Experience in VSSC/ISRO (1968- 2006): 38 years R&D experience in Avionics, VSSC, ISRO.

1983-2006 in Navigation, Guidance and Control systems area : Was responsible for Flight Computer Checkout Systems activities for launch vehicles ASLV, PSLV, GSLV and Advanced missions. Distinguished contribution to India’s National space program in the areas of Real time Test methodology and Automatic test & simulation systems for verification and validation of launch vehicle navigation guidance and control system. Test methodology and concept formulation, high performance computer realization for simulated flight testing in open loop and closed loop modes, Test Data analysis, vehicle data management have been successfully carried out. Flight computers used are tightly coupled, fault tolerant distributed processor systems using state of the art microprocessors (ASIC/i960/68000/6800). Latest systems used 1553 bus and earlier systems used high speed point to point communication.

1968-1983. In Communication area in realizing PCM Decommutation systems and in Instrumentation.
