Design of Antenna Pointing System (APS)-its control and communication challenges

摘要

UAVs (Unmanned Aerial Vehicles) are essential elements in the military capabilities of every country. They are increasingly being used to carry out the high risk tasks of reconnaissance, surveillance and intelligence collection in combat situations and Target acquisition. Modern UAVs are used for many important application including Coastal surveillance, Disaster Management and news broadcasting. In India, among the various Defence Research and Development Organisations (DRDO), Aeronautical Development Establishment (ADE) is tasked with the development of indigenous UAV systems for armed forces. The various classes of ADE UAVs include tactical UAVs (Nishant), Aerial Target Systems (Lakshya), Medium Altitude Long Endurance (MALE) UAVs (RUSTOM). UAV system consists of a user friendly Ground Control Station (GCS) and the Unmanned Aerial Vehicle. The UAV incorporates a number of airborne processors to handle the communication, Flight control and navigation, as well as very reliable data links.
