The APEKS ABATH-3 is a highly-integrated, lightweight and portable autonomous single-beam survey vessel. It integrates high-precision dual-antenna GNSS, IMU and depth sounder onboard.
RAPID DEPLOYMENT
Boasting a streamlined, ready-to-use design, it can be deployed by one operator within minutes.
AUTONOMOUS SURVEYING
Suitable for lakes, inland rivers and coastal waters, the ABATH-3 runs along pre-programmed routes autonomously. It automatically collects, processes and analyzes underwater terrain and water-quality data.
ALL-WEATHER PRECISION
With centimeter-level positioning and all-weather performance, it elevates the efficiency and coverage of shallow-water survey operations.
Lightweight Hull,
Easy Deployment
The 7 kg carbon-Kevlar hull is under 1 m and fits a car trunk. No assembly needed - one person handles transport, launch and recovery.
GNSS+IMU Positioning,
Reliable Navigation
Dual GNSS + 200 Hz IMU deliver ±8/+15 mm RTK and ±0.1 heading.If signals drop,the IMU keeps position streaming so data stays continuous.
mmWave Radar,
360° Safety Monitoring
mmWave radar scans 0.1-20 m (+120°) with live alerts, plus a 360° night camera. Auto-return, full bumper and dual-redundant design add layered safety.
Single-Beam Echo Sounder,
Modular Payload
Hot-swap 33.6 V packs give 7 h@1.5 m/s or 3 h@2 m/s (top7 m/s). The bay carries a single-beam echo sounder for depth and cross-sections,plus sonar, probes, samplers, SDK support.
AquaSurvey
Intelligent USV Control & Survey Software
AquaSurvey is an integrated survey software suite for ABATH-3's controller, combining project planning,navigation, real-time monitoring,data synchronization, and secure data processing,with one-touch operation and automatic navigation.
