Frequently Asked Questions
How does the system maintain accuracy when GPS/GNSS signals are lost?
The system relies on its high-precision internal optical or laser gyroscopes and accelerometers to perform dead reckoning, calculating position and orientation continuously without external assistance.
Can these inertial navigation systems integrate with external acoustic devices like DVL?
Yes, our systems feature versatile data interfaces and built-in filtering algorithms that readily accept inputs from Doppler Velocity Logs (DVL), GPS, and compasses for hybrid navigation.
What is the typical lead time and calibration process for custom orders?
Standard configuration units typically ship within 2 to 4 weeks. Custom integration or specialized calibration protocols may require 4 to 8 weeks to complete thorough environmental testing.
