Helmet-Mounted Attitude Control Algorithms of the Opto-Electronic Surveillance System for Aircraft Search and Rescue Actions

摘要

This article presents selected results of work concerning the errors modeling of helmet-mounted cueing systems used for guided weapon and opto-electronic surveillance systems target homing (for realizing aircraft search and rescue actions). There were described algorithms of helmet angular position determination on the basis of inertial and magnetic methods, moreover, the possibilities of their modification. On this background there were presented the authorial method of pilota??s helmet angular position determination dedicated for helmet-mounted cueing systems for fighter helicopters. The method is based on the pilota??s helmet and aircraft body linear accelerations measurements, which then are used for the current quaternion evaluation to describe the helmet position relatively to the aircraft. Simulation models were tested in Matlab-Simulink and Borland C++ computational packages for various pilota??s helmet space orientation using specialized rotation test stands.
