Description
The PhaseControlModel object allows users access to setting the ControlType used by the TrajectoryPhase. FreeFlyer currently supports three control models: ballistic (no control), simple thruster, and ideal solar sail. All control models and their associated variables are formulated in ICRF.
Users cannot create instances of this type of object. However, users can access instances of this object type that have been created indirectly, for example as children of other objects. Users can also access any static properties and methods on this object type.

Timing Precision Mode
This page describes functionality in millisecond timing precision mode. Millisecond timing precision mode is deprecated and will be removed in a future release. We recommend that you migrate your Mission Plans to nanosecond timing precision mode.

Attributes

ControlType
|
The type of control used by the ControlModel. All control models and their associated variables are formulated in the ICRF.
Warning: assigning a new value to this property will erase the existing control variables in the TrajectoryPhase and replace them with default values for the chosen control type.

ShadowingBodies
|
The shadowing bodies used for the control model. TrajectoryPhase shadow calculations use a spherical body assumption and do not account for body flattening. When shadowing bodies are present and the 'ControlModel.ControlType' is set to 'SimpleThruster', a constraint will be applied that prevents the thrust when the path of the TrajectoryPhase is shadowed by at least one shadowing body. When shadowing bodies are present and the 'ControlModel.ControlType' property is set to 'IdealSolarSail', no thrust will be produced when the path of the TrajectoryPhase is shadowed by at least one shadowing body.

AddShadowingBody
|
Adds a shadowing body to the ControlModel. TrajectoryPhase shadow calculations use a spherical body assumption and do not account for body flattening. When shadowing bodies are present and the 'ControlModel.ControlType' is set to 'SimpleThruster', a constraint will be applied that prevents the thrust when the path of the TrajectoryPhase is shadowed by at least one shadowing body. When shadowing bodies are present and the 'ControlModel.ControlType' property is set to 'IdealSolarSail', no thrust will be produced when the path of the TrajectoryPhase is shadowed by at least one shadowing body.
