Configuration

Configuration overview

A few configuration parameters exist in CelestLab. They are used to set global properties such as how warning messages are handled or how the ECI frame is defined.

The configuration values are initially loaded from CelestLab configuration file: celestlab_config.txt located in SCIHOME if it exists and is valid, config_default.txt located in CelestLab home directory otherwise.

The parameter values can then be retrieved by CL_configGet and modified by CL_configSet.

To update the configuration file, see "Edit configuration file" in CelestLab menu.

Configuration parameters

The configuration options are the following:

• DISPLAY_MENU (not changeable*) :
  • yes : The CelestLab menu is displayed if Scilab is launched in 'standard' mode (default).
  • no : The CelestLab menu is not displayed.
• WARNING_MODE :
  • standard : Warning messages are printed in the console (default).
  • silent : Warning messages are not printed.
  • error : Warning messages are turned into error messages.
• VERBOSE_MODE :
  • standard : Additional messages are printed in the console (default).
  • silent : Additional messages are not printed.
• WARN_DEPRECATED :
  • yes : Deprecated functions warning messages are printed (once) in the console (default).
  • no : Deprecated functions warning messages are not printed.
• ECI_FRAME (not changeable*) :
  • CIRS : The ECI frame is CIRS, the ECF frame is TIRS (default).
  • Veis : The ECI frame is Veis, the ECF frame is PEF.
• TLE_WHICHCONST : Set of constants used by TLE functions
  • wgs72 : The set of constants used by TLE functions is consistent with wgs72 (default).
  • wgs72old : The set of constants used by TLE functions is consistent with wgs72 - older values.
  • wgs84 : The set of constants used by TLE functions is consistent with wgs84.
• TLE_OPSMODE : Mode of operation for TLE functions
  • afspc : Processing compatible with AFSPC (default).
  • impr : Improved processing (see Vallado code for details).
• STELA_WHICHCONST : Set of physical constants used by STELA orbit propagation model
  • CL : The constants used are the same as in CelestLab.
  • ST : The constants used are the ones defined in STELA's configuration directory (default).

*: not changeable by CL_configSet function.
