CCSDS Packet Input Stream¶

Splits a stream of consecutive CCSDS Space Packets. For each next packet, the implementation reads the first 6 bytes (= primary header). The last two bytes of this header (plus one) determine the length of the remainder of that packet.

Class Name¶

org.yamcs.tctm.CcsdsPacketInputStream

Configuration¶

This can be used in the configuration of a stream-based packet data link in etc/yamcs.instance.yaml. Example:

dataLinks:
  - name: file-in
    class: org.yamcs.tctm.FilePollingTmDataLink
    stream: tm_dump
    incomingDir: incoming/
    packetInputStreamClassName: org.yamcs.tctm.CcsdsPacketInputStream
    packetInputStreamArgs:
      maxPacketLength: 1500
    # ...

Configuration Options¶

maxPacketLength (integer): Maximum allowed size of each packet in bytes. Default: 1500
