NemoSens µAUV
A compact, lightweight micro-class autonomous underwater vehicle built on an open Linux-based architecture. Supports ROS and MOOS-IVP interfaces so operators can develop and load custom mission algorithms. Designed for scientists and offshore engineers who need a flexible, affordable platform for research and specialised underwater surveys, with modular payload integration including CTD probes.
COMET-300 AUV
A man-portable autonomous underwater vehicle rated to 300 metres depth, designed for long-range survey missions. Used for bathymetry, seabed surveys and unexploded ordnance detection. A dedicated mine countermeasures configuration, COMET-MCM, equips the vehicle with acoustic sensors for unmanned detection and classification of underwater mines.
SonaDive
A handheld sonar system carried by EOD divers during mine countermeasures operations. Allows underwater personnel to detect, locate and identify mines and unexploded ordnance in manned diving scenarios, forming the diver-held element of RTsys's broader MCM ecosystem alongside AUVs and acoustic beacons.
SEMA ASW Training Target
An acoustic training target used by navies for anti-submarine warfare exercises. Allows naval crews to conduct torpedo firing exercises and acoustic systems tests against a realistic underwater target. Used by the French Navy and Dutch Royal Navy for training and crew certification.
SIERA Sonar Measurement System
An acoustic signature measurement system used to characterise the acoustic signature of surface vessels and submarines. Supports navies in conducting acoustic systems tests, calibrating sonar equipment and benchmarking vessel signatures for stealth assessments.
SYSENSE Seabed Station
A seabed-mounted observatory for passive acoustic monitoring combining acoustic recording with measurements of salinity, water depth and turbidity. Supports real-time monitoring and remote control, suited to long-term multiparameter studies for environmental research and offshore industry noise impact assessment.
