ISO/IEC 18026 - Annex E, ORM specifications

Annex E
(normative)

ORM specifications

E.1 Introduction

This annex presents the specification of the standardized ORMs and associated RTs. If two or more object-fixed ORMs for the same object are specified then one of the ORMs is designated as the reference ORM for that object. Table E.1 in E.2.1 lists the reference ORMs specified in this International Standard, ordered alphabetically by their label. ORM specifications are listed in tables in E.2.2 according to object categories (abstract, Earth, other planet, satellites, and Sun) and binding type (object-fixed or dynamic). Table E.2 provides a directory of these tables. Parameter values in the tables are specified by value or by reference. Parameters specified by reference use the terminology in the cited references. Those terms are enclosed in brackets ( { } ). Referenced values in length units other than meters are converted to metres to specify the corresponding RT parameter.

E.2.2 Standardized ORMs

The elements of an ORM specification are defined in Table 7.10. Table E.2 is a directory of standardized ORMs organized by category of ORM and type of object. The ORM entries in each table are ordered alphabetically by their label. The directory includes deprecated ORMs in Annex J. ORM specifications may include one or more RT specifications. The RT specifications associated with an ORM immediately follow the ORM Table entry. RT entries are have a blank table cell shaded grey to distinguish RT entires from ORM entries in the tables.
