All our current systems have been developed to be compliant with NATO STANAG 5030 Edition 4. Drumgrange is now developing products to be compliant with the new NATO STANAG 4724 which is currently being ratified by NATO member states.
To aid system development, Drumgrange has developed a sophisticated numerical (Matlab/Simulink) modelling environment to support link budget estimation and overall system performance analysis.
We work closely with CESG, the UK Government's National Technical Authority for Information Assurance, during the development and security accreditation of High Grade devices required within these programmes.
In addition to the UK sovereign programmes, Drumgrange also provides VLF/LF Communications equipments to NATO Facilities and for other overseas national programmes.
Products
MSK Demodulators (DDM311)
Designed to meet all the requirements of NATO STANAG 5030, the compact DDM311 enables the continuous off-air data recovery of MSK and FSK from up to five separate VLF radio receivers and 20 data channels simultaneously. In service with NATO, versions are available for onboard naval use to upgrade existing VLF/LF receivers for multichannel MSK service.
VLF/LF Multimode Transmitter Drives (DDR310)
DDR310 enables up to 4 x 50 (or 75) baud keystream data inputs to be formatted and modulated onto a high-stability LF/VLF carrier. The modulated carrier is then passed to the associated transmitter power amplifiers. Versions that incorporate extended or remote control and automatic antenna fine tuning are available. Comprehensive built-in test circuits are included in the design.
