We are excited to share a customer testimonial graciously provided by our customer Anwar Quarishi of the Swiss Federal Institute of Technology, currently working on a subsea swarm AUV research project: Distributed 3D Environmental Sensing with a Team of Underwater Robots.


Alex: How did you know about our company?


Anwar: I have found information on UCNL through a contact attending the meeting on Leman-Baikal project in 2018. After that I have found similar devices on the platform geo-matching.com under DiveNET brand. For us it is much easier to buy from a US-based supplier.


Alex: What equipment do you use and what tasks do you solve with it?


Anwar: We intend to use Microlink/uWave underwater acoustic modems to transmit telemetry data from our AUVs (read more about the project is on EPFL website). We are also planning to use Commander/ZIMA USBL navigation system to perform tracking of our AUVs.


Alex: How did you choose specific equipment for your tasks?


Anwar: We had many conversations with both DiveNET and UCNL engineers. They proposed a wide list of options, and by iterating we came to the most efficient way to perform the tasks in our specific conditions.


Alex: What experiments have you already conducted and what results did you get?


Anwar: For now, we have performed series of tests using Microlink/uWave underwater acoustic modems in Lake Geneva or le Léman to estimate the impact of our specific conditions on the communication quality. It turns out, that communication mostly worsens in the extremely shallow water. For example, when we tried to establish the connection between two modems submerged just 20-30 centimetres, the communication range was around 20-25 meters. Of course, these are severe conditions for any underwater acoustic system, and we’ve got far better results in terms of distance when modems were submerged a little bit deeper than 1.5-2 meters. We haven’t yet run any tests to achieve maximum communication range which should be up to 1 km, but we are already planning to carry them out.


Alex: Have you used AUVs/ROVs in the course of your tests or engaged divers?


Anwar: On the current stage of our project we use a “fleet” of small surface RC boats with our AUVs.


Alex: How would you rate our tech support service?


Anwar: It surprisingly good for such a small company. We’re moving forward with our project (in terms of integrating underwater acoustic systems) pretty fast thanks to guys from DiveNET and UCNL. They are very responsible, always trying to do their best and in my opinion definitely love their job.



Beringia Enterprises LLC is excited to announce successful completion of initial deliveries of DiveNET Subsea Wireless solutions for academic subsea research projects based in Switzerland and Norway.


The Swiss Federal Institute of Technology (EPFL) has selected the DiveNET: Commander USBL positioning and navigation system, as well as the Sealink-M (Microlink) multi-mode acoustic network modem for procurement in support of the university's Distributed 3D Environmental Sensing with a Team of Underwater Robots research project, aimed at developing swarm AUV technology for environmental subsea sampling. In addition to providing multi-target subsea positioning with DiveNET: Commander USBL, the research team will utilize the Microlink acoustic modem as a building block for custom positioning and data transmission solutions.

Previously, the Microlink modem was also selected by the Oslo Metropolitan University (OsloMet) in support of the OASYS project, aimed at developing Ocean-Air synoptic operations using coordinated autonomous robotic SYStems and micro underwater gliders. Satisfied with the performance, the university has taken delivery of additional units.

It has been a great pleasure introducing DiveNET capabilities to the subsea industry over the past month at two premier conferences of the 2019 season: Underwater Intervention and Oceanology International North America. In addition to exhibiting the DiveNET product line, we are grateful for the opportunity to speak at both events and present not only our current line-up, but also a window into the future - DiveNET: Delta remote subsea IOT.


Thank you to the event organizers, all of our booth visitors and the Oceanology Future Tech Hub co-exhibitors!
