converts them to digital video for
distribution on any attached LAN/WAN interface. The DDU also
distributes protected video using a forward error correction protocol
to accommodate packet loss often seen in highly mobile networks.
This video is multicast across the network and made available
to any number of receive locations. The video can also be user
selected and stored locally or remotely.
Peripheral Control, Radio Management, and Sensor Interfaces - The
DDU hosts a software GUI that can control a variety of peripherals,
radios, and sensors through any connected workstation without
requiring the operator to physically manipulate the device.
GPS Distribution - The DDU accepts and distributes single source
GPS data and makes it available to any connected device on the
platform, eliminating the need for multiple GPS devices. The DDU
can also host an embedded GPS SAASM to eliminate the need for
an externally connected GPS device.
Rugged and qualified to MIL STD 810G, the DDU is fielded and
operates in the most extreme tactical environments. The modular
design of the DDU provides significant growth capacity and available
I/O to accommodate emerging requirements for new platforms,
essentially making the DDU “Future Proof”.
