Question 1

How does zero bias stability affect navigation accuracy?

Accepted Answer

In autonomous trucks, uncompensated drift would lead to path deviations exceeding safety margins, requiring costly re-calibration.

Question 2

What are the differences between MEMS and quartz accelerometers?

Accepted Answer

MEMS suits automotive ADAS; quartz powers missile guidance and satellite navigation.

Question 3

How does temperature affect measurement accuracy?

Accepted Answer

In Arctic oil rigs or desert mining, this ensures reliable data collection even in extreme thermal cycles.

Question 4

Can the sensor maintain precision under high vibration/shock?

Accepted Answer

In construction cranes monitoring load shifts during high-vibration operations ensures load safety by detecting sudden overloads.

Question 5

What's the typical factory calibration process?

Accepted Answer

Clients receive pre-calibrated coefficients, reducing integration time by 30% in industrial IoT sensor networks.

Question 6

How does noise density impact INS performance?

Accepted Answer

In UAV navigation during GPS denial (e.g., urban canyons), low noise ensures stable flight paths with sub-meter accuracy.

Question 7

What causes long-term drift in accelerometers?

Accepted Answer

In geotechnical monitoring (e.g., dam deformation), stable drift ensures accurate long-term structural health assessments.

Question 8

Is it suitable for GNSS denial environments?

Accepted Answer

In drones or underground mining, this ensures continuous operation by combining accelerometer/gyro data for position updates.

Question 9

How to compensate scale factor errors during integration?

Accepted Answer

In autonomous ships, real-time scale factor compensation ensures accurate speed and position calculations for collision avoidance.

Question 10

What's the expected long-term stability without re-calibration?

Accepted Answer

In smart grid sensors (e.g., transformer vibration monitoring), this reduces maintenance costs by eliminating frequent calibration visits.**
