Class ColumbusCcsdsPacket

java.lang.Object
org.yamcs.tctm.CcsdsPacket
org.yamcs.simulator.SimulatorCcsdsPacket
org.yamcs.simulator.ColumbusCcsdsPacket
public class ColumbusCcsdsPacket extends SimulatorCcsdsPacket
CCSDS packets as used in Columbus/ISS 
 primary header (6 bytes):
 3 bit = version
 1 bit = type (0 = system packet, 1 = payload packet)
 1 bit = 2nd header present
 11 bit = apid
 
 2 bit = grouping, 01 = first, 00 = cont, 10 = last packet of group
 14 bit = seq
 
 16 bit = packet length (excluding primary header) minus 1
 
 secondary header (10 bytes):
 32 bit = coarse time (seconds since 1970)
 8 bit = fine time
 2 bits = time id (see constants)
 1 bit = checksum present (2 bytes after user data)
 5 bits = packet type (see constants)
 32 bit = packet id
