Spherical Elements components are a subset of Calculation Object components.

Syntax

ComponentBrowser */ SetValue "Calculation Objects" {Component} {Attribute} <Value> [{Unit}]

ComponentBrowser */ Duplicate "Calculation Objects" {Component} <Duplicate Component Name>

Description

The Spherical Elements components are:

Component Description
Cosine of Vertical FPA The cosine of the vertical flight path angle
Declination Declination
Declination Rate Declination Rate
Flight Path Angle Horizontal Flight Path Angle
R Mag Magnitude of position vector
Right Asc Right Ascension
Right Asc Rate Right Ascension Rate
V Mag Magnitude of velocity vector
Velocity Azimuth Velocity Azimuth

The attributes for each component have the same names and value selections that appear in the Astrogator graphical user interface.

Examples

Duplicating a Spherical Elements component

ComponentBrowser */ Duplicate "Calculation Objects" "Flight Path Angle" "My Flight Path Angle"

Changing the coordinate system of a Velocity Azimuth component

ComponentBrowser */ SetValue "Calculation Objects" "My Velocity Azimuth" CoordSystem "CentralBody/Earth J2000"

Changing the reference point of an R Mag component

ComponentBrowser */ SetValue "Calculation Objects" "My R Mag" ReferencePoint "CentralBody/Earth L1"
