Product Details


NS-IMU-MEMS300 replaces STIM300's product features:

1) Three-axis digital gyroscope:

a) ±400o/s dynamic measurement range;

b) zero bias stability (Allan variance @25 ° C): 0.5o / h;

c) random walk: 0.15o/√h;

d) Offset acceleration sensitivity: ≤ 2o / h / g;

e) Gyro bias error within the full temperature range (-45 °C ~ 60 °C, the root mean square value of the zero error of the fixed temperature point relative to the full temperature): ≤ 30o / h.

2) Three-axis digital accelerometer:

a) ±30g dynamic measurement range;

b) zero bias stability (Allan variance @25 ° C): 0.15 mg;

c) random walk: 0.21m/s√h;

d) noise: 270ug/√Hz;

e) Acceleration zero deviation error in the full temperature range (-45 °C ~ 60 °C, variable temperature ΔT ≤ ±1 °C / min, rms value: ≤ 6mg.

3) High reliability: MTBF>20000h;

4) Guaranteed accuracy in the full temperature range (-45 ° C ~ 60 ° C): built-in high-performance temperature calibration and compensation algorithm;

5) Support drone application: suitable for high vibration environment of drones;

6) Support stable platform application: full parameter measurement, measurement bandwidth >100Hz;

7) The data update rate is ≥1KHz.
