Time. |
Apparent_Solar_Time |
AngleUnit |
Real Number |
Apparent solar time expressed as an angle. The Calc Object allows a choice of a central body. The default is Earth. |
Beta_Angle |
AngleUnit |
Real Number |
Not defined for this class of object. |
Earth_Mean_Solar_Time |
AngleUnit |
Real Number |
Apparent solar time modified for earth's equation of time, expressed as an angle. The Calc Object allows a choice of a central body. The default is Earth. |
Local_Apparent_Solar_Longitude |
AngleUnit |
Real Number |
Apparent solar longitude minus vehicle longitude. The
Calc Object allows a choice of a central body. The default is Earth. |
Longitude_of_Periapsis |
AngleUnit |
Real Number |
The sum of the right ascension of the ascending node and the argument of periapsis.
The
Calc Object allows a choice of element type (Osculating elements, Kozai-Izsak Mean elements,
Brouwer-Lyddane Mean elements using only short period terms, and Brouwer-Lyddane Mean elements
using both short and long period terms). The default is osculating.
The
Calc Object allows a choice of coordinate systems. The default is Earth Centered Inertial.

Orbit_State_Value |
DateFormat |
Real Number |
Computes the value of the specified Calc Object given the specified input values
of position and velocity |
SignedEccentricity |
Unitless |
Real Number |
The eccentricity multiplied by either 1.0 or -1.0. The value is positive if the mean anomaly is within pi/2
radians of the periapsis, else it is negative. The
Calc Object allows a choice of element type (Osculating elements, Kozai-Izsak Mean elements,
Brouwer-Lyddane Mean elements using only short period terms, and Brouwer-Lyddane Mean elements
using both short and long period terms). The default is osculating.
|
SignedInclination |
AngleUnit |
Real Number |
The inclination multiplied by either 1.0 or -1.0. The value is positive if the argument of latitude
is within pi/2 radians of the ascending node, else it is negative. The
Calc Object allows a choice of element type (Osculating elements, Kozai-Izsak Mean elements,
Brouwer-Lyddane Mean elements using only short period terms, and Brouwer-Lyddane Mean elements
using both short and long period terms). The default is osculating.
|
True_Longitude |
AngleUnit |
Real Number |
The sum of the right ascension of the ascending node, the argument of periapsis, and the true anomaly.
The
Calc Object allows a choice of element type (Osculating elements, Kozai-Izsak Mean elements,
Brouwer-Lyddane Mean elements using only short period terms, and Brouwer-Lyddane Mean elements
using both short and long period terms). The default is osculating.
The
Calc Object allows a choice of coordinate systems. The default is Earth Centered Inertial.
