GroundStation.TrackingInterference Method

Top 

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.
