Trimble Kestrel System SG160-09

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.

• Combines Global Navigation Satellite System (GNSS) and seismic accelerometer measurements
• 336 Channel GNSS receiver features Trimble’s latest Maxwell 7 technology and Precise Point Positioning (PPP) technology, delivering centimeter level accuracy over L-band or IP using Trimble’s Centerpoint RTX corrections
• Advanced National Seismic System (ANSS) Class A Triaxial Accelerometer
• Ultra -Low latency data transmission for EEW

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
