V-Track™ · V-20 INFORMER™

The V-Track™ V-20 Informer™ is an AIS information provider and remote monitoring system for use on marine aids to navigation (AtoN) and other structures. The V-20 Informer™ is available in two options: “Type 1” is a transmit only device, and “Type 3” is a transmit and receive device that can be configured over the air and has chaining functionality. For most applications a transmit only device provides the ideal AIS AtoN solution.

The V-20 Informer™ is a compact unit housed in a rugged environmental enclosure for use on any AtoN. With a power consumption of less than 0.09Ah/day for a Type 1, the V-20 Informer™ is suitable for solar installations, including buoys anywhere in the world. Tideland Signal has adopted the emerging IEC standards defining the functions and message structure contained within the AIS AtoN message. The V-20 Informer™ complies with IEC and ITU requirements and also IALA recommendations. It has the following approvals: Industry Canada, R&TTE, BSH, FCC.

In addition, both the Type 1 and Type 3 V-20 Informer™ have optional remote monitoring capabilities. It is capable of remote monitoring almost any manufacturer AtoN. When monitoring a Tideland Signal lantern the standard system provides lantern status, battery voltage (loaded and unloaded) and an extra available input. The V-20 Informer™ broadcasts AtoN message 21 and also has the capability of broadcasting meteorological, hydrological and remote monitoring data.


    There are situations that require the authorities in charge to create either virtual or synthetic aids to navigation using their existing AIS infrastructure. For these cases, the V-20 Informer™ is ideal as it supports both virtual and synthetic AtoN.
    The V-20 Informer™ is supplied with a comprehensive software application that enables the user to program the unit via an optional USB interface.
