Survey the Seabed
Without Limits.
Two man-portable AUVs for oceanographic research, seabed survey, UXO detection and marine-renewable assessment. The NemoSens® micro-AUV runs 8+ hours at 4 knots on an open Linux/ROS platform; the Comet-300 fields swarms of up to ten vehicles to compress wide-area surveys from days into hours.
Two vehicles, the full survey spectrum
Crewed survey vessels are slow and expensive, and many sites — high-current tidal races, contaminated water, UXO grids — are dangerous or impossible to work by diver. RTsys answers with two man-portable AUVs that go in from a small boat and come back with the data: the NemoSens® for endurance and open-architecture development, the Comet-300 for coordinated swarm coverage.
- NemoSens® — 8+ hour micro-AUV on an open Linux/ROS platform
- Comet-300 — up to 10 vehicles in a coordinated survey swarm
- Both man-portable, modular and field-reconfigurable
The survey problems RTsys AUVs remove
Wide-area subsea survey runs into cost, coverage, access and software constraints. These vehicles were designed to break each one.
💸 Vessel Cost
Crewed survey vessels and offshore day-rates dominate budgets. A man-portable AUV from a small boat replaces much of that.
🗺️ Area vs. Time
One vehicle covering a large grid takes days. A coordinated swarm of ten covers the same area in hours.
🔒 Vendor Lock-In
Closed AUV software stalls behind vendor release cycles. An open Linux/ROS platform lets you deploy your own logic now.
🌊 Hostile Sites
High-current tidal races and contaminated water are unsafe for divers and surface craft — an AUV simply flies the mission.
NemoSens® — 8+ hours, open, modular
RTsys' flagship micro-AUV: lightweight and man-portable, with endurance that outlasts most of its class and an open architecture you can program yourself.
Endurance and openness in a one-person package
The NemoSens® is built for demanding oceanographic survey, seabed mapping, UXO detection and acoustic monitoring. Over eight hours of endurance at four knots outlasts most competing micro-AUVs, while it stays small enough for a single operator to deploy from a small vessel or shore. A modular payload bay swaps CTD, side-scan sonar, acoustic recorders and marine-mammal sensors in the field.

Linux. ROS. MOOS-IVP.
Your algorithms.
Unlike proprietary AUVs that lock you into vendor-controlled software, the NemoSens® runs a fully open Linux OS with standard ROS and MOOS-IVP interfaces. Develop and deploy your own mission algorithms, integrate custom sensors and adapt vehicle behaviour to your survey — without waiting for a manufacturer update.
- Open Linux operating system — no vendor lock-in
- ROS (Robot Operating System) compatible
- MOOS-IVP marine-autonomy mission planning
- User-programmable mission algorithms & custom sensor integration
Comet-300 — wide-area survey by swarm
When one vehicle's endurance isn't enough, the Comet-300 fields up to ten coordinated units — turning multi-day survey grids into single-shift operations.
Ten vehicles, one coordinated survey
The Comet-300 is built for wide-area seabed coverage where single-vehicle endurance falls short. Its defining capability is swarm operation — up to ten units deployed simultaneously, coordinated by a sparse Long Baseline (LBL) localisation system that feeds real-time position and navigation from the surface. UXO pre-survey grids, cable-route assessments and marine-renewable site surveys that would take days with one vehicle finish in hours with a coordinated fleet.

One AUV, multiple missions
RTsys AUVs take modular payloads across the full survey, sensing and monitoring range — swappable in the field without specialist tools.
Commercial & scientific AUV missions
Deployed across commercial, scientific and environmental survey work — replacing costly crewed vessels and reaching environments that are otherwise off-limits.
UXO Pre-Survey
Side-scan survey of cable routes, pipeline corridors and wind-farm foundations for unexploded ordnance — mandatory across many North Sea and Baltic installations.
Offshore Wind Assessment
Seabed habitat mapping, acoustic baselines and post-installation monitoring with combined CTD, sonar and acoustic payloads in one mission.
Oceanographic Research
Water-column CTD profiling, current mapping, sediment characterisation and long-distance acoustic transects for research agencies.
Seabed Mapping
High-resolution side-scan of pipeline routes, cable corridors and anchor zones for marine spatial planning and engineering.
Mobile PAM Surveys
Mobile passive-acoustic transects to assess cetacean distribution over large areas — replacing stationary arrays for density surveys.
Tidal Energy Surveys
Pre-installation seabed characterisation, current profiling and acoustic baselines where surface vessels struggle in high current.
