Marine Applications


  • Hydrographic survey – seafloor mapping, underwater detection/exploration, bathy LiDAR
  • Dredging
  • Search and rescue operations
  • Offshore positioning/drilling operations
  • Accurate assessment for pipeline routing
  • Mapping and monitoring of underwater habitats
  • Current and sediment monitoring


  • NovAtel’s SPAN® technology couples NovAtel’s GNSS receiver technology with an Inertial Measurement Unit (IMU). We offer a variety of IMUs to provide the accuracy required by each application. In marine mobile mapping applications higher grade IMUs are typically required.
  • Enclosures, cards and MEMs IMUs have all been integrated at the OEM level.
  • Maximize the performance of your GNSS/INS hardware by getting the position, velocity and attitude accuracy your application requires with assistance from Waypoint post processing tools.
  • Integrate NovAtel’s SPAN technology with multi-beam, single-beam, side-can sonar and other sensors to achieve the best results.
  • ALIGN heading solutions are required to generate precise positioning and heading for the hydrographic market.
  • The ability to input INS updates for submerged applications using a Remotely Operated Vehicle (ROV) or an Automatic Underwater Vehicle (UAV) providing accurate, real-time positioning.
