eSonar’s mission is to Improve access to marine and subsea environmental and geophysical data by applying advanced knowledge and translating that knowledge into actions that benefit users. Since 2009 we have pursued our mission to improve access to this marine and subsea data. Our focus is on underwater acoustic technology for the marine and subsea industries, and this includes acoustic data telemetry, acoustic release technology, Variable Buoyancy Engines and hydrophone listening arrays and multi-channel digitizers.
eSonar expertise is in advanced sonar and underwater acoustics applications to help improve the environmentally sustainable fishing, protect endangered marine mammals, save fuel, and monitor deployed gear. We use our knowledge to create products for scientists, fishing companies, defence and security users and others in the USA, Canada and internationally. We help provide real-time information on deployed equipment, endangered species such as whales in the area, and other subsea activity. We provide technology for interrogating packages on the seabed to obtain data and cause defined actions to take place. We provide micro -sonar sensors for AUV platforms that help the autonomous vehicle with real time, at-the-edge navigation, and we receive and process data from listening arrays.
Our team of sonar engineers and signal-processing experts are engaged in continuous R&D. Their aim is to add new capabilities and improve our products in response to the changing needs of our customers. Applying our knowledge of advanced underwater acoustics technology, eSonar provides solutions for operational challenges with subsea equipment such as operation in the north where ice is a hazard. Our variable buoyancy engine tech can “pop-up” a satellite antenna from submerged equipment to enable communications, detecting if ice is present and resubmerging without damage.
We often work closely with Memorial University in St. John’s NL. Together we have designed and developed creative technological solutions for industry-specific applications and for cross-industry applications such as autonomous underwater vehicles. We work directly with the fishing industry. We work with shipboard marine industries. We work with offshore oil and gas. And we collaborate with many other ocean technology manufacturers and service companies.
An important part of our success is reliability and extended life of eSonar’s sensors through advanced power management. Our engineers apply the latest microprocessors to bring cutting-edge power management to subsea instruments, reducing power demand to micro-watt sleep-state levels, and waking when signaled to greatly extending operating lifetime.
Our synthetic pressure housings are RF transparent, so that equipment settings can be modified, and data can be downloaded via RF link without opening the sealed subsea enclosures. Our enclosures have been tested to 2000m submerged depth.
Our engineering team has capability in high-level and low-level software and firmware capabilities including programmable logic, microcontrollers, Linux hardware drivers, Linux System-on-Module processors, and low power Arm processor types. High-level software capabilities include user interface, signal processing, instrument control, long term monitoring, data collection and storage, data display and bespoke visualization.
As a result of our focus area, and advanced knowledge in acoustics and subsea technologies, our engineers, software specialists, technologists, and technicians are eager to work with customers to deliver next level commercial designs for subsea applications.
We have extensive capability to support ultra-high reliability, low-baud rate, underwater acoustic data communications, with associated expertise in underwater packaging, subsea battery systems, ultra-low power standby systems using a multi-tone wakeup sequence, and individual addressing to provide thousands of unique subsea addresses.
