However, the payload is flexible and it could also work within long baseline (LBL) arrays or with a USBL system where required, with a Sonardyne AvTrak 6, providing a transducer, transceiver and telemetry link in one”, says Ward.In 2017, the company performed demonstrations and trials and the HAUV was ready for commercial operations in 2018.  In one of the trial projects in 2017, the HAUV was launched from a quayside at a lake close to Saab’s Facility in Sweden to perform a &ldquo

today is that a really good pilot could do it quicker, but not necessarily consistently and repeatedly. The technology is evolving, but I expect that auto docking and intervention operations will become faster and more consistent in the near future, providing more efficient and reliable operations.The telemetry, control systems, and communication links for ROVs have come a long way as well. Faster communication and reliable telemetry, control systems, and software advancements have enabled us to get to where we are today and will help us get to where we’re going.Does Oceaneering develop its software

discussed at the workshop was the SeaHawk from Igloo Innovations. There are two variants of this novel design, SeaHawk Alfa and SeaHawk Chimera. The Alfa looks much like a typical quadcopter and performs similarly in air.  Unlike a quadcopter, atop the Alfa is a detachable buoy containing wireless telemetry to the control station. When the vehicle submerges, the buoy remains on the surface and tethered to the vehicle thus maintaining communication.  The buoy may be removed for fully autonomous underwater operations. The Alfa has a payload capacity of 5 kg (10 lbs) and a maximum flight speed of

Its telemetry function also allows for the recalibration of the inertial navigation systems (INS) on board the underwater vehicle thanks to an acoustic communication link, as well as for the command and control of the AUV. The broad opening of its 3D antenna, up to as much as 200 degrees, also gives it unrivaled

This will have a big impact on operations such as structure installation, accelerating update rates by a factor of 10 and eliminating issues operators currently face with latency.To benefit from Wideband 3, Sonardyne has advanced its sixth-generation subsea hardware platform, with Compatt

– and high frequencies – necessary for improved resolution.”OBC vs. OBNThe fundamental difference between Ocean Bottom Cable (OBC) and Ocean Bottom Node (OBN) is that the traditional sources of technical downtime in OBC – terminations, connectors, power distribution and data telemetry – have been eliminated in designing the node to be a battery powered 4-channel flash memory autonomous seismic data recording unit. The removal of the need for power distribution and data telemetry allows for complete freedom in the spacing between receivers and the improvement in reliability

Listed as a UNESCO World Heritage site due to its diverse nature, it is an area of strict environmental conservation.MacArtney has delivered six measuring stations to a German energy supplier in May this year including six Tide Masters designed by British manufacturer Valeport, equipped with Data Telemetry Units. The Tide Master device acts as a water level recorder; it can accurately record the height of the water and record meteorological data by utilizing an ultrasonic wind speed and direction sensor. Five of the units included pressure sensors to determine the changing water levels for the purposes

modified drifting buoy. The XTP sensors are accurate to 0.005 deg. C; 10 to 20 times more accurate than temperature sensors on previous UpTempO buoys. The sensors are clamped to a jacketed wire rope tether. They communicate with the buoy through the wire rope using Soundnine’s inductively coupled telemetry.  The small size and streamlined shape of the XTP sensors should improve the survivability of the system through winter freeze-up (ice ridging) and allow this buoy to provide data throughout spring break up and the following summer
