This attribute sets the values for Equinoctial elements used to define the spacecraft's Initial State.
Astrogator <Satellite Object Path> SetValue <Astrogator Object Path>.Equinoctial.{Attribute} <Value> [{Unit}]
If you select Equinoctial as the Coordinate Type, the following attributes can be specified:
| Attribute | Connect Name |
|---|---|
| Element type for Size | SizeType |
| Semi-major Axis | sma |
| Mean Motion | MeanMotion |
| h | h |
| k | k |
| p | p |
| q | q |
| Mean Longitude | MeanLongitude |
| Formulation | Posigrade, Retrograde |
Connect Name is used to set the value of an element while Attribute is used to select the element using an element type attribute.
You can use the SizeType attribute to set the element type to use for the Equinoctial size element or you can simply set a value for the desired element type and it will be selected automatically. For example, if Mean Motion is selected as the size element type and you send a command that sets the value for Semi-major Axis to 7,000 km, the type will be changed to Semi-major Axis.
