The D230 is a single beam echo sounder making hydrographic surveying simpler and more productive. Advanced water depth analysis algorithm filters the secondary echo automatically and professional depth-keeping configuration ensures accurate results by eliminating noise interference. The gain, power and range are also adjusted automatically.

Tangle-Proof and Robust Motors

The Apache 3's high-efficiency DC-injected rotary motors spin up to 7,000 RPM allowing the Apache to navigate difficult weather conditions. The motors have an anti-collision design with a sealed straw cover and titanium alloy mesh for maximum durability.

Why The APACHE 3?

1.
One-Man Operation

The entire project including calibration, mission planning, and processing can be accomplished by a single person
The Apache 3 is made of a durable yet lightweight mixture of carbon fiber and Kevlar fiber-glass weighing 7 kg allowing for easy transport
With no regulations for operating an USV, the Apache is quick and easy to use on any job
4G connectivity allows RC control at all times in large bodies of water

2.
High-Accuracy

The Apache integrates highly-accuracy GNSS and IMU sensors for accurate position and attitude. These sensors compensate for hull sway.
The Apache is capable of survey-grade accuracy with the D230 Echo Sounder
Maintain high-accuracy positioning even during temporary GNSS outages while passing under bridges and structures
Tight coupling of GNSS and INS data removes outliers and increases accuracy
Use any third-party GNSS receiver or NTRIP for PPK corrections

3.
Perfectly Straight Lines

Maintain straight lines in any weather condition
High-accuracy GNSS and INS coupling allow for survey-grade bathymetric surveys completely autonomous
Keep heading at any depth and environment inclduing shoals, channels, shallow rivers, and more
