Inertial Measurement Unit for Trajectography

Abstract

This document presents a technological breakthrough regarding electro-optics systems used for accurate measurement of the position of flying objects in Test Ranges. The innovation presented here consists in using an “Inertial Measurement Unit” (IMU) installed as close as possible to the optronic sensors in the core of the payload. After automatic alignment and self-calibration operations, the IMU delivers directly both accurate trajectory angles azimuth (true bearing) and elevation (above the horizontal plane).
