Ideal for maritime defence and homeland security, Lilypad is comprised of moored, uncrewed, mono/multi-sensor platform(s) which can be strategically placed to expand maritime warning and enhance coastal defense capabilities. Lilypad enables persistent surveillance and expanded coverage reducing the need for expensive, conventional patrol methods such as surface vessels and Maritime Patrol Aircraft. Lilypad is capable of operating in a standalone configuration or as multiple platforms to expand coastal coverage as required. Fully customizable and capable of expansion to suit changing defence technologies.

]]> Particle Motion Sensor https://geospectrum.ca/product/particle-motion-sensor/ Tue, 13 Jun 2023 21:13:08 +0000 https://geospectrum.ca/?post_type=product&p=7490 Low-Frequency particle motion sensing

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.

]]> C-Bass https://geospectrum.ca/product/c-bass/ Thu, 20 Apr 2023 17:25:23 +0000 https://geospectrum.ca/?post_type=product&p=7307 GeoSpectrum’s C-BASS transducers are suitable for a wide variety of very low frequency (VLF) applications including use as calibration sources, active sonar acoustic surveillance, acoustic targets for sonar training and acoustic trials, acoustic communication with ranges exceeding 1,000 km, underwater navigation networks, acoustic thermometry, and diver deterrence. C-BASS also provides broadband coherent acoustic mimicry of anthropogenic noise (i.e. offshore wind, construction, pile driving, etc.)

C-BASS is a novel family of very low frequency (VLF) electrodynamic sound projectors. These powerful electrodynamic projectors are less expensive, lighter, smaller, more efficient, and have a broader bandwidth than their peers. C-BASS makes possible applications that were previously impractical.

GeoSpectrum offers a wide range of standard C-BASS configurations with operating frequencies ranging from below 10 Hz up to 3 kHz and maximum source levels that exceed 200 dB re 1 µPa @ 1m. Our finite element analysis and modeling tools and significant build experience enable us to customize C-Bass designs to customer specifications. The omni-directional C-BASS can be used individually or in arrays to produce high-power sources with or without directivity.

C-BASS are offered as stand-alone transducers for customer integration or as a GeoSpectrum-provided system that can include VLF amplifiers, pressure compensation, signal controllers, tow bodies, deployment cables, and winch systems.
