Argeo Buys Two SeaRaptor AUVs
with the latest Kraken MinSAS 120 Synthetic Aperture Sonar (Kraken Robotics, Canada) providing large swath area coverage and high-resolution imagery and bathymetry data collection. The vehicles will also be fitted with Teledyne RESON T50-S Multi-Beam dual frequency 200/400 kHz Echo Sounders, Teledyne Benthos Chirp III Sub Bottom Profilers, iXblue PHINS 6000 INSs coupled to Teledyne RDI Tasman DVLs, and CathX Hunter Camera Systems. All data collected will be processed onboard using Teledyne CARIS OnBoard postprocessing and mosaicking software to allow quick turnaround during missions. The AUVs are
Teledyne Marine Introduces New Ultra Compact Acoustic Modem
Teledyne Marine announced the launch of its new Ultra Compact Modem (UCM). At 60 by 50 millimeters, and weighing 55 grams, the OEM version of the UCM is the smallest acoustic modem ever designed by Teledyne Benthos.The UCM is based on Teledyne Benthos’ signal processing technology to address the need for reliable wireless underwater acoustic communications onboard the growing number of autonomous micro vehicles and other subsea instruments. As the size of these micro vehicles continues to decrease, Teledyne Marine has responded with lightweight, low power, proven sensors and systems to expand
Greensea Hires Keefer as Senior Robotics Engineer
to Greensea from Raytheon where he was Deputy of Undersea Machine Learning IRAD. He has a bachelor’s degree from University of Rhode Island in Physics and Physical Oceanography and over a decade of experience building and deploying autonomous systems including several years at Hydroid and Teledyne Benthos.Shay Osler, Chief Engineer, said he is pleased to be expanding the engineering team with such an experienced unmanned underwater systems engineer. “Andrew has already proven to be a strong contributor to our team. His skills are being utilized on several of Greensea’s newly awarded
Teledyne Benthos Acoustic Modems Aid in Innovasea Fish Tracking
used for tracking and recording tagged fish populations. The VR4 is a submersible receiver capable of identifying all Innovasea coded transmitters and communicating that data remotely to a surface modem on demand. The subsea acoustic communications are conducted via a fully integrated OEM version of Teledyne Benthos CM-903 Compact Modem. Teledyne says its acoustic modems are suited for this application due to their robust communication schemes, low power consumption, and proven dependability in a wide array of challenging environments.“Our advanced VR4 Underwater Modem receiver is an extraordinary

sea acceptance testing of the SeaRaptor, 6,000m rated autonomous underwater vehicle (AUV). The client was not disclosed.The SeaRaptor AUV incorporates a broad range of Teledyne content including acoustic modems, ascent and descent weight releases, a black box pinger locator, sub-bottom profiler (Teledyne Benthos), multi-beam echosounders, obstacle avoidance multi-beam sonar (Teledyne RESON), Doppler Velocity Log (DVL), Current, Temperature, and Depth sensor (CTD) (Teledyne RD Instruments), and onboard processing software (Teledyne Caris). In addition, the vehicle delivered also carried an Edgetech Side
Oi: Tracking 50 Years of Ocean Innovation
had a mobile phone back then, it maybe worked in Europe, and, if it did, it was really expensive and I didn’t use it,” says Manley, who is founder at Just Innovation, and who has worked in the field of unmanned marine vehicles at Massachusetts Institute of Technology, Liquid Robotics and Teledyne Benthos. “Now, anywhere outside the U.S. my phone works.” The miniaturization and affordability of satellite data telemetry and positioning have driven advances in his world. “Crazy ideas we had in 2002, for unmanned surface craft, as we tried to call them, didn’t work then.
Teledyne Gavia: New SeaRaptor 6000m AUV
Gavia will introduce its new 6000 meter rated AUV -- SeaRaptor -- at Ocean Business 2019 in Southampton in April.SeaRaptor AUV incorporates a broad range of Teledyne content including acoustic modems, ascent and descent weight releases, a black box pinger locator, sub-bottom profiler (Teledyne Benthos), multi-beam echosounders, obstacle avoidance multi-beam sonar (Teledyne RESON), Doppler Velocity Log (DVL), Current, Temperature, and Depth sensor (CTD) (Teledyne RD Instruments), and onboard processing software (Teledyne Caris). In addition, the first vehicle delivered also carried an
