Description
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.
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.

Note: This is an interval method. See the Interval Methods page for more information.
Note: This method has a state. See the Methods and Properties with State page for more information.

Valid Range: |
-360 ≤ interferenceAngle ≤ 360 |
interferingSpacecraft |

Description: |
The interfering Spacecraft(s). |

1 to 30 times |
Return Value
Type: |
string |
Returns a formatted string which includes the start time, end time, and duration when a GroundStation tracking a Spacecraft is interfered with by a Star, Celestial Object, or another Spacecraft.
The FF_Preferences.IntervalEventReportingBehavior property controls whether the start and end of propagation are reported as events. By default, if the interference starts before the beginning of the propagation span, FreeFlyer will label the start of the propagation as the start of the interference. If the interference extends past the end of the propagation span, FreeFlyer labels the end of propagation as the end of the interference.
