i-VDE-BS4 VDES AIS Base Station
The i-VDE-BS4 VDES AIS Base Station is indeed a complete analog of the R60 VDES Base Station. Both are designed to perform similar functions within the framework of VHF Data Exchange System (VDES) and Automatic Identification System (AIS) communications.
Also the i-VDE-BS4 VDES Base Station/AIS Base Station has a Secure AIS support function for encrypted communications.
PROVEN FIELD EXPERIENCE
The i-VDE-BS4 VDES Base Station represents the evolution of the highly regarded i-ais-BS1 AIS Base Station, known for its unwavering quality and dependable performance.
The i-VDE-BS4 VDES AIS Base Station from iMarine is a VDES-compliant base station that integrates AIS and ASM functionalities. The i-VDE-BS4 VDES Base Station complies with the key international standards, including the VDES standard, AIS Base Station Standard IEC 62320-1, AtoN Standard IEC 62320-2, and AIS Repeater Standard IEC 62320-3.
As a core component of a Physical AIS Shore Station/Base Station, as defined by IALA, the primary function of the i-VDE-BS4 VDES AIS Base Station is to facilitate data exchange with AIS/VDES-equipped vessels within its coverage area. It can be deployed as a stand-alone unit or integrated into a broader network.
The i-VDE-BS4 VDES Base Station, iMarine’s cutting-edge base station, is purpose-built for both fixed shore and offshore setups. It offers robust support for the latest VDES standard, encompassing traditional AIS functionality while introducing an impressive array of innovative features.
The i-VDE-BS4 VDES Base Station is purposefully crafted to adhere to the upcoming generation of maritime communication protocols. It seamlessly supports traditional AIS, the powerful ASM channels (Application Specific Messaging), and the emerging VDE channels, aligning perfectly with ITU VDES recommendations and the VDES guidelines set forth by IALA.
What is VDES?
VHF Data Exchange System (VDES) is a radio communication system that operates between ships, shore stations and satellites on Automatic Identification System (AIS), Application Specific Messages (ASM) and VHF Data Exchange (VDE) frequencies in the Marine Mobile VHF band.
What is the difference between VDES and AIS?
AIS is a component of VHF Data Exchange System (VDES) which operates using the Gaussian Minimum Shift Keying (GMSK) modulation scheme, other components of VDES will use higher capacity modulation schemes.

Why VDES?
The VHF Data Exchange System (VDES) is seen as an effective and efficient use of radio spectrum, building on the capabilities of AIS and addressing the increasing requirements for data through the system. New techniques providing higher data rates than those used for AIS is a core element of VDES. Furthermore, VDES network protocol is optimized for data communication so that each VDES message is transmitted with a high confidence of reception. VDES supports e-Navigation and provides access to the Maritime Cloud.
What frequencies does VDES use?
VHF Data Exchange System (VDES) comprises a suite of channels in the Maritime mobile VHF band, which are detailed in the IALA VDES Guideline on the IALA website [read more]
