Sgp4Elements Properties 
The Sgp4Elements type exposes the following members.
Name  Description  

ArgumentOfPerigee 
Gets or sets the argument of perigee, in degrees.
 
BStar 
Gets or sets the BSTAR drag term, in units of 1 / EarthRadii.
This term represents a modification of the ballistic coefficient
(Coefficient of drag times area over mass). The value is modified
by one half atmospheric density and expressed in units of inverse
Earth radii. Source: https://celestrak.com/  
Eccentricity 
Gets or sets the eccentricity
 
Epoch 
Gets or sets the epoch at which these initial conditions are defined.
 
Inclination 
Gets or sets the inclination, in degrees
 
MeanAnomaly 
Gets or sets the mean anomaly, in degrees.
 
MeanMotion 
Gets or sets the mean motion, in revolutions per day.
 
RawEpoch 
Gets or sets the epoch at which these initial conditions are defined,
represented in the standard form: YYDDD.DDDD. Note: this will
be represented to as much precision as possible and will not reflect
the RawEpoch taken from a
TwoLineElementSet format. To represent the correct
precision for a TLE, use the TwoLineElementSet type instead.
 
RightAscensionOfAscendingNode 
Gets or sets the right ascension of the ascending node, in degrees
 
SwitchingMethod 
Gets or sets the method to use when switching between this element set and the following element set.
By default, this is Sgp4ElementsSwitchByEpoch.
