Fast and effective customer service
Over time, the team at GeoSurveys have managed to harness the full spectrum of features and benefits of the Sonic 2020-V. As a result of the compact, lightweight design, balanced with its versatility, and data quality, GeoSurveys has been able to optimize both the collection and processing workflows to deliver high quality results on a day-to-day basis. Decreased time on survey and post processing ensures the quickest product delivery and cost reduction, which is passed on to their customers. "When we combine our Sonic MBES + TruePix + Backscatter + LIDAR + SBP + Mag everything matches when the data is loaded, without the need for any extra processing, commonly creating billions of very accurate sampled points"
Recent survey results example:
- Water depth of up to 15m, with an overall error of 1.45cm/m2 and 99.75% of the soundings exceeding IHO Exclusive Order (on patch test calibration and RAW data). - Only 2 hours of time taken to fully process the data from 3 survey days, including TruePix and Backscatter. - Pre-processing with just PPK and SVP. For processing, they just imported the data, PPK trajectory, SVP, and proceeded with automatic and “residual “ manual filtering. - 1,38% of data was the final removed noise. - Span and 95% confidence level achieved <5cm deviance

"Proud owners of Sonic 2020-V systems since 2021, we love how easy it is to set up the systems on virtually any vessel, and how easily we can achieve either IHO Exclusive Order or Special-Order quality surveys. In fact, we often exceed these expectations"
