1. ROV Tracking And Navigation 

TrackLink systems have been used to track numerous ROVs including those from Deep Ocean Engineering, Hytec, Nova Ray, SeaBotix, Seaeye, Sub-Atlantic, VideoRay and Benthos all over the world. The Broadband Acoustic Spread Spectrum technology has set a new higher standard for robust and accurate ROV tracking and navigation. Extra telemetry option provides an easy way to add more data channels other than through the ROV umbilical.  Highly reliable acoustic link can be used to command the ROV in case the umbilical is cut.

2. AUV/UUV Tracking And Communication

The acoustic tracking system and the high speed acoustic modem share the same electronics stack and the transducer.  This approach eliminates the acoustic interference that typically exists between the acoustic tracking and communications systems.  The size and weight of the overall system are also significantly reduced.

4. Diver Navigation And Tracking  

Track multiple divers simultaneously.  Each diver obtains his/her owner GPS position with assistance of the acoustic link.  Each diver can also send sensor information and images to the surface support vessel. 

5. Survey Towfish Tracking
