i-Marine i-ais-WTA Advanced WAIS Transponder is a Class-A AIS mobile device, which provides WAIS functionality in addition to the standard AIS features.
Warship functionality over standard Class A features mainly includes additional operating modes, spoofing capability and extension of standard VHF marine band for operation (VHF-P frequencies).
i-ais-WTA can conceal the standard (real) identification, type and position information, where required, and produces a set of fake data (position offset, false identity, fake type, fake echo, reduced signal power, etc.) to transmit from standard AIS channels. While in spoofing mode; the real AIS data is broadcast in encrypted format while the fake AIS data is broadcast as standard, unencrypted AIS messages. The operator can de ne fake scenarios or information for up to 10 vessels, using different approaches (Offset / Delayed / Pre-planned Route).
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 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, 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.
