Satellite: Astrogator Maneuver Ephemeris Block Initial: Spherical Elems

Name	Dimension	Type	Description
Time	DateFormat	Real Number	Time.
Cosine_of_Vertical_FPA	Unitless	Real Number	The dot product of the unit position and unit velocity vectors. The Calc Object allows a choice of a central body. The default is Earth.
Declination	AngleUnit	Real Number	The signed angle measured from the XY plane to the position vector, where positive angles are used for locations above the XY plane, and negative for those below.
Declination_Rate	AngleRateUnit	Real Number	The rate of change in the declination
Flight_Path_Angle	AngleUnit	Real Number	The angle between the position and velocity vectors. The Calc Object allows a choice of coordinate systems. The default is Earth Centered Inertial.
R_Mag	DistanceUnit	Real Number	The magnitude of the position vector (i.e. the radius vector). The Calc Object allows a choice of coordinate systems. The default is Earth Centered Inertial.
Right_Asc	AngleUnit	Real Number	The signed angle measured from the X axis to the projection of the position vector into the XY plane. The angle increases in the direction found by the right hand rule about the Z axis. The Calc Object allows a choice of coordinate systems. The default is Earth Centered Inertial.
Right_Asc_Rate	AngleRateUnit	Real Number	Right Ascension Rate
V_Mag	Rate	Real Number	The magnitude of the velocity vector, as observed in the coordinate system. The Calc Object allows a choice of coordinate systems. The default is Earth Centered Inertial.
Velocity_Azimuth	AngleUnit	Real Number	The angle, measured in the plane perpendicular to the position vector, between the local north direction and the projection of the velocity vector onto that plane, measured as positive moving toward local east. The Calc Object allows a choice of coordinate systems. The default is Earth Centered Inertial.
