About Us

Welcome to the website of The Real-Time Data Company Ltd.


An established and respected supplier of test & verification equipment and services

The RTDC has a long history in the design, manufacture and support of evaluation and testing (E&T) equipment and services for major programmes. This includes developing E&T strategy and plans for all stages through to trials, as well as designing and building bespoke equipment and real-time recording systems. Our specialist multi-disciplinary engineering team, with the necessary support services, developed our products and services including planning and undertaking sea trials of multi-sensor systems. Radar, EW, sonar, infrared line-scan (IRLS) as well as other electro-optic visual imagery are typical of these high-speed sensors and sensor systems.

Staying at the leading edge, with a change in direction

Many of these projects include high-speed recording with ‘quick-look’ processing of data during bench testing or field trials. The ‘quick-look’ facility is essential to avoid expensive, but nugatory work, if unexpected incidents occur. In-depth analysis, or data reconstruction with accurate cross-channel correlation, are important features of post-recording replay.

Reasons to get in touch…

Projects include support for Eurofighter Typhoon, Gripen, GlobalEye,and Nimrod plus a Tornado EO/IR reconnaissance pod and an EW airborne radar system. We have also provided equipment for ErieEye, AMSAR, CECAR, Rapier, ALARM and many others including several naval projects. We have produced E&T high speed data recording systems for SeaKing and SeaSpray Radar systems and for the ASTRAEA UAS programme. Satellite downlink data burst transfers are also in our portfolio. Typically, these are for radar, visual or magnetic signature applications.


Our experience has shown that there are many similarities between these systems. It has also become clear that more effective pre-trial testing reduces the cost of equipment trials.
In 2009 we undertook company-funded research, in collaboration with University College London (UCL) and an EPSRC grant, into how to undertake more effective E&T. This research proved very effective and The RTDC participated with three prime contractors (initially BAES, Thales, QinetiQ) in a dstl-funded technical demonstrator project SimTE (Simulation for Test and Evaluation). SimTE employed an E&T process, based upon User approved Use Cases. It was driven by a synthetic real-world environment plus interface equipment to stimulate the equipment under test. Interchange of software and hardware modules in the equipment under test showed that the E&T process was applicable for both. More information is available for those who register their interest on the LET’S page.
In parallel, The RTDC developed a mini-system more suitable for small-medium companies to own and operate. It uses a simpler synthetic environment based upon PC architectures, FPGA, and other processing to generate signals to interact dynamically with the equipment under test. It demonstrated that it is possible to undertake much ‘real-world’ testing in the laboratory, thereby reducing the risk and cost of trials.
Furthermore, the combined work showed that it is practical to freeze requirements at the start of system design and re-use them in an E&T process that covers the lifecycle of each project. The ability to collect the same metrics, in a way that does not change throughout the life of a project, makes it much simpler to control a project.


The RTDC’s current focus is to step back and take a wider view. There is potential to create a new market in this area. We want to engage with other organisations to explore these opportunities. We hope that you will join us.
