Issues Addressed in FreeFlyer 7.6.1


Behavior Improvements

Added the ability for users to select license tier and packs when registering a network license via ff.exe using the License Server Feature Selection command line switch

Adjusted the way FreeFlyer interprets TimeSpans in certain file formats, specifically the FreeFlyer Ephemeris v3 and JSON files

oIf TimeSpan values are not specified to full nanosecond precision (9 digits after the decimal place), FreeFlyer will now implicitly right-pad the time value with zeros when reading the value

 

Error Cases

Optimization

Fixed a crash that would occur when the Optimizer.UpdateStateVariables() method was called before the Optimizer.LoadEngine() method

Fixed the optimizer's behavior to always store the first feasible solution as the best solution until an improved solution is found

Fixed the Optimizer.OptimizationPhase property to update when the Optimizer.UpdateStateVariables() method is called

Fixed optimizer state variable and constraint bounds to only be scaled when they have been changed from the default bounds

 

Orbit Determination

Fixed cases where Azimuth and Elevation measurements from a lunar GroundStation were processed incorrectly

 

Spacecraft Propagation

Fixed rare edge case issues with reading and writing attitude history files that also contain mass

Fixed an issue caused by the internal cache not being cleared after Ephemeris vector data is modified manually by the user

Fixed unexpected rotations in some configurations when propagating a direction cosine matrix (DCM)

Fixed CCSDS OEM Ephemeris files failing to write MetaData and EphemerisData comments

Fixed an error that was reported when modeling SRP in a Spacecraft's ForceModel if that Spacecraft's central body is a custom CelestialObject using a SPICE ephemeris for propagation

 

Generating Output

Fixed cases where the second PlotScatterSeries in a polar plot always drawn mirrored

Fixed the polar plot object to draw the radial axis correctly when the Theta axis is reversed

Fixed manually edited PlotScatterSeries points being reverted to the default point style

Fixed a crash which occurred occasionally when copying a matrix of data from a DataTableWindow

Fixed a crash that could occur in some edge cases when replaying a long Mission Plan

Fixed an issue where some components were not rendered in extremely complex 3D models

 

Command Line Interfaces

Fixed the Delete Configuration Files command line switch to delete all files with a single user access control request

Fixed a counting issue with the Profiler involving Procedures
