AVIONICS SYSTEMS – DESIGN & CHALLENGES
Electronics systems used in an aerospace vehicle are together called avionics systems. Design of avionics for missile systems poses unique challenges with respect to hardware complexity, hard-real-time software, environment they function, qualification testing requirements and reliability. Another important challenge is the synchronization of all on-board avionics sub systems and ground systems to realize mission objectives. This talk gives an overview of various missiles avionics sub-systems, their features, design aspects and challenges and qualification testing requirements.
Missile avionics is different from other embedded systems in terms of their ruggedization, qualification and certification requirements. The examples of such systems are On Board Mission Computers, Navigation Systems, Control Actuation Systems, Seekers and Flight Instrumentation. Most of these systems will be covered in this talk highlighting the challenges during the design, qualification and testing.
Shri BHVS Narayana Murthy is presently Director, Research Centre Imarat (RCI), DRDO. He is an Aerospace Scientist well renowned for his R&D in Missile technologies and sustained contributions towards advancement of Aerospace industries in India. As Director, Research Centre Imarat, the Avionics laboratory founded by Dr APJ Abdul Kalam, he is spearheading the development of Avionics technologies in critical areas of Navigation, Embedded Computers, Control, Guidance, Simulation, RF and Infrared Imaging Seekers, Telemetry for Indian Missiles and other defence programmes.
For last three decades he has made significant national contributions towards Design, Development and Delivery of Onboard Computers, Missile Launch Processors, Real-time Mission softwares with novel fault tolerant schemes and System on Chip for missions of national significance. Mr Murthy pioneered the development of embedded computers and other critical Avionics sub-systems which have been successfully flight tested in all the three missions of the country’s first ICBM class Agni-5 missile with range of more than 5000kms. His technological contributions have left a lasting imprint on the technology map as well as the defence preparedness of the country.
As Project Director, Mr Murthy developed the Smart Anti Airfield Weapon bolstering weapons capability of Armed forces. He led the development and production of miniaturized SatNav receivers and System on Chip (SoC) bringing in quantum jump in miniaturization of Onboard Avionics.
Mr Murthy graduated in Electronics and Communication Engineering from REC, Warangal and received his M.Tech from JNTU, Hyderabad. For his significant lifetime contributions to Aerospace engineering, Mr Murthy has been inducted as Fellow of the Indian National Academy of Engineering. He is also a Fellow of IETE, Senior member IEEE, Life Member of Aeronautical Society and Computer Society of India.
For his pioneering contributions to Defence R&D, he was bestowed with Rocket and Related Technologies Award by the Astronautical Society of India. As a team leader, he received the prestigious AGNI Award for Excellence in Self Reliance. He is also a recipient of DRDO Scientist of the Year Award, Path Breaking Research/Outstanding Technology Development Award and DRDO Performance Excellence Award.
