Its all-in-one design tightly couples Sonardyne's SPRINT iner- tial and Syrinx Doppler technolo- gies to enable marine robotic plat- forms to remain precisely on course over many kilometers traveled, even if one or two DVL beams become unavailable. iXblue INS, USBL Chosen For Titanic Expedition OceanGate Inc. and iXblue are combining forces to conduct the first manned submersible expedi- tion to the wreck of the RMS Titan- ic since 2005. iXblue's Phins 6000 inertial navigation system and Po- sidonia USBL positioning system will be used for the accurate and reliable navigation and positioning of OceanGate's Titan, the newest addition to the company's fleet of deep-sea manned submersibles and the first privately owned manned submersible capable of reaching Ti- tanic depths. iXblue's strap-down fiber-optic gyroscope (FOG) technology, Phins 6000 subsea inertial navigation sys- tem (INS), provides accurate posi- tion, heading, attitude, speed and depth information as the manned submersible captures laser data and the first-ever 4K images of the RMS Titanic shipwreck and debris fields. Its high-accuracy inertial measure- ment unit is coupled with an em- bedded digital signal processor that runs an advanced Kalman filter for optimum positioning of the subsea vehicle. Increased positioning precision of Titan on the shipwreck site will be provided by Posidonia, iXblue's long-range, high-accuracy USBL system operated from the surface ship and calibrated thanks to a Phins surface INS. Designed to track subsea vehicles to depths of 6,000 m at ranges reaching more than 10,000 m, Posidonia uses advanced acoustic modulation and digital signal processing technology and operates in the low frequency band for deep-sea tracking operations. To communicate with Posidonia, Titan is equipped with iXblue's MT8 com- pact low-frequency transponder. AI Development for Oil, Gas E&P Total and Google Cloud have signed an agreement to jointly de- velop artificial intelligence (AI) solutions applied to subsurface data analysis for oil and gas exploration and production (E&P). The agree- ment focuses on the development of AI programs that will make it pos- sible to interpret subsurface images, notably from seismic studies (using computer vision technology), and automate the analysis of technical documents (using natural language processing technology). These pro- grams will enable Total's geologists, geophysicists, reservoir and geoin- formation engineers to explore and assess oil and gas fields faster and more effectively. Total geoscientists will work with Google Cloud's machine learning experts in the same project team. ST
