Ocean Mapping

Autonomous high-resolution mapping data to 7,000 m depth for navigation and charting, telecommunications, offshore energy, exploration, characterization, and physical oceanography—at a fraction of the cost of traditional survey methods.

Capabilities

Reconnaissance Single-beam
Saildrone Explorer equipped with an Airmar DT800 echo sounder for single-beam reconnaissance missions (e.g. contour line mapping) meeting IHO Order 2 survey requirements in areas up to100 m deep. Especially useful in remote areas with sparse bathymetric information such as the Arctic.
Shallow Multibeam
Saildrone Explorer equipped with a Norbit iWBMS high-resolution multibeam echo sounder and sound velocity profiler (SVP) for shallow water multibeam surveys that meet IHO standards up to 400 m deep.
Deep Single-beam
Saildrone Explorer equipped with a Teledyne Echo trac E20 for deepwater single-beam surveys that meet IHO survey standards in areas up to 500 m deep.
Full Ocean Multibeam
Saildrone Surveyor equipped with Kongsberg EM2040 and EM304 forlarge-scale bathymetric surveys in the ocean up to 7,000 m deep.

Saildrone Surveyor Demonstrates Exceptional Mapping Capabilities During First Trans-Pacific Crossing

Saildrone’s flagship autonomous, uncrewed surface vehicle (USV) arrived in Hawaii on June 8, 2021, after a groundbreaking 2,100-nautical mile maiden voyage from San Francisco to Honolulu. Watch the video to learn more about the Surveyor's exceptional ocean mapping capabilities.

Saildrone’s fleet of small and medium uncrewed surface vehicles (USVs) provide near-shore and open-ocean bathymetry solutions that meet or exceed International Hydrographic Organization (IHO) standards.

Additional Capabilities Include:

  • Near-real-time acquisition monitoring
  • Motorized for maneuverability
  • On-board data processing
  • Seafloor classification
  • High-resolution feature mapping
  • Nautical chart validation
  • Comprehensive metocean sensor suite
  • Arctic and remote area exploration

Saildrone Surveyor Discovers New Sea "Hill" Off the Coast of San Francisco

The Saildrone Surveyor successfully mapped an uncharted area of the ocean 140 nautical miles off the coast of San Francisco discovering a completely unknown 2,600-foot (800 meter) sea “hill”.

Saildrone Surveyor Launch - January 2021

The first in the Surveyor class of USVs, the Saildrone Surveyor carries sonar equipment capable of seafloor mapping down to 7,000 m.

Saildrone Vehicles

Saildrone Explorer – 7 m (22 ft) Uncrewed Surface Vehicle

The 7 m Saildrone Explorer is designed to carry a payload of sensors to collect data above and below the sea surface. A 5 m wing provides wind power for forward propulsion and solar panels power onboard science and navigation instruments. Saildrones can be equipped with an acoustic payload for specific mission requirements: a single-beam or multibeam sonar for bathymetry, an echo sounder for fisheries surveys, or an ADCP for current measurements.

Saildrone Surveyor – 22 m (72 ft) Uncrewed Surface Vehicle

The 22 m Saildrone Surveyor is a wind and motor power combined solution: It transits autonomously to and from any area of the ocean under wind power and uses the engine to perform IHO-compliant surveys. 

The Saildrone Surveyor is outfitted with two multibeam echo sounders of differing frequencies, providing the capability to collect full-coverage, high-resolution bathymetry to depths up to 7,000 meters. The vehicle is also equipped with a suite of single-beam echo sounders, two Acoustic Doppler Current Profilers (ADCP), a Moving Vessel Profiler (MVP), and a CTD sensor to collect water column and seafloor characterization data.

With a speed of 10 knots, the Saildrone Surveyor provides persistent and scalable bathymetry capabilities in the most remote areas of the ocean—and in any weather conditions.
