BeforeConditions

This attribute sets "before" stopping conditions. A "before" stopping condition is used to define a stopping condition that depends on two events.

Syntax

Astrogator <Satellite Object Path> SetValue <Attribute Path>.BeforeConditions <List of Before Conditions>

Astrogator <Satellite Object Path> SetValue <Attribute Path>.BeforeConditions.{Before Condition} <Value> [{Unit}]

Description

Define the "before" stopping conditions for a Propagate or Impulsive Maneuver segment of the Mission Control Sequence (MCS). Define it as you would a normal stopping condition. When the MCS is run, Astrogator will ignore the normal stopping conidition until the "before" stopping conditions defined for it are met. Astrogator will then interpolate backwards to the normal stopping condition just prior to the "before" stopping condition, and this will be defined as the point at which the normal stopping condition is satisfied.

Note: The backwards interpolation is subject to the Minimum Propagation Time; in other words, the backwards interpolation will be performed for at least that specified amount of time before Astrogator will check for satisfaction of the condition.
