The Marine Hydrographic and Oceanographic Service (Shom) wanted to equip its boats with a rapid survey kit to carry out bathymetric reconnaissance surveys on partially surveyed areas, especially overseas (Nouméa, Papeete, etc.).
The Shom expresses the need to acquire several data acquisition systems for recgnition to support in situ decision-making. These systems are intended to be operated by non-hydrographer personnel (mainly deck personnel on boats), without prior training, from inflatable boats.
In 2020, through a public procurement, the Shom chose Cadden to supply these lightweight hydrographic systems. The equipment proposed by Cadden is a version of the autonomous bathymetry system BALI adapted to the constraints of the Shom.
The BALI Hydrographic System is a bathymetric measurement system recognized for its ease of use and implementation of bathymetric reconnaissance surveys. The BALI Lightweight Bathymetry Kit is waterproof and robust, meeting the extreme conditions required by the Shom.
Thanks to the integrated and intuitive web server, the acquisition is simple and ergonomic with optimized data processing. Energy-independent, it incorporates a power box including a NiMH battery with 10 hours of battery life.
BALI meets the expectations of the Shom since users are satisfied with the lightweight hydrographic system provided; both by the simplicity of the acquisition, managed as a touch screen application, that in the optimization of the processing where interoperability with the SENIN* system, equipping the carriers of the National Navy, is a real asset.
*SENIN is a navigation aid system that uses digital mapping to enhance navigation safety. AML is referred to as “Additional Military Layer” in the case of overlapping layers of complementary information (e.g., meteorology, or others from embedded operational information systems).
