  • High Rate Data Inputs. The softFEP receives one or more input channels as serial data streams (data/clock) or via Ethernet (TCP/IP or UDP).
  • Data Buffering. The received data streams are queued (buffered) to protect against data overflow from the continuous, real time inputs.
  • Frame Synchronization. Individual frame synchronizers lock on each input data stream to enable downstream processing. The sync strategy, sync patterns, and frame lengths are fully programmable.
  • CCSDS Processing. The softFEP performs the full suite of CCSDS processing functions, including Reed-Solomon decoding, virtual channel sorting, data encapsulation, and packet assembly/sorting.
  • Custom Processing. The softFEP architecture allows customers to add specialized processing in the software. Examples of delivered extension include contact scheduling, merging of data streams, data filtering, error checking, and creating composite files.
  • WAN Rate Buffering. The processed data is delivered over local and wide area networks for additional downstream processing. The network transport protocols within the softFEP system ensure reliable delivery and can perform rate buffering if the network bandwidth is less than the downlink data rate.
  • VHR Compatible. The softFEP pairs with multiple high-rate modems, including the VHR-400, -600, and -1200 from ViaSat. VHR modems and Payload Processors have been delivered to multiple customers.
  • Data Recording. Recording of the payload data streams is an integral function. Recording occurs in parallel with the real time processing. Both raw and processed data can be recorded.
  • Built-In Bit Error Rate Tests. The softFEP generates test data streams that are looped back as inputs to the system. There are built-in BERTs for each data channel.
