TwoLineElementSet Properties

Gets or sets the argument of perigee, in degrees.

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/

Gets or sets the checksum for line 1.

Gets or sets the checksum for line 2.

Gets or sets the classification.

Gets or sets the eccentricity

Gets or sets the element number

Gets or sets the ephemeris type. Ephemeris Type 0 is the correct type for Sgp4Propagator. Ephemeris type 4 is not supported by Sgp4Propagator, and it will throw an argument exception if a TwoLineElementSet has ephemeris type 4.

Gets or sets the epoch at which these initial conditions are defined. Note: The epoch will only be represented to the precision of the TwoLineElementSet format from the RawEpoch. For greater precision, use Sgp4Elements directly.

Gets or sets the inclination, in degrees

Gets or sets the international designator

Gets or sets the mean anomaly, in degrees.

Gets or sets the mean motion, in revolutions per day.

Gets or sets the first derivative of mean motion divided by two, in revolutions per day squared.

Gets or sets the second derivative of mean motion divided by six, in revolutions per day cubed.

Gets or sets the spacecraft name

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 only the precision of the TwoLineElementSet format. For greater precision, use Sgp4Elements directly.

Gets or sets the revolution number at epoch.

Gets or sets the right ascension of the ascending node, in degrees

Gets or sets the satellite number.

Gets or sets the method to use when switching between this element set and the following element set. By default, this is Sgp4ElementsSwitchByEpoch.
