Overview
Doppler Velocity Log. GPS-Independent Positioning. Station-Keeping. Repeatable Survey Transects. CHASING X Compatible.
Professional ROV operations in GPS-denied environments demand a positioning solution that doesn't rely on surface signals. The CHASING X Waterlinked DVL A50 delivers exactly that. Using acoustic Doppler technology, it measures the CHASING X's velocity relative to the seafloor with high precision — enabling accurate, drift-free positioning without GPS in zero-visibility, deep-water, and structurally complex underwater environments. Precise station-keeping holds the ROV in a fixed position relative to the seafloor for detailed inspection passes, close-range imaging, and sensor data collection that requires the ROV to remain stationary. Accurate velocity data enables consistent, repeatable survey transects for infrastructure monitoring, photogrammetry, and scientific data collection where path consistency directly impacts data quality. 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 upgrade for Standard Set operators.

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.
