SeaTrac Positioning & Navigation
SeaTrac is a USBL acoustic positioning system
Compact form meets robust function. SeaTrac is a high accuracy USBL acoustic positioning system for real-time ROV, AUV and diver tracking. With a 1000m range and the ability to both track and exchange data with multiple assets, the list of potential applications is endless.
Don’t worry about sounding professional. Sound like you. There are over 1.5 billion websites out there, but your story is what’s going to separate this one from the rest. If you read the words back and don’t hear your own voice in your head, that’s a good sign you still have more work to do.

SeaTrac Range
SeaTrac Standard
The SeaTrac Standard system contains both an X150 USBL beacon and an X110 transponder beacon, everything required to track the position of ROVs and AUVs in real-time down to a depth of 2000m.
Simple, robust position tracking system for deeper water applications
AHRS and Active Doppler Compensation equipped beacons for reliable and accurate location data
Stainless steel housings promote longevity on larger inspection class ROV installations
Intuitive SeaTrac PinPoint software interrogates up to 14 beacons for real-time relative and actual positional data
Accepts an external heading input and outputs a NMEA string for use in other devices
X110 beacon can be powered from a battery for standalone diver tracking
OEM systems and software SDKs available for integrators and developers
SeaTrac Lightweight
The SeaTrac Lightweight system contains both an X150 USBL beacon and an X010 transponder beacon, ideally suited to tracking ROVs and AUVs in real-time down to a depth of 300m.
