Spacecraft.InRange(PointGroup, ProximityZone) Method

Top

Description

Returns a value of 0 when the first point of the targetPointGroup is outside all the specified rangeDefinitionProximityZone on the calling Spacecraft, and returns a value of 1 if the first point of the targetPointGroup is within the boundary of at least one ProximityZone. Only the first point in the PointGroup is used for this analysis. FreeFlyer uses a definitive analytical solution to evaluate this event.

Since the evaluation is instantaneous, care must be taken to adjust the propagator step size such that events of interest aren't skipped over.
