CML introduces a maritime VDES module SDR solution

CML Microcircuits has announced it has expanded its Maritime communications product line with a new VHF Data Exchange System (VDES) module implemented using a bespoke Software Defined Radio (SDR) solution – VDES1000.

The module incorporates state-of-the-art technology that digitises the complete maritime band (156.025 – 162.025 MHz) with the majority of the processing being implemented in the digital domain. Seven simultaneous receive channels are realised along with a transmitter that is capable of 12.5 W rms (50 W peak).

VDES1000 is a complete VDES solution embedding: Automatic Identification Systems (AIS) class A, Application Specific Messaging (ASM) and VHF High Speed Date Exchange (VDE). The module can be easily upgraded with software updates to accommodate future changes in the maritime VDES standard.

CML Microcircuits has worked with the technology partner Stone Three Venture Technology based in South Africa, to develop this VDES solution. Stone Three has 15 years’ experience in developing cutting edge Digital Signal Processing (DSP) solutions and software defined digital systems. Both companies are deeply involved in IALA working groups and are committed to the development and support of the maritime VDES standard.

Tick-Tock: What Your Engineers Could be Spending Time Doing if They Weren’t Stuck Designing a Display?
As soon as any design project is embarked upon, the clock starts ticking. The length of time needed to develop a system can impinge heavily on its commercial success. Windows of opportunity could be missed if it takes too long to complete, with products from rival companies gaining greater market share.
