The Aeronautical Development Establishment is a laboratory of India's Defence Research and Development Organisation (DRDO). Located in Bangalore, its primary function is research and development in the field of military aviation.[2]Its recent successful projects include Lakshya (an aerial target), Nishant (a reconnaissance UAV), flight simulators (LCA, Ajit, Kiran, Mig-21) and avionics packages for Tejas-LCA (display and FCC). It earlier worked on Sparrow (mini-uav) and Ulka (aerial target). Many new projects are being planned there.This establishment was the place where former Indian president A.P.J. Abdul kalam started his career.
