UsafGeneralPerturbationElements Properties

Gets or sets the argument of perigee, in degrees.

Gets or sets the ballistic coefficient or the area times the drag coefficient divided by the mass. This value has the units of m^2/kg.

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 classification.

Gets or sets the eccentricity

Gets or sets the element number.

Gets or sets the energy dissipation rate of the satellite due to atmospheric drag in watts/kg.

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 UsafGeneralPerturbationElements has ephemeris type 4.

Gets or sets the epoch at which these initial conditions are defined.

Gets or sets the last calculated error growth rate in kilometers per day.

Gets or sets the inclination, in degrees

Gets or sets the international designator.

Gets or sets the time of last observation that was used by orbit determination for the satellite. This time is in +/- fractional days relative to the Epoch.

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 type of orbiting body.

Gets or sets the original satellite number of the object. This is often the same as the SatelliteNumber.

Gets or sets the median radar cross section of the object.

Gets or sets the epoch at which these initial conditions are defined, represented in the standard form: YYYYDDD.DDDD.

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 AGOM or the area times the solar radiation pressure coefficient (gamma) divided by the mass. This value has the units of m^2/kg.

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

Gets or sets the median visual magnitude of the object scaled to the standard distance of 35786 km (elevation of GEO at zenith). This value is used regardless of the sensor to satellite geometry.
