Subsonus Tag

Cost-effective acoustic positioning transponder

Subsonus Tag is a low cost acoustic positioning transponder that operates with the Subsonus USBL system. In addition to tracking underwater unmanned vehicles such as AUVs and ROVs, it provides remote sensing of position, orientation, heading and temperature. It features an integrated battery, wireless charging and a pressure-tolerant display. Ultra-low power consumption allows operation for up to 18 months on one charge. Up to 65,000 Tag underwater transponders can be tracked by one surface Subsonus unit.

Description

Ultra-Long Battery Life

Subsonus Tag introduces a revolutionary acoustic processing architecture that delivers an unparalleled battery life of up to 18 months for slow update applications. Its configurable transmit power enables extended battery life when operating at close range.

Multi-Track Technology

With the capability to deploy and track up to 65,000 Subsonus Tags simultaneously in the same area using a single surface Subsonus unit, each tag is uniquely addressable and can be assigned a name for easy identification.

Integrated Display

Featuring a pressure-tolerant display, the Subsonus Tag allows for the quick and easy identification of multiple tags and their statuses. Its use of electronic paper technology ensures that no power is consumed between screen graphic updates.

Hermetically Sealed

Subsonus Tag’s innovative design encapsulates the electronics and batteries, creating a hermetic seal that offers unparalleled reliability. This seal eliminates the need for pressure vessels, air cavities, O-rings or connectors. The only servicing required is biofouling management.

Wireless Charging

Equipped with a Qi-compatible wireless power receiver, the Subsonus Tag offers convenient battery charging without using connectors. Qi charging is found in most smartphones, so chargers are readily available and affordable.

Bluetooth Communication

Subsonus Tags can be quickly configured and updated from a smartphone using Bluetooth. Additionally, an RS232 or USB Bluetooth interface is also available for PC-based configuration.

Breakthrough Price

The Subsonus Tag sets a new standard for affordability in the underwater transponder market, thanks to its hermetically sealed, connectorless design. This lowered cost allows it to be used in a wide variety of applications previously limited by budget constraints.

1000 Metre range

The Subsonus Tag has an acoustic tracking range of up to 1000 metres and is depth-rated to 2000 metres, offering extensive operational flexibility.
