  Receiver/Decoder Qualification (CRD)

Problem: Integrated Receiver Decoder (IRD) obsolescence created a redesign requirement.
Solution: Development of a next generation Receiver Decoder, Command Receiver Decoder (CRD), combines the current IRD and Range Safety Distributor (RSD) functions into a single housing. The design will incorporate the Direct Current Firing Circuit (DCFC) in lieu of the Pyrotechnic Initiator Controller (PIC) for ordnance initiation. The CRD will eliminate obsolete parts, simplify design, add improved manufacture ability, reduce weight and power consumption.
Initial Operation Date: Complete Qualification 8/99
Number of Shuttle mission-TBD
Technology Goal: No new technologies involved
Goals Supported: 2) Meet the Manifest
3) Improve Supportability
4) Reduce Cost
