Detailed Description

Represents the primary header of a CCSDS packet.

This structure is used to encapsulate the key fields of the CCSDS primary header.

Fields:

versionNumber: 3-bit field indicating the version of the CCSDS standard.
type: 1-bit field indicating the type of the packet (telemetry or telecommand).
dataFieldHeaderFlag: 1-bit field indicating if a secondary header is present.
APID: 11-bit field identifying the application process.
sequenceFlags: 2-bit field indicating the sequence type of the packet.
sequenceCount: 14-bit field indicating the sequence number of the packet.
dataLength: 16-bit field specifying the data length of the packet payload.
