FAQ

Q1: What is the impact of zero bias stability on navigation accuracy?
Engineering: Zero bias (≤0.1 mg) translates to position error via double integration (Δpos = 0.5 × bias × t²). Commercial: In 10-hour autonomous vehicle trips, uncompensated sensors drift by ~0.5m; XDA-315 maintains <0.1m accuracy.
 
Q2: How does temperature affect acceleration measurement precision?
Engineering: Temperature coefficients (TC) cause scale factor drift (0.01%/°C). XDA-315’s integrated temp sensor (±5°C) compensates. Commercial: In -40°C to +85°C environments (e.g., engine compartments), XDA-315 maintains <0.1g accuracy.
 
Q3:Can this sensor maintain precision in high-vibration/shock environments?
Engineering: 2000g shock (4.5ms) and 20g vibration (20–2000Hz) pass through robust packaging. Commercial: Used in construction cranes, where 20g vibration would cause 0.05g drift; XDA-315 stays within 0.1g.
