APPENDIX A - Classes
SEC 3D Location

Class Name: SEC 3D Location

Superclass - <Location 3D>

Subclasses

This DRM class is concrete and has no subclasses.

Definition

An instance of this DRM class specifies a coordinate for an SRF based on the Solar Ecliptic SRFT.

See 8.5.12 Solar ecliptic SRFT of ISO/IEC 18026 for a complete definition.

Primary Page in DRM Diagram:

Secondary Pages in DRM Diagram:

This class appears on only one page of the DRM class diagram.

Example

  1. SRFs derived from the Solar Ecliptic SRFT are convenient for representing such data as:

    1. interplanetary magnetic field observations;
    2. solar wind velocity data; and
    3. satellite trajectories.

FAQs

Is SEC an inertial coordinate system?

SEC is quasi-inertial in that it has a yearly rotation.

Where can users obtain further information on SEC?

See the SRM for additional details.
