SSFDR is a three LRU (DAU, RU & CIU) Airborne system. It acquires data like analog signals, discrete signals, tacho, audio signals, MIL1553B data, ARINC 429 data and ARINC 717 data. A 10GB flash memory is integrated for Day to Day analysis. A crash protected memory of 320 MB is available. Data Milk out is through Ethernet Interface.

This was a total turnkey project of full product life cycle development involving requirements analysis, design & analysis, development, engineering, software development (Firmware & Device Drivers), system integration and testing and qualification of the system. System is qualified as per MIL-STD-810F and MIL-STD-461D.
