High‑Performance Velocity Logging for ROV Integration
The Tracker 650 Doppler Velocity Log (DVL) is purpose‑built to deliver exactly what modern ROVs require: precise velocity data for reliable station keeping, position hold, and advanced navigation control.
By focusing purely on velocity measurement, the Tracker 650 avoids unnecessary complexity and cost. Instead of incorporating an internal attitude sensor, it intelligently relies on the vehicle’s existing IMU as the primary reference for orientation. This streamlined approach reduces system redundancy, minimizes calibration effort, and simplifies overall integration.
Designed for OEMs and Professional ROV Platforms
The Tracker 650 is an excellent choice for ROV manufacturers and system integrators looking for a compact, efficient, and dependable DVL solution. It integrates seamlessly into new or existing underwater vehicle platforms and supports advanced stabilization and tracking algorithms within the vehicle’s control system.
Cerulean provides comprehensive technical documentation and engineering support, ensuring smooth OEM integration from prototype to production.
Key Benefits
Accurate velocity data for underwater navigation
Optimized for position hold and tracking applications
No built‑in IMU – reduced complexity and calibration time
Ideal for OEM and professional ROV integration
Backed by full engineering and documentation support

Cost‑Effective Doppler Velocity Log for Small ROVs
The Tracker 650 is a compact and affordable Doppler Velocity Log (DVL) designed to deliver exactly what most ROVs need: accurate velocity data for stable and precise underwater control. By focusing on core functionality and eliminating unnecessary complexity, Tracker 650 offers reliable performance at a highly competitive price point.
Instead of integrating its own IMU, the Tracker 650 uses the vehicle’s existing IMU as the reference for attitude. This reduces system complexity, lowers cost, and makes installation and calibration significantly easier—only one IMU needs to be configured.
Ideal for OEMs and ROV manufacturers, the Tracker 650 is supplied with complete documentation and engineering support to ensure smooth integration into custom platforms.
Why Add a DVL to Your ROV?
✅ Position Hold
Maintain a fixed position underwater with confidence. The Tracker 650 enables advanced stabilization features such as position hold, eliminating drift caused by currents or tether movement. Fully compatible out of the box with BlueOS, ArduSub, and MAVLink systems.
✅ Position Tracking
The Tracker 650 continuously sends position delta data to ArduSub via MAVLink REST. When a global origin is set, your ROV’s position can be visualized directly in QGroundControl, giving operators clear spatial awareness during missions.
✅ Live Sonar Mosaic Imaging
When paired with imaging sonars like the Omniscan 450FS or Ping 360, the Tracker 650 enables real‑time sonar mosaic generation using Cerulean’s SonarView software. This delivers situational awareness comparable to high‑end multibeam systems—at a fraction of the cost.

The Omnitrack Underwater Positioning System is a modern, high‑precision solution for tracking and positioning underwater vehicles and assets. Designed for professional marine operations, Omnitrack combines advanced surface positioning technology with seamless ROV integration to deliver reliable and repeatable underwater navigation.
Advanced Surface Positioning with GNSS Heading
At the heart of the system is a rugged surface positioning buoy, engineered to operate as a stable reference point on the water. Equipped with dual GNSS receivers, the surface module provides highly accurate global positioning while simultaneously calculating true heading. This dual‑GNSS design removes common errors caused by magnetic interference, ensuring dependable orientation in challenging environments.
Accurate Underwater Target Tracking
The surface unit works in conjunction with an integrated acoustic locator to precisely track underwater targets. This makes Omnitrack ideal for:
ROV navigation and survey missions
Inspection and mapping tasks
Scientific research and offshore operations
Optimized for BlueROV Integration
Omnitrack is designed to interface directly with BlueROV systems, significantly improving the vehicle’s internal position estimation. For enhanced performance, the system can also be paired with a Tracker‑650 DVL, enabling smoother navigation and higher accuracy during complex underwater maneuvers.
Flexible Deployment Options
To suit different operational needs, the surface module is available in both:
Wired configurations for maximum stability
Wireless configurations for rapid deployment and operational flexibility
Key Benefits
High‑accuracy GNSS‑based surface positioning
True heading without magnetic interference
Improved ROV navigation and situational awareness
