Networked Digital Data Link


Networked Digital Datalink Radio

The Prescient Networked Digital Data Link (NDDL) unit employs state of the art Software Defined Radio (SDR) technology with Commercial-Off-The-Shelf (COTS) components and our unique self-organising networking algorithms to provide an integrated tactical local data network solution for aviation applications.

Software Defined Radio (SDR)
This technology is the cornerstone of many key data link systems in development and early deployment, such as the US' Joint Tactical Radio System (JTRS) . The NDDL presents a high performance yet cost-effective alternative based on COTS technologies which allows for rapid deployment and incorporation.

COTS Technologies
The Prescient NDDL maximizes the use of standard industry-grade components, coupled with modern design methodologies and manufacturing concepts, resulting in a product that is reliable, flexible and yet easy to maintain.

Self-Organising Network Algorithm
Using an external synchronization signal (e.g. GPS PPS), the module can be implemented as a tactical network data link using a Time Division Multiple Access (TDMA) protocol. In addition to the advanced RF Modulation/ demodulation features, high performance hardware such as Digital Signal Processors (DSP) and high density Field Programmable Gate Arrays (FPGA) provide tremendous processing power that allows digital filters, Forward Error Correction (FEC) and Digital Down Conversion (DDC) to be performed effortlessly within this single module.
The result is a Network Radio with a system performance that is superior to those based on traditional analog receiver design architectures.


Wide Aspect Antenna

To support the operation of the radio in training environment, a compact antenna complex with a 360 degree of coverage is available.  Made of 15 antennae, combined with the datalink radio and a control system, the antenna can control the aspect of its transmission and detection zones.
