Navigation software

Known as acoustic sensors, the bathymetry, sonar imaging and sedimentology systems contribute to comprehensive mapping of the seabed and subsoil.

They are used in a wide variety of applications and at all depths during geophysical campaigns, scientific research missions and environmental or industrial monitoring.

These systems require positioning or motion compensation sensors such as a GNSS receiver and an inertial navigation system for their implementation. Others require instrumentation such as dedicated winches or underwater positioning systems for their implementation.

They are often associated with software suites for data collection, processing and analysis: QINSY, QIMERA, QASTOR, DELPH.
