Digital Processing – Line Replaceable Unit (DP-LRU)

Digital Processing – Line Replaceable Unit (DP LRU) is used in aerostat for electronic warfare application.

The project involved design, development and validation of the hardware along with qualification. The rugged chassis receives signals from external world through the SMA connectors. QDR board extracts IF data from these RF inputs. This IF data is further processed by RPB and ESMP board. ESMP board send the processed data to external world through Gigabit Ethernet interface. The VPX Controller card is used for health monitoring & control plane communication.
