Space data and information transfer systems. Attitude data messages shop-only pass through some Units and1 Scope This International Standard specifies two standard message formats for use in transferring spacecraft attitude information between space agencies: the attitude parameter message (APM) and the attitude ephemeris message (AEM). Such exchanges are used for: preflight planning for tracking or attitude estimation support; scheduling attitude and data processing support; carrying out attitude operations; performing attitude comparisons; carrying out
