In an instrument category all it’s own the Trimble Kestrel seismogeodetic system integrates a high-sample rate strong motion accelerograph with Trimble’s latest GNSS reference receiver technology in a single instrument, delivering quality data and reducing installation time. The low-power, 336-channel GNSS receiver powered by the latest Trimble Maxwell™ 7 Technology, supports tracking of GPS, GLONASS, Galileo, BeiDou and QZSS signals, ensuring the GNSS data is robust and reliable. And, featuring an Advanced National Seismic System (ANSS) Class A force-balance triaxial accelerometer, Kestrel delivers better data at even the quietest sites at 200 Hz and transmits ultra-low latency data for Earthquake Early Warning (EEW).
Using an advanced Kalman filter algorithm Trimble’s 4D Control software combines, 10 Hz GNSS displacements and 200 Hz accelerometer data to produce 200 Hz displacement data in near real-time, eliminating the loss of static offsets that occur when double-integrating accelerometer data.
Kestrel now incorporates on-board GNSS Precise Point Positioning (PPP) using Trimble CenterPoint™ RTX™ technology delivered through the L-Band signal. Trimble RTX remains locked onto the real-world absolute position, which is critical when analyzing and responding to movement data. These features ensure Kestrel’s data recording is not affected during communication delays or complete outages (often occurring during natural disasters), resulting in more complete data ‒ when it matters.
With an IP67 rating, the compact and rugged Trimble Kestrel seismogeodetic system is ideal for deployment in extreme environments including:
- Monitoring civil structures
- Monitoring earthen structures
- Earthquake Early Warning (EEW) Networks
- Volcano monitoring
- Seismic Hazard Mitigation
