See COM-based Plugin Scripts for instructions on the setup and use of plugin scripts.

STK Astrogator plugin scripts

Sample Files	Description
VBScript: VB_ForceModel_Eval.vbs MATLAB: Matlab_ForceModel_Eval.m	A force model plugin script that adds user-defined accelerations to the force model
VBScript: VB_EngineModel_SegStart.vbs	A custom engine model plugin script that stores time
VBScript: VB_EngineModel_Eval.vbs	A custom engine model plugin script that combined with the VB_EngineModel_SegStart script completes the definition of a custom engine model
VBScript: VB_CalcObjectReset.vbs	A custom calculation object plugin script
VBScript: VB_CalcObject.vbs MATLAB: Matlab_CalcObject_Eval.m Python: PY_CalcObject.py	A custom calculation object plugin script

Constraint plugin scripts

Sample Files	Description
VBScript: VB_Constraint.vbs MATLAB: Matlab_Constraint.m Python: PY_Constraint.py	A constraint plugin script that provides a method for adding nongeneric, customized constraints directly into visibility computations

STK Communications plugin scripts

Sample Files	Description
VBScript: VB_TransmitterModel.vbs MATLAB: Matlab_TransmitterModel.m	A custom transmitter model plugin script
VBScript: VB_ReceiverModel.vbs MATLAB: Matlab_ReceiverModel.m	A custom receiver model plugin script.
VBScript: VB_RainLossModel.vbs MATLAB: Matlab_RainLossModeModel.m	A custom rain loss model plugin script
VBScript: VB_GaussianAntennaGain.vbs MATLAB: Matlab_GaussianAntennaGain.m	A custom antenna plugin script; in this case, the antenna is Gaussian with a rectangular dish; gain and beamwidth vary as a function of satellite position
VBScript: VB_CommSysSatSelStrat.vbs MATLAB: Matlab_CommSysSatSelStrat.m	A custom satellite selection strategy plugin script for a communications interference model
VBScript: VB_CommConstraint.vbs MATLAB: Matlab_CommConstraint.m	A custom communications constraint plugin script for transmitters and receivers
VBScript: VB_AntMultiBeamSelStrat.vbs MATLAB: Matlab_AntMultiBeamSelStrat.m	A custom beam selection strategy plugin script for multibeam antennas
VBScript: VB_AbsorpModel.vbs MATLAB: Matlab_AbsorpModel.m	A custom absorption loss model plugin script
VBScript: VB_PhasedArrayAntGain.vbs MATLAB: Matlab_PhasedArrayAntGain.m	A custom antenna gain plugin that models the main beam boresight gain as a broadside (that is, zero scan angle) maximum gain value reduced by the cosine of the scan angle; off-boresight mainbeam gain and sidelobe structures not modeled
VB_DynamicModulator_CustomPSD.vbs Matlab_DynamicModulator_CustomPSD.m	A custom Power Spectral Density plugin script.
VB_DynamicModulator_IdealPSD.vbs Matlab_DynamicModulator_IdealPSD.m	A modulator plugin script that is used to dynamically change either a modulator or a particular encoding while allowing STK to compute a theoretical PSD
