Prof. M. R. Ananthasayanam

Retired Professor, IISC Bangalore.

· Prof. M. R. Ananthasayanam has contributed extensively to the field of Aerospace Engineering, in a career spanning more than 50 years.

· His research activities and contributions include about 200 publications spread over reports, conferences, and journals and has guided many M.Sc. and Ph.D. Theses.

· He was involved in consultancy and design reviews for ISRO and DRDO.

· He has been a reviewer for Current Science, Acta Astronautic, Journal of Spacecraft and Rockets and many more.

· After his B.E. in Electrical Engineering from Madras University in 1961, he joined the Department of Aerospace Engineering at IISc, where he obtained his M.E. and Ph.D. He has been affiliated with the IISc until 2004, when he retired as Professor.

 

· His Ph.D. thesis was on flight safety with Prof. Narasimha as advisories a spin off from their work for Prof. Dhawan’s AVRO Evaluation Committee. Subsequently they proposed the Indian Standard Tropical Atmosphere and the International Tropical Reference Atmosphere from sea level up to 2000 km. Invited speaker at COSPAR meeting held at Ottawa, Graz, and Beijing.

· He has been a Member of the Task Team to revise the COSPAR 1972 document. He further contributed to airworthiness, flight safety, and for the modeling of space debris, and ionosphere. Apart from research, his teaching, development, and consultancy activities also led invariably to research publications.

· He has contributed extensively to the application of Kalman filtering for state and parameter estimation, in diverse areas such as aerospace through many MSc and PhD theses in flight test data analysis, tracking of aircraft and missiles, space debris, ionosphere, GPS/INS integration, attitude estimation and docking of spacecraft, and tomography. He continued his research pursuits after retirement.

 

· He has around 200 publications in the form of departmental reports, project reports, confidential reports for the AVRO evaluation committee and DRDL flight tests, edited conference and workshop publications, Conference publications, and Journal publications.

 

· His vast research experience culminated in the recent publications [SADHANA, 2016] with his associates, provided the Reference Recursive Recipe for the notorious problem of tuning the Kalman filter statistics existing ever since1960 Kalman proposed the filter.

 

· With the above it is envisioned that a proper application of the filter will never be the same again.

 

· He is a recipient of the Platinum Jubilee Distinguished Service award of the department of Aerospace Engineering, Indian Institute of Science, Bangalore in 2017.
