Miscellaneous Calc Objects.

Name Dimension Type Description
Time DateFormat 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.
