Sgp4PropagatorGetEvaluator Method (EvaluatorGroup)

Gets an evaluator that can propagate at individual dates.

This evaluator propagates the orbit state from InitialConditions around the Earth. The result of evaluating will be the Motion<Cartesian> corresponding to the orbital position and velocity at the given JulianDate expressed in the EarthCentralBody's TrueEquatorMeanEquinoxFrame.

*Note* When evaluating with this evaluator, it will be more efficient to specify times using the TAI time standard to avoid the need to convert in order to perform the propagation. The length of a time step may be different in different TimeStandards. So be careful when specifying times.

Namespace:  AGI.Foundation.Propagators
Assembly:  AGI.Foundation.Models (in AGI.Foundation.Models.dll) Version: 24.3.420.0 (24.3.420.0)
Syntax
Copy
public override MotionEvaluator<Cartesian> GetEvaluator(
	EvaluatorGroup group
)

Parameters

group
Type: AGI.FoundationEvaluatorGroup
The group with which to associate the new evaluator. By grouping evaluators that are often evaluated at the same Julian dates, common computations can be performed only once for the entire group instead of multiple times for each evaluator.

Return Value

Type: MotionEvaluatorCartesian
The evaluator.
Exceptions
ExceptionCondition
ArgumentNullException Thrown when the group is .
