Accelerometer Performance: 3, 6, or 9-Axis Sensors?

Combined Functionality: What do you lose? There is a trend towards combining hardware components and even processors into single chips. This is certainly true for inertial sensors: 3-axis: accelerometer only 6-axis: accelerometer, gyro 9-axis: accelerometer, gyro, magnetometer where each sensor measures three-orthogonal axes, hence the counting by threes. Even the…
