FAQ
- How does the accelerometer's zero bias stability affect navigation accuracy?
- For ship INS, AC-3A ensures sub-meter accuracy for 24-hour oceanic missions, critical for maritime logistics
- What are the differences between MEMS and quartz accelerometers in practical applications?
- AC-3 is preferred in military and industrial settings requiring decades of operation without calibration, e.g., bridge health monitoring.
- How does temperature change affect acceleration measurement accuracy?
- In marine environments, temperature swings from 20C to 40C cause minimal error, ensuring consistent data for ship stabilization systems.
- Can this sensor maintain accuracy in high-vibration or shock environments?
- AC-3 withstands 10g vibration (20-2000 Hz) and 150g/4.5ms shock, thanks to its robust quartz structure.
- What is the typical pre-delivery calibration process?
- Reduces system integration time for aerospace clients by ensuring each unit meets 5 g bias and 0.2 mA/g scale factor.
- How does noise density impact inertial navigation system (INS) performance?
- In GNSS-denied environments, INS accuracy depends on accelerometer noise; AC-3 ensures position error <1 meter over 100 km flight paths for military drones.
- What causes long-term drift in accelerometers?
- In bridge health monitoring, long-term drift causes misinterpretation of structural stress; AC-3 ensures accurate load tracking for decades.
- Can it be used in GNSS-denied navigation systems?
- Yes, as it provides inertial measurement with natural frequency 350-800 Hz and bandwidth 800-2500 Hz for dynamic input.
- How to compensate for scale factor errors during system integration?
- In ship INS, scale factor errors cause heading drift; AC-3 linearity ensures <0.2 mA/g error, requiring minimal system adjustments.
- What is the expected long-term stability without re-calibration?
- For industrial bridge monitoring, this ensures sub-millimeter accuracy over 10 years, avoiding costly inspections and ensuring safety compliance.
