Exail Canopus: Transponder

The Ultimate LBL Solution for Long-Term Subsea Positioning & Autonomy

Product Overview The Exail Canopus is a versatile, high-performance acoustic transponder designed specifically for Long Baseline (LBL) and Sparse-LBL positioning. As the cornerstone of Exail’s underwater acoustic range, Canopus combines advanced signal processing with extreme battery longevity to provide centimetric positioning accuracy in water depths down to 4,000 meters (with a 6,000m option).

Canopus is more than just a transponder; it is an intelligent subsea node. Equipped with hundreds of unique wideband acoustic codes, it can operate in complex, crowded subsea fields without interference. Its open architecture and integrated sensors make it the ideal choice for offshore energy construction, seafloor geodesy, and autonomous vehicle navigation.

Why Choose the Exail Canopus?

• Unrivaled Battery Life: Featuring the lowest power consumption in its class, Canopus can stay deployed for up to 140 months (Lithium) or 70 months (Alkaline) in listening mode, drastically reducing the cost of maintenance and vessel time.
• Centimetric Accuracy: Delivers range measurements with millimetric precision, enabling overall system positioning accuracy of better than 0.10 meters when used in a standard LBL array.
• Sparse-LBL Ready: Optimized to work with Exail's Ramses transceiver and Inertial Navigation Systems (INS). This "Sparse-LBL" capability allows for high-precision navigation using significantly fewer transponders on the seabed.
• Multi-User & Multi-Code: Supports hundreds of unique acoustic addresses, allowing multiple vessels and vehicles to work in the same area simultaneously (SIMOPS) without acoustic "collisions."
• Intelligent Data Logging: Beyond positioning, Canopus acts as a subsea data logger, recording internal and external sensor data to an onboard SD card.
