Radio Modem Operational at QinetiQ

QinetiQ wished to undertake a major update of the data gathering and control part of the instrumentation. For operational reasons it was essential that a wireless control system be installed that would operate in the challenging environment of the relatively shallow water (5.5m) concrete basin, within an enclosed structure, complete with facilities such as rotating arm and wave making machinery.

WFS was approached as it was recognised that an electromagnetic solution would operate in an enclosed environment, immune from the presence of acoustic noise. In addition it could handle the required data rate with no systemic delay in transmission and with a high degree of reliability.  It would also have the key benefit of control data seamlessly crossing the water/ air boundary in both directions. The WFS S1510 Radio Modem, optimised for the Ocean Basin application, was proposed, selected, and is currently being commissioned.

The above surface Radio Modem is now being integrated with the facility Control Desk and the control software for the model under test. The underwater Modem, with its loop antenna is being integrated into the test model submarine. The system will be used to control the Model underwater with comprehensive error correction checks. Speed and depth information will also be telemetered back to the Controller.
