Even though JAS network protocols offer a guaranteed delivery option, there still exists the possibility of an error being introduced into a packet while it is being created or transferred from memory to the communication channel. To provide an additional layer of error detection all JAS packets shall contain a 16-bit CRC word to allow packet services to verify the integrity of packets. The CRC algorithm that will be used is described in the CCSDS Telemetry Space Data Link Protocol standard. It is based on the International Telecommunication Union (ITU) (formerly known as CCITT) ITU-T V.41 standard.
