The meeting discussed the Draft Guidance Material on generation, processing sharing
of ASTERIX Category 21 Messages presented by Hong Kong, China and Australia. The paper
analyzed various aspects in generation, processing and sharing of ASTERIX Category 21 ADS-B
messages. It introduced a concept of grouping ASTERIX data fields (i.e. mandatory, desirable and
optional ADS-B data fields) for sharing of ADS-B data in ASTERIX Category 21 format to ensure
system interoperability and harmonize ADS-B implementation in the Asia/Pacific Region. The paper
also highlights deployment of an ADS-B format conversion and filter (ADS-B FC&F) system in the
overall system design, to enable ADS-B data to be shared with other states in a cost-effective manner
and provide the necessary data protection with flexibility to cope with future changes in ASTERIX
standards. The meeting supported the concept and considered the guidance material should be
adopted, based on the Seamless ATM Planning concept.
