Physical Initial Flight Alignment For Stabilized Platform Inertial Navigation system Using State Feedback

Seyed Ali Zahiripour

Volume 17, Issue 1 , March 2024, Pages 1-9

Abstract
  A method for increasing the accuracy of the initial alignment process of inertial navigation systems with a stable platform is presented through state feedback control in flight mode. In the presented method, the state feedback controller is designed by using the stable plate deviation angles and the ...  Read More

Design and Fabrication of Planar Sub-Array for Satellite Data Transmission Directive Conformal Array Antenna

Arian Zakiani; Seyed Hassan Sedighy; Razieh Narimani

Volume 17, Issue 1 , March 2024, Pages 73-79

Abstract
  Due to the limited communication time between LEO satellites and the ground station and large volume of satellite image data, it is necessary to establish a high transmission rate connection. Therefore, the use of a high-efficiency satellite antenna is inevitable. In order to use the limited viewing ...  Read More
