Real Number |
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. |
