Description: |
A String containing the name of the celestial object to use when looking for apoapsis. |
Return Value
Type: |
number |
Units: |
km |
Returns the point in the orbit where the Spacecraft is at its furthest distance from a Planet, Moon, or CelestialObject.
Syntax
Step mySpacecraft1 to ( mySpacecraft1.OrbitApoapsis(myString1)); |
The OrbitApoapsis method can be used to notify the user when the Spacecraft has reached the apoapsis of its orbit. The following example shows how you can determine if a Spacecraft is at the apoapsis of its orbit around Mars. Spacecraft1 is assumed to be in an orbit around Mars.
The first Report command will report a 0, provided the Spacecraft is not initialized at the apoapsis of its orbit. The second Report command will report a 1, signifying the spacecraft has reached apoapsis.
Note: This example only works with orbits that have an eccentricity larger than 0.0001. |
