Cellula Robotics Selects Sonardyne for Long-Range AUVs
Autonomous subsea robotic systems developer Cellula Robotics has chosen Sonardyne navigation and positioning technology for its long-range autonomous underwater vehicle (AUV) platforms.The company has ordered multiple Sonardyne SPRINT-Nav X navigation systems - Sonardyne's highest grade and underwater navigation system.The company has also selected Sonardyne’s AvTrak 6 for tracking, communications and mission control. Part of the package/purchase is multiple Sonardyne Ranger 2 Ultra-Short BaseLine (USBL) positioning and communications systems for both AUV end users and demonstration and
Exail Supplies LBL Positioning Systems for Deepwater Projects in Brazil and Angola
, supporting subsea construction, offshore infrastructure installation, and survey operations in complex environments at depths of up to 4,000 meters.In Brazil, for a major ultra-deepwater gas development, Exail is supplying a network of 56 Canopus acoustic transponders paired with Rovins inertial navigation systems (INS). This installation establishes the primary subsea positioning reference required for the field’s critical construction phases. In Angola, on a mature offshore oil field, Exail’s technology is supporting the expansion of existing subsea infrastructure. By interfacing Ramses
Ashtead Technology Places New Order for Sonardyne’s Fusion 2 Platform
and wireless structure deflection monitoring.These features significantly reduce transponder count, vessel time and operational costs while ensuring centimetric accuracy in subsea positioning.As well as Compatt 6+ and ROVNav 6+ Ashtead Technology’s expanded fleet now includes SPRINT-Nav navigation systems, Nano transponders and RT 6 acoustic releases.Together, these technologies form the most capable and compatible subsea positioning and navigation solutions available in their fleet. "Fusion 2 represents five decades of pioneering innovation at Sonardyne, driven by our goal to make
Automatic docking as an enabling technology for the operational autonomy of underwater systems
in the overall duration of data acquisition campaigns.The evolution of docking technology has followed a gradual path: from early manual or assisted solutions, which required significant operator support, to more recent implementations of automatic docking. The latter are based on precision navigation systems, acoustic and optical proximity sensors, advanced control algorithms and autonomous decision-making logics, capable of robustly managing the approach, capture and disconnection phases even under challenging environmental conditions.Automatic docking does not represent a mere incremental improvement
Greensea IQ Introduces Bayonet Insight Post-Mission Analysis Toolset
maritime robotics software products deployed to defense forces. Bayonet Insight supports all software deployed on Bayonet Autonomous Underwater Ground Vehicles (AUGVs), EOD Edge and EOD Workspace deployed on Mission Specialist Defender ROVs by VideoRay (an AeroVironment company), RNAV diver navigation systems by STIDD Systems, Bayonet Underwater Control (BUC) systems, and Greensea’s EverClean ship maintenance and inspection robots. The tool was developed in response to a persistent need from operators for faster access to mission insight.Bayonet Insight enables operators to process raw mission

its day). He compared the time from a known location – such as where the ship set sail from – with the time of day where the ship was located. Knowing the difference in time of when noon occurred allowed the ship to precisely know its longitudinal position.”By the 1980s, satellite navigation systems in the Global Navigation Satellite System (including GPS) rendered chronometers largely obsolete for practical navigation, because the time signals needed for accurate navigation mostly then came from atomic clocks on GNSS satellites.If GNSS is disrupted, atomic clocks provide reliable holdover
