Gaps Series USBL
High-accuracy USBL acoustic positioning and communication systems with embedded gyroscope and motion sensors.
Description
The Gaps Series are ultra-short baseline (USBL) acoustic positioning and communication systems from Exail, models Gaps M5 and Gaps M7. They track divers, work-class ROVs and AUVs and support dynamic positioning operations, with built-in gyro and motion sensors that make the M5 and M7 calibration-free.
Key features
- 3D omnidirectional acoustic antenna with a 200 degree aperture for true horizontal tracking without tilting the antenna
- Operation from ultra-shallow waters to 7,000 m depth
- Acoustic telemetry, including messages to multiple UUVs and INS re-alignment
- Open architecture compatible with third-party transponders
- Web-based MMI
Applications
Diver tracking, work-class ROV surveys, AUV missions and dynamic positioning operations.
