Spacecraft.OrbitWizardSunSyncSetup(Variable, TimeSpan, Variable, String, Variable) Method

Top

Description

Initializes the state of a Spacecraft with a sun-synchronous orbit around the Earth. The user specifies the desired eccentricity and semi-major axis or inclination, and whether these are evaluated at the ascending or descending node. The Spacecraft's previous Argument of Perigee and True Anomaly are maintained.

Arguments

setupOption

Description:

Specify whether to define Semi-Major Axis or Inclination, and whether to use Ascending or Descending Node

Valid Values:

Value	Label
1	Define SMA, Calculate Inclination. Evaluate MLT at Ascending Node
2	Define SMA, Calculate Inclination. Evaluate MLT at Descending Node
3	Define Inclination, Calculate SMA. Evaluate MLT at Ascending Node
4	Define Inclination, Calculate SMA. Evaluate MLT at Descending Node

epoch
Description:	Epoch of the orbit state.

eccentricity
Description:	Eccentricity of the orbit.
Valid Range:	0 ≤ eccentricity ≤ 1

mltOfAscendingOrDescendingNode
Description:	Mean Local Time at the Node Crossing in the format hh:mm:ss.

semiMajorAxisOrInclination
Description:	Semi-Major axis or Inclination of the orbit.
Valid Range:	semiMajorAxisOrInclination ≥ 0

Return Value

Type:

number

Returns a 1 if the sun-synchronous orbit was initialized successfully. Returns a 0 if orbit initialization failed.
