Front End Data System (FEDS)
ï Dec-Alpha allows simple integration with MO-Jukebox.
ï Jukebox capacity TBD. Rough estimate given space-
craft and instrument data rates, and expected compression
algorithms and 2 year mission lifetime is 250 Gbytes.
ï Records and Logs all frames to Jukebox.
ï Provides APIís to retrieve time-ordered, duplicate-removed
packets to C, Fortran, IDL, Matlab programs.
ï Provides time-ordered, duplicate-removed packets via
ï Automatic identification of lost/missing frames.
New Developments:
ï Conversion from VME equipment rack to plug-in Ethernet,
bit sync and frame sync/Reed-Solomon decoder cards.
ï Configurable to CCSDS Version 1 or Version 2.
ï Automated generation of ìretransmitî commands for missing frames.
