High Performance ± 300 °/S MEMS Gyroscope with Digital Interface

High bias stability for precision navigation and positioning in dynamic applications

GYPRO®4300 is a high-performance, closed-loop digital MEMS gyroscope with ± 300 °/s input range that offers a cost-effective alternative to entry-level Fiber Optic Gyroscopes (FOG) and Dynamically Tuned Gyroscopes (DTG) at a fraction of their size, weight, and power consumption.

Its high bias stability and vibration rejection make GYPRO®4300 an industry-leading MEMS sensor to build high-performance IMU (Inertial Measurement Units) for attitude and motion control systems, as well as INS (Inertial Navigation Systems) for GNSS-aided positioning and navigation in dynamic applications.

The hermetic ceramic SMD package combined with a 24 bits SPI interface eases the integration of GYPRO®4300 and reduces the BOM. The built-in self-test ensures initial verification of the sensor’s integrity and continuous in-operation functionality test.

Key performances

  • ± 300 °/s range, single-axis gyroscope
  • Bias instability: 0.5 °/h (typ), 2°/h (max)
  • Angular Random Walk: 0.10 °/√hr
  • Vibration rejection: 0.5 °/h/g²
  • Residual scale factor over temperature range: 230 ppm
  • Latency: ≤ 1 ms
  • Mean Time Between Failure (MTBF): > 1 000 000 hours
  • Available in 3 frequency ranges to minimize mechanical cross-coupling in multi-axis applications

Key features

  • 24-bit digital SPI interface
  • Initial and continuous self-test
  • Factory-calibrated over temperature
  • Hermetic ceramic SMD package
  • Non classified under dual-use export control
  • REACH and RoHS compliant


  • INS for GNSS-assisted positioning and navigation of ground vehicles & trains
  • AHRS (Attitude & Heading Reference System) for UAV and e-VTOL
  • MRU (Motion Reference Units)
  • IMU for precision robotics and remotely operated vehicles
  • Stabilization systems
  • Borehole drilling and surveying instruments
