The Argus, our advanced UAS survey boat, delivers vastly improved data accuracy by executing fully autonomous missions guided by precise, pre-programmed GPS paths. Operating seamlessly in sensitive riparian zones, it navigates shallow shorelines, narrow channels, and hazardous areas that traditional, manned vessels simply cannot reach. By removing human steering variance, the Argus ensures perfectly spaced, consistent survey lines that eliminate gaps and cover the entire site with mathematical precision, all while keeping a minimal footprint that protects fragile habitats.
 

​Once on the water, the Argus provides a massive leap forward in data quality compared to traditional manual stick silt measurements, which rely on a handful of physical prods and rough averages to guess the underwater terrain. Instead, the Argus utilizes specialized dual-frequency echo sounders to scan the environment, capturing thousands of continuous data points to map the true bed topography. By sending sound waves through the water, it penetrates soft organic silt to clearly differentiate between loose sediment and the hard bottom beneath. This dense, comprehensive data eliminates guesswork, allowing project managers to calculate exact sediment volumes and establish a flawless pre-dredge baseline.
