Issues Addressed in FreeFlyer 7.3.1


Orbit Determination

Added a SetAprioriCovariance method to all OD estimators to support assigning the covariance directly

 

Behavior Improvements

Fixed performance problems with Array.PushBack and similar methods in nanosecond timing precision mode

Fixed an error where a WhileStepping loop iteration could be skipped when called itself within another loop

Fixed a graphical error in GroundStation masks when switching between Viewpoint types

Fixed the behavior of TwoLineElement.WriteToFile() to correctly write all Spacecraft in a Formation and TLECatalog

Fixed an ambiguous error message that could be generated when using an improperly formatted UT1UTC.dat data file

Fixed the return value on BatchLeastSquaresOD.Iterate() to return 1 if it ran successfully

Fixed contact methods such as those on the VisibilitySegment object to allow changes to observer properties mid-analysis

Fixed boundary layer offset behavior in the case where the number of offset borders on each layer don't match

Fixed a parsing bug when concatenating multiple strings with double quotation marks in a Macro

Fixed percentage-based steering in the linear tangent steering mode to correctly handle the Maneuver start epoch

Fixed the output display appearing blank when reporting large Array objects of multiple hundred elements

Fixed a display issue with the StarMap Viewpoint and drawing Sensor swath history for very long tails

Fixed an error where you could change the default Star Field file even when it was set to use the default

Fixed the output for GraphicsOverlay objects with lines that wrap around the edge of a 2D Map Viewpoint

Fixed a case where a location layer could be added to a view but never actually show

Fixed the behavior of the output properties panel when windows are unconstrained from FreeFlyer

Fixed tooltips for Viewpoint descriptions to show up when using the GUI

Fixed tooltips for Mission View fields in User Preferences

 

Error Cases

Fixed a crash when calling FillLinspace on an empty Array

Fixed a crash when toggling drag estimation in the middle of a Kalman Filter's execution

Fixed a crash when using the Propagate Orbit Mission Plan Wizard

Fixed a crash when calling SingularValueDecomposition on an empty Matrix object

Fixed a crash with getting certain object types like the KalmanFilterOD object from a String

Fixed a crash when getting the position of an object in a RotatingPulsatingSystem without initializing it

Fixed a crash when registering an Extension that has a user-defined "Name" property

Fixed a crash when right-clicking on a UserInterface or the TrackingDataEditor

Fixed a crash with assigning more than 10 line layers to a CelestialObject within the Output Properties window

Fixed a crash when calling ViewWindow.GetConfiguration() on a ViewWindow that contains a Formation with ViewAsGroup set to 0

Fixed a crash that could sometimes happen when opening the Spacecraft object panel

Fixed a crash when clicking on a group node in the view properties window if it contains objects with different ViewFont settings
