The EchoNIMBUS-SSS is SPH Engineering's drone-integrated dual-channel side-scan sonar payload — built for high-resolution acoustic imaging of the seabed and water column in shallow, hazardous, or vessel-inaccessible environments. Deploying two Cerulean Omniscan 450SS transducers from a foldable UAV-mounted arm, it delivers wide-swath bottom imagery for object detection, habitat mapping, and underwater infrastructure inspection with the speed and safety of drone operations.

Dual-Channel Sonar. Wide-Swath Clarity.
Two Cerulean Omniscan 450SS transducers operate simultaneously at 450 kHz, delivering dual-channel side-scan imagery across a wide lateral swath from a single drone pass. The integrated Ethernet switch module manages both sonar data streams and SkyHub connectivity in a unified network — enabling real-time georeferenced acquisition via UgCS Expert with no manual data stitching required. The result: high-resolution acoustic bottom imagery at survey-grade quality, without a vessel.

Foldable Mount. Deploy in Seconds. The integrated foldable arm and electronics housing stow compactly for transport and deploy instantly at the water surface — protecting transducers and UAV while maintaining the low, stable altitude required for optimal side-scan resolution.

UgCS-Native Mission Control. Plan, execute, and log side-scan surveys with full UgCS Expert integration — including True Terrain Following, automated flight lines, and real-time depth monitoring. From mission brief to georeferenced deliverable, the workflow is seamless.

Survey-Ready in Any Environment. From flooded infrastructure to remote river systems, the EchoNIMBUS-SSS operates where boats cannot — delivering wide-swath acoustic imagery for object detection, habitat classification, and environmental baseline surveys with zero vessel logistics.

System Components

  • 2× Cerulean Omniscan 450SS Side-Scan Sonar — Dual-channel, 450 kHz transducers delivering high-resolution acoustic imagery across a wide lateral swath
  • Foldable Mount & Electronics Housing — Compact stow for transport; deploys at the water surface for stable, low-altitude sonar acquisition
  • Ethernet Switch Module — Manages dual-sonar data streams and SkyHub connectivity in a single integrated network
  • Explorer Transport Case — Rugged hard case for safe field transport of all system components

Capabilities

  • Dual-channel side-scan imaging for wide-swath bottom coverage with minimal flight lines
  • High-resolution acoustic imagery for object detection, debris mapping, and habitat classification
  • Compatible with SkyHub onboard computer and UgCS Expert for automated mission planning and real-time data acquisition
  • Georeferenced data output compatible with standard GIS and hydrographic processing workflows

Applications

  • Seabed and riverbed mapping in shallow, hazardous, or vessel-inaccessible waters
  • Submerged object and debris detection
  • Underwater infrastructure inspection (pipelines, cables, bridge footings)
  • Habitat and environmental baseline surveys
  • Flood mapping and post-event assessment
  • Mining and industrial basin monitoring

Operational Notes

  • Optimized for calm to moderately flowing water; zig-zag flight patterns recommended in faster currents
  • Requires compatible UAV platform (DJI M300/M350 RTK or equivalent) and UgCS software/licenses for full integration
