Efficient surveying in areas where boats cannot operate with drone-based bathymetry.
We offer open-source APIs for our devices, empowering developers by simplifying integration, accelerating development, improving functionality, and enhancing compatibility. This strategic move not only boosts developer satisfaction and productivity but also strengthens our market position and drives innovation.
Echologger APIs
Drone-based bathymetry enables efficient surveying in areas where boats cannot operate - shallow channels, wetlands, steep banks, vegetation-obstructed zones and restricted-access sites. Echologger’s drone-ready towable echosounders are engineered for stable airborne towing, low-drag behaviour and reliable acoustic performance during low-altitude flights.
The towable versions include additional integrated weight compared to standard units, improving cable tension and ensuring stable orientation when towed by drones. Hydrodynamic housings, durable construction and gland-sealed cable entry make these sensors suitable for repeated UAV missions.
Typical UAV-based bathymetry applications are demonstrated by our esteemed partner, SPH Engineering, on their website:
