Tactical Grade, Ten Degrees of Freedom Inertial Sensor Data Sheet ADIS16488A FEATURES GENERAL DESCRIPTION Triaxial, digital gyroscope, ±450°/sec dynamic range
The ADIS16488A iSensor® device is a complete inertial system
±0.05° orthogonal alignment error
that includes a triaxis gyroscope, a triaxis accelerometer, triaxis
5.1°/hr in-run bias stability
magnetometer, and pressure sensor. Each inertial sensor in the
0.26°/√hr angular random walk
ADIS16488A combines industry-leading iMEMS® technology
0.01% nonlinearity
with signal conditioning that optimizes dynamic performance.
Triaxial, digital accelerometer, ±18 g
The factory calibration characterizes each sensor for sensitivity,
Triaxial, delta angle and delta velocity outputs
bias, alignment, and linear acceleration (gyroscope bias). As a
Triaxial, digital magnetometer, ±2.5 gauss
result, each sensor has its own dynamic compensation formulas that
