The system provides leading edge sonar performance that rivals the best helicopter dipping sonars on the market, fully integrated unmanned operation capability, and rugged construction for reliable operation and simple maintenance in the marine environment.

Advantages over Adapted helicopter dipping sonars due to USV-dedicated design:

  • Capable of sustained acoustic transmissions at both high power and high duty cycle (no need to wait and re-charge a power bank in the SU).
  • System is designed specifically for an extended lifetime operating in the harsh marine environment:
    • Equipment is designed for naval shipboard shock and vibration.
    • On-deck components and materials are selected to withstand the elements, water loading, and corrosion of a small vessel’s open deck environment at sea.
  • Simplified interfaces instead of specialized, aircraft-specific interfaces, simplifying system components and maintenance.

Features
  • Cylindrical body housing transmit and receive acoustic arrays, as well as telemetry, non acoustic sensors, and associated components
  • Collapsing design provides a low-drag compact form factor for deployment and recovery, but expands for operation to provide large, high-performance acoustic arrays
    • Transmit array deploys vertically below body
    • Receive array staves deploys radially out from body
  • Simplified SU requirements enable a reliable design:
    • SU contains no power storage or amplifier components (replaced with dry end amplifier)
    • Simplified, rugged actuation mechanisms

GeoSpectrum produces a wide variety of hydrophones that can be used for a number of applications including marine mammal detection, monitoring blow-out preventers, and subsea construction.

The M509 Hydrus Towed Array is a thin line digital array. The array streams digitized acoustic and non-acoustic sensor data. Hydrus is a low noise, low drag, low power and lightweight array making it ideal for towing from an unmanned vehicle. The Hydrus array can also be customized with greater than 64 channels. The array and tow cable are neutrally buoyant to support low speed tow. Hydrus includes acceleration cancelling hydrophones to minimize mechanical noise. The array is user configurable to less than 2.5 kHz sampling rate, and high/low acoustic channel gain to tailor performance to various applications. Non-acoustic sensors include depth, temperature, roll, pitch, and yaw.

Applications vary from marine surveillance, marine monitoring, anthropogenic noise monitoring, and detection applications.

The M20 is an excellent choice for applications benefiting from direct measurement of particle motion. GeoSpectrum’s particle motion sensors are suitable for a variety of different applications including marine mammal detection, ocean environmental monitoring, antisubmarine warfare (ASW), marine surveillance, offshore oil and gas monitoring, and offshore wind farm monitoring.

The M20 family is a group of sensors that measure particle motion with high sensitivity and good directivity down to very low frequencies.

GeoSpectrum’s particle motion sensors are accelerometer-based and are used to measure 2D or 3D particle motion or as a low-frequency directional hydrophone in a broad range of environments—from within 1 m of an air gun to quiet ocean environments.

Because the sensor maintains good directivity to very low frequencies, it also supports acoustic applications requiring good low-frequency bearing detection in a very small package.
