FAQ

Q1: How does bias stability affect navigation precision?
A: Bias stability ≤50 µg over 1000h minimizes long-term position drift. In INS systems, even 1 µg drift accumulates to meters over hours, making this critical for autonomous vehicles or GNSS-denied tunnels.
 
Q2: How do temperature variations impact accuracy?
A: The integrated 16-bit temp sensor (±5°C absolute) compensates thermal errors. For example, in automotive engines, temp swings from -40°C to 85°C are mitigated via real-time data adjustments, ensuring ±0.1% accuracy.
 
Q3:Is this sensor suitable for high-vibration environments?
A: Yes, with vibration resistance up to 2000Hz (20g RMS). Ideal for construction machinery, where 200Hz vibrations would otherwise corrupt readings.
