Spacecraft.OrbitWizardSunSyncSetup(Variable, Variable, 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.

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:

Return Value

Type:

number

 

 

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