as a versatile vehicle that easily pairs with a variety of accessories. This particular model will be equipped with a handheld pendant controller, and a fiber optic tether multiplexer upgrade. These will help control a wide array of on-board instrumentation such as USBL underwater positioning system with GPS integration, the ROV to be tracked in real-world coordinates in real time, and an integrated Tritech Micron Echosounder which permits the ROV to measure its height above the seafloor and maintain its height with our auto-altitude system. This vehicle will also come with a dual function gripper, a

the planet’s sea floorsMany unknown landscapes in our planet are under oceanic waters. Nowadays, sea floors and polar regions build up two big frontiers for research in the field of Earth Sciences. In this context, the application of advanced technologies in scientific campaigns – differential GPS, high resolution multibeam bathymetry, 2D and 3D reflection seismic imaging, remotely operated underwater vehicle (ROV) – was a methodological revolution that broadened the precision of bathymetry maps in sea floors.The INBIS channel is located in the northern western side of the Barents Sea

The IPS system, which is moving from the leisure boat market to commercial vessels, gives the operator fine motor control of the boat for delicate maneuvers.The boat also has Volvo Penta’s Dynamic Positioning function, which utilizes the ship’s GPS coordinates to hold the vessel’s position and heading like an invisible anchor. The ability to hold the ship’s position is critical for researchers to take the time needed to gather data for their research.The fast coastal research vessel has a range of 500 nautical miles, a cruising speed

that same year, following the gas discovery of 1965. “I and others were helping to map the sea bottom for rigs and pipelines, while, in the background, providing equipment for defence and ship building, etc.,” says Klein.The development of electronic and a new global positioning system (GPS) would spur them on.  Indeed, the advent GPS revolutionized navigation. While rudimentary at the time, compared with to, it was an eye-opener for those who got to try it out. “I recall our first sat-nav system, with black punch tape that fed out of one machine to be hand fed into the next

of consumer electronics, it is very rapid product development. The AUV community is moving quickly into the next 25 years.ASVs ThenAs with AUVs, MIT was a source of early autonomous surface vehicle (ASV) development. There were significant parallels with AUV work. Early prototypes in the 1990s did not use GPS, lacked WiFi, and struggled with payloads. Like the Odyssey AUVs these vehicles used a fully autonomous approach without any vehicle interaction once a mission was launched. One area of early innovation on the surface was the use of internal combustion engines for propulsion. These early ASVs were

and pollutants such as plastic.With a requirement to track large quantities of drifters, SPOT Trace’s low device cost and affordable data charges were key factors in NATO’s procurement decision. Buoys are fitted with a small (7x5 cm) SPOT Trace device which includes an integrated GPS receiver, simplex transponder and motion sensor.NATO STO CMRE is conducting several studies in parallel. One, sponsored by the U.S. Office of Naval Research, is using SPOT Trace-equipped drifters to conduct oceanographic studies in the Alboran Sea in the Mediterranean, between the Iberian Peninsula

Sea Level Variation Study Using GPS and an Ice Profiling Sonar

Dr. David Holland of New York University, in collaboration with Dr. Natalya Gomez at McGill University, is leading an investigation of sea level variations in the Disko Bay region of western Greenland.  A shore-based system compares the direct arrival of GPS signals to the signals reflected off the sea surface to obtain sea level. The presence of sea ice and icebergs complicate the measurements. A shore-mounted camera provides information about the surroundings and the presence of sea ice and icebergs when there is daylight.  Underwater sonar devices can supplement the camera-based

navigational accuracy by integrating low- and high-power Inertial Navigation System (INS) sensors.  Geraint West, Global Business Manager - Oceanographic, Sonardyne said, "The accuracy of low-power sensors degrades over time and AUVs consequently often have to surface to reinitialise with a GPS fix. However, by including high-performance, high-power navigation instruments, like our SPRINT INS, and integrating them with the low-power instruments to dramatically reduce power consumption, vehicle operators will get the best of both worlds, which will enable longer-duration independent deployments

gas environment that can cause major delays in projects and impact vessel, operational and crew safety.The new antenna from VERIPOS, part of Hexagon’s Positioning Intelligence division, works to nullify the interference or jamming source that’s trying to overpower the satellite signals that GPS positioning systems use to determine location. With the source nullified, the receiver can acquire and track GPS signals while maintaining high-accuracy positioning.The technology that the VERIPOS GAJT 710-MS uses has been battle-tested and proven to work in some of the most demanding environments

Mapping the Future

the surface, how challenging is it to ensure controlled, safe navigation of both vessels during mapping operations?The system architecture of autonomy for planning, analysis and execution is similar for AUVs and USVs but there are differences in sensors and functions because of the environment. Lack of GPS and radio communication are fundamental constraints to AUVs that are solved by acoustics and aided inertial navigation systems.USVs need advanced scene analysis and route planning to navigate safely in areas with maritime activity. There are significant thresholds to sufficient functionality and robustness
