Description / Abstract: This International Standard specifies a standard message format for use in exchanging spacecraft conjunction information between originators of Conjunction Assessments (CAs) and satellite owner/operators and other authorized parties. Such exchanges are used to inform satellite owner/operators of conjunctions between objects in space to enable consistent warning by different organizations employing diverse CA techniques.

This International Standard:

a) facilitates interoperability and enable consistent warning between data originators who supply CA and the satellite owner/operators who use it;

b) facilitates automation for the CA processes; and

c) provides critical information to enable timely CA decisions.

This International Standard includes requirements and criteria that the message format has been designed to meet. Also included are informative descriptions of conjunction information pertinent to performing CA.

The scope and field of application are furthermore detailed in subclauses 1.1 (and 1.2) of the enclosed CCSDS publication.
