BS PD ISO/TR 19473:2015 provides the best practices for orbit elements at payload-LV separation. Itincludes orbit elements and calculation conditions, calculation method of orbit elements and theirerrors at elliptical orbit insertion of various payloads. The fit between the actual and expected values oforbit elements can be used as a criterion of commercial launch.There are many different sets of orbit elements. Each is best suited for a particular application. Thetraditionally used set of orbital elements is called the set of Keplerian elements. This Technical Reportgives the calculation method of Keplerian elements and the transformation method of all the other orbitelements, in order to satisfy different user's need.Affected by terrestrial gravitational perturbation, lunisolar gravitation perturbation and other factors,orbit elements change slowly after orbit injection. Orbit elements calculation methods after separationare not included in this Technical Report.The technical communication and specific progress for orbit elements is relatively easy to be agreed onby applying this Technical Report, which can contribute to avoiding possible disputes.Cross References:ISO/TR 11233ISO 14303CCSDS 500.0-G-3CCSDS 502.0-B-2CCSDS 503.0-B-1CCSDS 504.0-B-1ANSI/AIAA S-131-2010ISO 15863
