Sandbox Error when simulating Nav Measurements using a Thrust History File

    Details

      Description

      See attached script (adapted from DJC unit tests) that simulates and estimates while using a thrust history file.

      The following steps cause an error:
      (1) Run attached script using the script "Save, Sync, Run" button.
      (2) After the first iteration residual plots show up (with data shown), stop the run using the Red square Stop Button.
      (3) Run script again using the script "Save, Sync, Run" button.

      The following error occurs:

      GmatBase Exception Thrown: GmatBase::GetParameterID() The object named "" of type "CoordinateSystemFixed" has no parameter defined with "Thruster1_SetPoint1_Est.ThrustScaleFactor"
      Sandbox Exception: Errors were found in the mission control sequence; please correct the errors listed in the message window
      *** Mission run failed.
      

      Secondary Question: See the attached PNG document of initial iteration residuals. The GDS residual look correct. What caused the CAN and MAD residuals to be so large?

      Build used is GMAT-R2015a-TSF_Solve_For_Build-x86.zip delivered 9/22/2016.
