The Rapid Airborne Multibeam Mapping System is a lightweight, easily mobilised airborne lidar bathymetric (ALB) system developed by Fugro and Areté Associates. It delivers high-quality coastal and nearshore bathymetric datasets in a fast and cost-effective manner.

RAMMS dramatically improves upon existing airborne bathymetric surveying techniques. Unlike traditional ALB systems, which require a trade-off between data density and depth penetration, RAMMS delivers 25,000 range observations per second while achieving 3-Secchi disk depth penetration. The resulting high-resolution bathymetry data is comparable to that derived from multibeam echosounder systems.

In addition to better quality data, RAMMS provides multiple operational efficiencies over standard ALB systems. Compact in size and weighing just 14 kg (30 lb), the sensor can be deployed in small aircraft or uncrewed autonomous vehicles (UAVs) for reduced mobilisation costs and increased mission times. The sensor is also highly reliable due to its air-cooled, low-energy pushbroom laser which is free of moving parts. Its ability to be used in UAVs makes it cost-effective to acquire data in remote project locations.

Mission data is transferred from the field to Fugro’s processing facilities daily using Back2BaseTM technology, enabling rapid quality assurance review and fast data production and delivery.

RAMMS can be deployed on its own or combined with other remote sensing technologies to address a wide range of bathymetric, topographic, and imagery needs from a single airborne mission. Applications include:

  • Nautical charting
  • Bathymetric mapping
  • Marine and coastal engineering
  • Habitat mapping
  • Coastal zone management
  • Support for storm surge/inundation modelling
  • Oil and gas industry support

RAMMS offers enhanced lidar bathymetry depth penetration and higher point densities, while also improving project timelines and value.

Key benefits include:

  • Better quality data at the same or reduced cost
  • Less system downtime
  • Faster data turn-around
  • Efficient mobilisation
  • Increased aircraft versatility
  • Improved access to remote locations
  • Compatibility with other airborne sensors (data integration)
