SPH Engineering delivers a fully integrated ecosystem for water depth and hydrological surveys—far beyond a simple echo sounder. The package combines the Echo Sounder with the SkyHub onboard computer, radar altimeter for precise altitude control, UgCS flight planning software, and Hydromagic Survey or BeamworX software for data processing and analysis. Supported by expert training, this all-in-one solution equips clients with everything needed to plan missions, collect accurate bathymetric data, process results, and transform them into actionable insights.
Instead of sourcing and integrating components separately, customers receive a turnkey system designed, tested, and supported by SPH Engineering to ensure efficiency, reliability, and confidence in every survey.
Compatible drones: DJI M400/M350/M300, Inspired Flight IF1200A, Inspired Flight IF800, Harris Aerial H6, and Wispr Ranger Pro and similar UAV
