## CartesianOnePointPropagatorPropagate Method (JulianDate, JulianDate, Duration, Int32, ReferenceFrame, ITrackCalculationProgress) |

Calculates position (and zero or more derivatives) for regular time steps over an interval.

Note: when evaluating with this evaluator, it may be more efficient to specify times using an arithmetically safe TimeStandard 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.

Syntax

public DateMotionCollection<Cartesian> Propagate( JulianDate startDate, JulianDate stopDate, Duration timeStep, int order, ReferenceFrame outputReferenceFrame, ITrackCalculationProgress tracker )

- startDate
- Type: AGI.Foundation.TimeJulianDate

The first date for which to calculate position and velocity. - stopDate
- Type: AGI.Foundation.TimeJulianDate

The last date for which to calculate position and velocity. - timeStep
- Type: AGI.Foundation.TimeDuration

The Duration between each ephemeris point. - order
- Type: SystemInt32

The order of the highest derivative to compute. To compute just position, pass 0. To compute position and velocity (if available), pass 1. And so on. - outputReferenceFrame
- Type: AGI.Foundation.GeometryReferenceFrame

The reference frame in which the generated ephemeris data is to be expressed. - tracker
- Type: AGI.FoundationITrackCalculationProgress

The object to which progress is reported and that is able to cancel this operation before it is complete.

A list of date and motion for each step in the interval. The stopDate is always the last point in the list even when this makes the step between the second-to-last and last points less than the specified step.

Remarks

This method takes advantage of the ThreadingPolicy
to improve performance.
