AUSMOS: Automated Utility Service Mark-Out System


AUSMOS: Developing the Future of Underground Mapping

AUSMOS is an autonomous robotic platform that detects and marks-out below-ground infrastructure utilizing a sensor suite comprised of ground penetrating radar and electromagnetic sensors. This robotic platform automatically collects and processes sensor data to carry out same-day interpretation and mark-out of the ground to enhance damage prevention and protect workers across a wide range of applications.

Key Benefits

On-Site Data Processing

AUSMOS delivers immediate, interpretable results and mark out in the field in near-realtime to remove the need to wait for data analysis by subject matter experts.

High Resolution 3D Map
AUSMOS’ localization and navigation system allows for denser data collection compared to a human operator. This data set is then utilized to create high resolution 3D models of the buried assets.
Improved Data Acquisition

The pushcart data acquisition process is prone to human error. Deployment of AUSMOS ensures data is properly captured and results in a more accurate map. 

Operation in GPS-Denied Environments

AUSMOS can maintain its navigation and localization accuracy in highly congested areas
and inside buildings where GPS is denied. 

Multi-Sensor Assessment
The AUSMOS robot simultaneously collects GPR and EM data and overlays the results of both sensors in one 3D model of the assets for a comprehensive assessment of the infrastructure prior to excavation.
Ease of Deployment

AUSMOS eliminates the manual, intensive setup required for grid marking prior to data collection to reduce time-in-street and increase project efficiency.

How it Works

AUSMOS features a sensor suite comprised of Ground-Penetrating Radar (GPR) and Electromagnetic (EM) sensors encased on a small mobile frame.

Once navigated onto site by the operator, the scan area is then programmed into AUSMOS’ user interface to then autonomously collect and process data on-site for same-day interpretation and mark-out with centimeter-level accurate localization.

Onboard LiDAR enables the robotic platform for autonomous navigation even in GPS-denied environments, such as congested urban areas where signals get scattered.

AUSMOS saves time before operations with ease of setup and deployment, as well as post-scan by instantly delivering denser, easily understandable 3D data with no need to be sent out to subject matter experts.

Use Cases

  • Support project planning with accurate as-built details
  • Identify optimal excavation and trenching locations
  • Minimize risk of subsurface excavation damage
  • Reduce potholing to verify asset locations
  • Support infrastructure and construction activities
  • Un-locatable assets or “Turnbacks”

Data Comparison

Traditional Data Capture

Traditional cart-based deployment of GPR delivers A-Scan hyperbolas that require analysis by subject matter experts.


AUSMOS Data Capture

AUSMOS robotic deployment of GPR delivers 3D Migrated C-Scan / point cloud data that is easy to interpret on site.
