Omnitech Electronics Incorporated (OEI) is proud of its projects that support scientists around the world. In particular, OEI has worked with Defence Research and Development Canada (DRDC) on many projects over the last 30 years. Below is a list of some of the publications that have been produced with the support of equipment designed by OEI.

NGAS and DUSN autonomous underwater sensor systems

Arctic ambient noise measurements in support of the Northern Watch Project
Prepatory work using DRDC's NGAS/Starfish to characterize the environmental conditions before final development of the NWUSS acoustic arrays.

Distributed Underwater Sensor Networks CFMETR Field trial Spring 2018
OEI provides development support for DRDC's research into distributed underwater sensor networks that provide surveillance capabilities through networked autonomous devices.

DRDC Starfish Acoustic Sentinel and Phase Gradient Histogram Tracking
While the scientists develop new methods to monitor, process, and interpret the surveillance environment, OEI supports them phyiscal implementations of the hardware and optimization and embedding of the processing algorithms.

Passive Acoustic Arrays

The Whale Binaural Rings Experiment
OEI’s hydrophone arrays help researchers detect and locate North Atlantic right whales over long distances in the Gulf of St. Lawrence.

Development of low-cost underwater acoustic array systems for the Northern Watch Technology Demonstration Project
Initial development efforts of the Northern Watch acoustic arrays.

Overview of the technical results of the Northern Watch Project
A detailed report on the NWUSS project over many years.

Canadian Arctic Underwater Sentinel Experiment (CAUSE)-Gascoyne Inlet Camp 2017 field trial
One of many trips DRDC has made to the Canadian Arctic to monitor the Northern Watch underwater passive acoustic arrays.

Signals of Opportunity based Geometry Calibration of Hydrophone Arrays
The Swedish Defence Research Agency (FOI) has used the PASS-2447 arrays for many years. This is one of the publications produced using data from these arrays.

Acoustic Homing

The Evolution of an Acoustic Homing System for Underwater Vehicles
Testing of the novel homing system used by DRDC in support of the Canadian submission to the United Nations Convention on the Law of the Sea (UNCLOS).

Project Cornerstone – Using AUVs for Bathymetry Measurements in the Arctic
Presentation detailing DRDCs plan for UNCLOS support.

12 days under ice--a historic AUV deployment in the Canadian High Arctic
Details of historic autonomous under-ice traversal.

Short range localization of Autonomous Underwater Vehicles
OEI’s acoustic homing device helps autonomous underwater vehicles navigate beneath Arctic ice, guiding them toward an acoustic beacon from more than 50 km away.

Acoustic Localization of an Autonomous Underwater Vehicle
Early Arctic trials explored acoustic localization for ISE-built AUVs, ahead of the deployment of OEI’s acoustic homing device for under-ice missions.
