Maritime VHF data exchange system capable of 12.5W rms

 

Designer, developer and supplier of RF, low-power analogue, digital and mixed-signal semiconductors for wireless communications systems, 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 technology that digitises the complete maritime band (156.025-162.025MHz) 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 12.5W rms (50W 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. Both companies are deeply involved in IALA working groups and are committed to the development and support of the maritime VDES standard.
