Manufactured under co-production license from Northrop Grumman Italia (NGI).
The Lisa-4000 performs two distinct basic functions:
- Flight Reference.
- Navigation.
The Flight Reference function provides:
- Heading and Attitude for Display/Autopilot.
- Anti-aliasing filtered body angular rate.
- Linear Acceleration data for autopilot inner loop stability augmentation.
Navigation is performed by coupling the LISA 4000 with a Doppler Radar and Air Data Computer or with a GPS. As a navigator the LISA-4000 also outputs high speed inertial velocity data required for accurate weapon release.
The LISA-4000 therefore provides all the inertial output parameters required for Autopilot, Navigation, Display and Weapon Delivery.
