SIS-1 Infrasound Sensor: Cutting-Edge Infrasound Detection for Civil and Military Applications

The SIS-1 Infrasound Sensor, developed in collaboration with CEA, is a high-performance, low-power sensor designed for a wide range of civil and military applications. This portable sensor provides exceptional infrasound detection capabilities, enabling rapid deployment for diverse monitoring needs.


Key Features and Applications

1. Civil and Military Security Solutions
The SIS-1 sensor is versatile in detecting infrasound events across a broad range of applications.

  • Military Applications: Nuclear explosions, missile launches, and drone detection are among the sensor’s critical uses, enhancing defense and security.
  • Civil Applications: SIS-1 also plays a vital role in natural disaster monitoring, including earthquake and tsunami detection, weather-related phenomena like tornadoes and avalanches, and emerging environmental emissions tracking, such as those from wind farms.

2. Exceptional Detection Range
This sensor is designed to detect infrasound events from frequencies as low as 1 Hz, making it a premier solution in the infrasound sensor market. The SIS-1 supports chainable deployment for extensive coverage and offers easy installation and maintenance, making it ideal for both temporary and permanent installations.

3. Innovative System Composition
The portable SIS-1 system includes:

  • Infrasound Sensor: Core to detecting and monitoring infrasound events.
  • Digitizer and Data Transmission: Ensures accurate data capture and real-time transmission.
  • Power Supply and GPS: Self-contained for autonomous deployment and location tracking.
  • Optional Components: Wind noise reduction systems (WNRS) and a weather station enhance accuracy in varied environmental conditions, maintaining the sensor’s reliability.

Advanced Metrology and Testing Standards

Seismo Wave’s metrology standards underscore the sensor’s quality:

  • Dynamic Infrasound Generator: Calibrates and tests the sensor’s infrasound response.
  • Metrology Room: Offers precise control over temperature, ground vibration, and meteorological conditions, ensuring accuracy.
  • Active Vibration Isolation Tables: Assure minimal interference, critical for accurate low-frequency measurements.

Technical Specifications

The SIS-1 sensor features impressive self-noise characteristics and maintains amplitude and phase accuracy, essential for detecting even the faintest infrasound signals. These specifications make it a top choice for applications requiring precision and reliability.


Whether used for civil applications like earthquake detection or military applications for blast and drone detection, the SIS-1 infrasound sensor stands out for its flexibility, chainable configuration, and adaptability to both routine and high-stakes monitoring scenarios. The SIS-1 is a complete, portable solution for organizations that prioritize early event detection and broad monitoring coverage.
