FAQ

Q1: How does zero-bias stability impact navigation accuracy?
Engineering: Low zero-bias stability (e.g., XDA-205’s ±5 mg) reduces position/velocity errors in INS systems, as drift accumulates over time. Commercial: In autonomous vehicle navigation, XDA-205’s stability ensures 0.1% position accuracy over 100 km, critical for safety-critical applications.
 
Q2: What are the differences between MEMS and quartz accelerometers?
Engineering: MEMS uses microelectromechanical structures (lower cost, smaller size), while quartz offers higher long-term stability. Commercial: XDA-205 (MEMS) suits industrial IoT and consumer electronics, while quartz dominates high-precision inertial systems like aerospace.
 
Q3:How does temperature affect measurement accuracy?
A: Engineering: XDA-205’s integrated temp sensor compensates for thermal drift (0.02 mg/°C), maintaining ±5 mg zero offset across −40°C ~ +85°C. Commercial: In mining machinery, XDA-205 ensures consistent vibration data despite temperature swings from 0°C to 60°C.
