PropagatorSGP4Segment

class ansys.stk.core.stkobjects.PropagatorSGP4Segment

SGP4 propagator segment.

Overview

Properties

ssc_number	Catalog number of the spacecraft, if created by a 2-line element set.
revolution_number	Rev. Number. Dimensionless.
epoch	Universal date and time at which the specified orbit elements are true. Dimensionless.
inclination	Angle between the angular momentum vector (perpendicular to the plane of the orbit) and the inertial Z-axis. Uses Angle Dimension.
argument_of_periapsis	Angle from the ascending node to the eccentricity vector (lowest point of orbit) measured in the direction of the satellite’s motion. Uses Angle Dimension.
right_ascension_ascending_node	Angle from the inertial X-axis to the ascending node. Uses Angle Dimension.
eccentricity	Value between 1 and 0 representing the ellipticality of the orbit. Dimensionless.
mean_motion	A measure of the osculating period of the orbit, expressed as an angular rate. Uses AngleRate Dimension.
mean_anomaly	Angle from the eccentricity vector to a position vector where the satellite would be if it were always moving at its average angular rate. Uses Angle Dimension.
mean_motion_dot	First time derivative of mean motion. Dimensionless.
motion_dot_dot	Second time derivative of mean motion. Dimensionless.
bstar	Drag term for the satellite.
classification	One-letter classification indicator. U - Unclassified, C - Classified, S - Secret.
international_designator	International designation of the satellite.
switching_method	Method used to switch between element sets.
range	How far apart the satellites are when switching occurs.
switch_time	Get or set the time of the switch between one element set and a second set. Not used when the Switching Method is Disabled.
enabled	Enable/disable the segment.
