Towed Arrays for USVs & UUVs
The M508 Hydrus is a compact digital towed array that delivers high-quality acoustic and environmental data. Its lightweight design and low-drag profile make it ideal for use with unmanned surface vessels (USVs) and unmanned underwater vehicles (UUVs), where space and power consumption are limited.
This array supports digitized signal acquisition from both acoustic and auxiliary sensors, including depth, temperature, and orientation.
Features such as acceleration-cancelling hydrophones reduce mechanical noise, while configurable channel counts and sampling rates provide adaptability for a range of operating needs.
Wideband Omnidirectional Hydrophones
GeoSpectrum Technologies provides a suite of hydrophones with integrated low-noise preamplifiers, tailored for use in scientific, industrial, and defense sectors. The hydrophones are highly configurable, with options for different bandwidths, gain settings, and operational depths.
These units support missions such as subsea construction monitoring, BOP (blowout preventer) acoustic verification, and marine biology acoustic studies.
Acoustic Transducers for Underwater Communication
GeoSpectrum offers a diverse lineup of acoustic transducers for use in communication, sonar, and navigation. These include:
- Benders: Ideal for low-frequency, moderate-power applications like long-range communications and sonar signaling.
- C-BASS: VLF electrodynamic projectors suited to surveillance, navigation, and underwater communication.
- Communications Transducers: Directional, oil-filled devices for mid- to high-frequency communication.
- Free Flooded Rings: Designed for broadband, full-ocean-depth use with toroidal beam patterns.
- Spherical Transducers: Compact units delivering omnidirectional transmission and reception at high frequencies.
These options provide system integrators with flexibility in designing acoustic networks tailored to specific mission profiles.
M20 Series Vector Sensors for Direct Motion Measurement
The M20 family includes 2D and 3D accelerometer-based sensors that directly measure underwater particle motion, providing critical data for studies involving environmental monitoring and platform stability.
These sensors operate across low frequencies with high sensitivity, enabling applications that include energy platform monitoring, behavioral studies of marine species, and detection of anthropogenic underwater noise.
Field-Portable Calibration Systems for Hydrophones & Sources
GeoSpectrum Technologies offers field-deployable systems to ensure accurate calibration of hydrophones and sound sources. The M351 Hydrophone Field Calibrator verifies sensitivity and SPL values before deployment, reducing data inconsistencies and operating risk.
The Portable Acoustic Calibration System (PACS) provides a self-contained test platform for in-house and in-field verification of acoustic sources, supporting more reliable and cost-effective system deployments.
