LISA-4000 AHRS
Inertial Reference and Navigation System

LISA-4000 belongs to the family of Strap Down Inertial Reference and Navigation System. It provides necessary Navigation functions for mission success. LISA-4000 performs two distinct basic functions:


  • The Flight Reference function provides Heading and Attitude for Display / autopilot and anti-aliasing filtered body angular rate and linear acceleration data for autopilot inner loop stability augmentation

  • Navigation is performed by coupling the LISA 4000 with a Doppler Radar and Air Data Computers or with a GPS. As a navigator, LISA-4000 outputs high speed inertial velocity data required for accurate weapon release
