Description

The Differential Corrector profile targets specific values, defined as independent variables. The target sequence will change the value of independent variables as needed to achieve the goal defined by the dependent variables, using a differential correction algorithm (for more information see Astrogator - Technical Notes - Differential Corrector in the STK Help).

Examples

Setting the Targeter Mode

Available targeter modes are:

Iterate
Not Active
Run Once

Astrogator */Satellite/Satellite1 SetValue MainSequence.SegmentList.Target_Sequence.Profiles.Differential_Corrector.Mode Iterate

Variables

Control Parameters (Independent Variables)

Note: If an element of a linked component is selected as an independent variable, the changed value that is produced will only be applied to subsequent segments nested within the same target sequence. Segments that are outside of the target sequence will use the value that the element held at the beginning of the MCS. If you apply corrections after running the MCS, then on the next run, all segments within the MCS will use the value produced by the target sequence.

Setting Control Parameters to Active/Inactive

Targeter Color: Perturbations will be displayed in the trajectory color defined for the target sequence.

Astrogator */Satellite/Satellite1 SetValue MainSequence.SegmentList.Target_Sequence.Profiles.Differential_Corrector.PerturbationColor Targeter Color

Log

The Targeter Log contains a log of each iteration for previous runs of the differential corrector. The following information is on each listed run:

Run
Status
Iterations
Cost
Start Time
Elapsed Time

Cost is a simple cost function computed as the square root of the sum of the squares of the scaled differences between the achieved and desired values of the equality constraints (dependent variables).

This attribute retrieves the number of iterations of the last run.

Astrogator_RM */Satellite/Satellite1 GetValue MainSequence.SegmentList.Target_Sequence.Profiles.Differential_Corrector.NumIterations
