Description
Provides detailed information on the times when a GroundStation tracking a Spacecraft is interfered with by a Star, Celestial Object, or another Spacecraft. Interference occurs when the tracked Spacecraft is visible to the GroundStation, but an interfering object(s) lies within a user-specified cone about the GroundStation-to-Spacecraft vector.
FreeFlyer calculates interference based on the times when the center of the interfering object is within the cone. If you want to model a non-zero angular width for an interfering object, you can add half the angular width of that object (as seen from the GroundStation) to the desired interference half-angle to get the total cone half-angle.
Note: When more than one interfering object is specified, ALL of these objects (as opposed to ANY) must lie within the interference cone for the tracking to be considered interfered.
The TrackingInterference method will account for refraction if refraction modeling is turned on using the GroundStation.RefractionModelType property.
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.

Returns a formatted string which can be reported to an output file using the Report command. For each interference period, the report will include the start time, end time, and duration of the interference between the GroundStation and the trackedSpacecraft due to interferingSpacecraft.

Returns the number of elements that have been populated into the EventTime and EventType arrays. The arrays are populated with the time and type of interference events, where an event can be the start or end of an interference between the GroundStation and the trackedSpacecraft due to interferingSpacecraft.
