Detailed description

The AMEC B620WS AIS Class B transponder is a communication and safety solution designed for recreational boats and small fishing vessels. This device combines a CSTDMA AIS transponder with Wi-Fi connectivity and an integrated VHF antenna splitter, providing enhanced visibility and simplified integration aboard.

AIS Performance and Marine Visibility

Operating under the CSTDMA (Carrier-Sense Time Division Multiple Access) access scheme, the B620WS transponder transmits your vessel’s static and dynamic data with a transmit power of 2 watts (+33 dBm). It operates within the AIS frequency range. Dynamic data is broadcast every 30 seconds when speed exceeds 2 knots, and every 3 minutes at speeds below 2 knots or when at anchor, improving situational awareness at sea.

Integrated and Versatile Connectivity

The B620WS integrates a Wi-Fi module, allowing AIS data to be shared with smartphones, tablets, or laptops over a frequency range of 2.412 MHz to 2.472 MHz (transmit power ≤ 20 dBm (EIRP)). A VHF antenna splitter is also included, simplifying installation by sharing a single VHF antenna for AIS and radio. For complete integration with navigation systems, the transponder is equipped with NMEA 0183, NMEA 2000, and USB interfaces. It supports a wide range of NMEA 2000 PGNs for transmission and reception, as well as NMEA 0183 sentences such as GGA, GSA, GSV, GLL, RMC, VDO, VDM, DTM, GBS, HDT, and ROT.

Accurate and Robust GNSS Receiver

Featuring an integrated GNSS receiver, the B620WS is compatible with GNSS systems. The device is built to withstand demanding marine environments, with dimensions of 151.22 x 128.57 x 49.87 mm and a weight of 400 g. It is tested for robustness against shocks, vibrations, extreme temperatures (-25 °C to +55 °C), and salt fog.

Compliance and Safety

The AMEC B620WS AIS transponder complies with rigorous international standards, including IEC 62287-1 for AIS performance, IEC 61108-1 Ed. 2.0 for GNSS, and IEC 60945 Ed. 4.0 for environmental conditions.

Expert opinion

« AMEC B620WS : L'AIS Classe B CSTDMA polyvalent avec Wi-Fi et splitter intégré »

Le transpondeur AIS Classe B AMEC B620WS représente une solution intégrée pour la sécurité des petits navires de plaisance et de pêche. Sa valeur d'usage réside principalement dans sa capacité à améliorer la conscience situationnelle en mer, permettant aux navires équipés de visualiser et d'être vus par d'autres embarcations dotées d'un système AIS. L'intégration du Wi-Fi est un atout majeur, facilitant la diffusion des données AIS vers les dispositifs mobiles à bord, réduisant ainsi le besoin d'un multiplexeur ou d'une passerelle Wi-Fi externe. Cette fonctionnalité est particulièrement pertinente pour les équipages utilisant des tablettes ou smartphones comme écrans de navigation secondaires.

L'intégration d'un répartiteur d'antenne VHF est un facteur de simplification significatif pour l'installation. Il permet d'utiliser une seule antenne VHF pour la radio VHF et l'AIS, ce qui réduit l'encombrement, le câblage et le coût d'une antenne dédiée. Les multiples interfaces (NMEA 0183, NMEA 2000, USB) offrent une flexibilité d'intégration étendue avec la plupart des traceurs de cartes et MFD (Multi-Function Displays) du marché. Le récepteur GNSS intégré garantit une source de positionnement fiable et précise, essentielle pour la transmission des données AIS.

Cependant, il est crucial de noter que le B620WS est un transpondeur AIS Classe B CSTDMA. Sa puissance d'émission de 2 Watts et son taux de signalement dynamique (toutes les 30 secondes au-dessus de 2 nœuds) sont inférieurs à ceux des systèmes AIS Classe A ou Classe B SOTDMA (5 Watts et taux de signalement plus élevés). Cela signifie que sa visibilité peut être légèrement réduite dans les zones à fort trafic ou sur de plus longues distances par rapport aux systèmes plus puissants. Pour les navires de plus grande taille ou ceux naviguant dans des zones commerciales denses, un transpondeur Classe B SOTDMA ou Classe A pourrait être plus approprié, mais pour la plaisance et les petits navires, le B620WS offre un équilibre optimal entre performance, intégration et coût.

Frequently Asked Questions

Need help? Contact us

What type of AIS transponder is the B620WS and what is its transmission power?

The AMEC B620WS is a Class B AIS transponder using the CSTDMA (Carrier-Sense Time Division Multiple Access) access scheme. Its AIS transmit power is 2 Watts (+33 dBm).

What are the connectivity options of the AIS transponder B620WS with existing navigation systems?

The B620WS transponder provides extended connectivity through multiple interfaces:

NMEA 0183: For connection to devices compatible with this standard. NMEA 2000: For easy integration into an NMEA 2000 network. USB: Enables connection to a computer for configuration or data transfer. Wi-Fi: Allows wireless sharing of AIS data with smartphones, tablets, or laptops.

Do I need a separate VHF antenna for the radio and for AIS with the B620WS?

No, the AMEC B620WS transponder includes a VHF antenna splitter. This allows you to share a single existing VHF antenna between your VHF radio and the AIS transponder, simplifying installation and reducing the number of antennas required aboard.

Which satellite systems does the integrated GNSS receiver in the B620WS support?

The AMEC B620WS transponder is equipped with a 72-channel integrated GNSS receiver that supports multiple satellite positioning systems for optimal accuracy. It is compatible with:
