Configuration

This tab includes four kind of data.

Result type

The kind of computation is included in the following list:

• Reentry simulation : this mode is the most complete as it allows computing a reentry date after having estimated S/M and detecting maneuvers
• S/M estimation : this mode will estimate S/M and will detect maneuvers
• Manoeuvers detection : this mode will only detect maneuvers
• Manoeuvers Pdf report : this mode allows to create reports in Pdf format

End of History

This data corresponds to the most recent date where to find TLE. Be careful that, due to some tuning (see specific parameter here), if the last available TLE is too old by comparizon to this date, OPERA will exit in error status.

Duration

This data simply corresponds to the interval (in days) to consider TLE data.
