eSonar develops underwater acoustic sensing and custom electronics in St. John’s. Its AUV Innovative Perception work combines compact sonar and related sensing functions for small underwater vehicles, alongside an established commercial focus on fishing-gear monitoring and marine environmental data.
Operating context
The AUV approach is designed around the processing and handling limits of small underwater vehicles. Bottom tracking, obstacle awareness and surfacing clearance complement survey payloads rather than assuming all recorded imaging data can guide the vehicle in real time.
Canadian footprint
Located at 21 Mews Place in St. John’s, Newfoundland and Labrador. The company describes collaboration with Memorial University researchers on underwater acoustics and AUV navigation.
St. John's, NL is the published city-level context for eSonar. It does not imply a street address or exact facility location.
eSonar offers a compact sensing path for small AUVs that cannot carry large imaging payloads or heavy processing. The Aquatec award provides a development counterpart; platform-specific acceptance is the next useful evidence for an integrator.
Interpretation of the public record. Not qualification, endorsement or evidence of buyer interest.
eSonar describes a low-footprint perception suite for underwater vehicles, including micro-AUVs. Bottom-tracking, obstacle and surfacing-clearance sensing aim to provide immediate situational information alongside the vehicle’s survey work; public material does not identify a completed naval mine-countermeasure installation.

Core features
Intended for AUVs down to the 12 cm diameter class
Bottom-tracking and obstacle-awareness sonar
Surfacing-clearance sensing and low-power sonar nodes
Vector hydrophone and surfaced micro-radar options
Offers acoustic products and engineering services; the public AUV pages describe an integration approach without naming a production AUV customer.
Financing and disclosed activity
ACOA’s May 2023 announcement allocated CAD 250,000 to the eSonar–Aquatec winning team to implement and demonstrate an ocean-perception proposal; it did not disclose the allocation to eSonar alone.
Ecosystem relationships
Technology development partner
Aquatec Group
ACOA selected eSonar and the UK’s Aquatec as a Canada-UK Ocean Tech Challenge team in May 2023 to develop an uncrewed-vessel perception sensor suite.
Questions for a first conversation
01
Which AUV platforms have completed integration and acceptance testing of the compact perception suite?
The 2023 funded team and current product description establish a development route, but platform-specific trial results would distinguish available modules from integration work still required.
