FAQ

Q1: How does zero bias stability affect navigation accuracy?

A: Low bias stability (≤0.5 µg) minimizes long-term drift, directly reducing position/velocity errors in INS systems.

Q2: What is the scale factor and how is it used?

A: Scale factor (ppm-level calibrated) converts acceleration codes (0x1C–0x1E) to g: Acceleration (g) = Code / Scale Factor.

Q3:How does temperature affect measurement accuracy?

A: Built-in temperature sensor outputs 16-bit data (0x1A–0x1B) for real-time compensation.
