K-01IMU

Nine-axis inertial measurement unit / GNSS-aided

Precision inertial sensing for platforms that cannot afford to drift. A temperature-compensated MEMS core, a nine-state fusion filter and a machined aluminium housing — calibrated as one instrument, not nine sensors.

Operating principle

A triad of MEMS gyroscopes and accelerometers, temperature-compensated at the source, fused through a nine-state Kalman filter.

K-01 measures angular rate and specific force on three orthogonal axes. Each sensor is individually characterised across temperature and over its full input range, then compensated in the digital domain before fusion.

The onboard filter combines the inertial solution with an external GNSS velocity or position update, producing a continuous navigation solution at up to 200 Hz. All calibration and compensation coefficients are stored on the instrument, not in the host.

Angular random walk (Allan deviation, 1 σ)σ_ARW = 0.08 °/√h
@ 25 °C, 200 Hz, 24 h integration
01Six-face calibration is performed per serial number before sealing.
02Temperature compensation is applied using an internal 16-point curve.
03All data is output in SI units; no host-side scaling is required.
