Exail Gaps M7: Pre-Calibrated High-Performance USBL System

Precision Acoustic Tracking and Communication from Shallow Water to 7,000m

Product Overview The Exail Gaps M7 (formerly iXblue Gaps) is the flagship of the Gaps Series, renowned for its "all-in-one" design that integrates a high-performance Fiber-Optic Gyroscope (FOG) Inertial Navigation System (INS) with a unique 3D acoustic array. This integration eliminates the need for time-consuming on-site USBL calibrations, allowing for "plug-and-play" deployment within minutes.

Designed for the most demanding subsea missions, the Gaps M7 offers a unique 200° acoustic aperture, enabling true horizontal tracking without the need to tilt the antenna. This makes it the premier choice for tracking multiple ROVs, AUVs, and towfish in extremely shallow waters, high-noise environments, and ultra-deepwater operations down to 7,000 meters.

Why Choose the Exail Gaps M7?

• True Calibration-Free Operation: Because the USBL antenna and the INS (Phins-based) are factory-calibrated in a single rigid housing, there is no need to perform "box-ins" or sensor alignment in the field.
• Exceptional Horizontal Tracking: The patented 3D 4-hydrophone antenna design provides omnidirectional coverage. It can track assets even when they are above the horizontal plane of the transceiver, a feat impossible for standard 2D USBL systems.
• Deep-to-Shallow Versatility: Equally effective in 10m of noisy harbor water as it is at 7,000m in the open ocean. It is the only system that truly masters the "shallow-water horizontal" challenge.
• Positioning & Communication: Much more than a tracking tool, Gaps M7 features a robust acoustic modem for commanding AUVs, retrieving sensor data, and re-aligning subsea INS systems.
• Third-Party Friendly: Open architecture ensures compatibility with iXblue transponders (MT9, Canopus) as well as third-party beacons, allowing for easy integration into existing equipment pools.
