Doppler Velocity Log. GPS-Independent Positioning. Precise Station-Keeping. The CHASING X Waterlinked DVL A50. The CHASING X Waterlinked DVL A50 is a compact, high-precision Doppler Velocity Log (DVL) payload engineered for the CHASING X ROV, delivering accurate underwater positioning and navigation in GPS-denied environments where surface-based positioning systems cannot reach. By measuring the ROV's velocity relative to the seafloor using acoustic Doppler technology, the DVL A50 enables precise station-keeping, repeatable survey transects, and confident navigation through complex underwater structures — capabilities that are essential for professional infrastructure inspection, scientific survey, and public safety operations at depth. Includes the DVL unit, mounting bracket, and complete mounting kit for direct integration with the CHASING X platform. Included in the CHASING X Advanced and Professional Sets, or available as a standalone payload for Standard Set operators. Key Features Doppler Velocity Log (DVL) Technology — Measures ROV velocity relative to the seafloor using acoustic Doppler sensing for accurate, drift-free underwater positioning without GPS GPS-Independent Positioning — Enables precise navigation, station-keeping, and positioning in GPS-denied and zero-visibility underwater environments Precise Station-Keeping — Holds the CHASING X in a fixed position relative to the seafloor for detailed inspection passes, close-range imaging, and sensor data collection Repeatable Survey Transects — Accurate velocity data enables consistent, repeatable survey paths for infrastructure monitoring, photogrammetry, and scientific data collection Complete Mounting Kit Included — DVL unit, mounting bracket, and mounting kit included for direct integration with the CHASING X ROV platform CHASING X Compatible — Included in the Advanced and Professional Sets; available as a standalone upgrade for Standard Set operators Specifications Sensor Type Doppler Velocity Log (DVL) Positioning GPS-independent, acoustic Doppler Compatible ROV CHASING X SKU 843722102627 Weight 5 lbs Country of Origin China Vendor CHASING / Waterlinked In the Box Waterlinked DVL A50 × 1 DVL Mounting Bracket × 1 DVL Mounting Kit × 1
