It looks like your int_constr.cdx file needs an update. I have attached the latest version: (See attached file: int_constr.cdx) Could you please replace the file in your "OPS SERVER FDS DATA DIRECTORY" and run the IFDSOC.bin test again? Thanks Frank From - Wed Jun 16 14:30:04 2004 From: Frank.Dreger@esa.int To: John Treloar cc: pbarr@rssd.esa.int Subject: Re: [Fwd: Re: Moon Constraint Violation etc.....] Hi John, that is good enough for Paul to re-plan 207. You may want to update the eclipse file for good measure: (See attached file: eclip) Kind regards Frank v2.2i_1 (ISOC 10.4.3) --------------------- 15/06/04 11:15 From: Frank Dreger To: Lars Hansson/estec/ESA@ESA, jnolan@rssd.esa.int@ESA, JohnTreloar/estec/ESA@ESA Subject: Moon Constraint Violation during eclipse for pointing 02070059 (0207_05.POS) Dear colleagues, we have detected a moon constraint violation for the target attitude of pointing 02070059 in POS version 5 for revolution 207. The reason why your scheduling system did not flag this violation is (most likely) due to an out dated version of the eclipse season files used by the constraint checking and slew time prediction software. The files in question are located in the CCHK data directory (environment variable: CCHK_DATA_DIR). Please find attached the updated files: These files should be placed in the above mentioned directory to replace the files currently present. The permissions should be as follows: ls -l int_constraint_offsets* -rw-r--r-- 1 intatt integral 1024 May 13 09:59 int_constraint_offsets.dat -rw-r--r-- 1 intatt integral 4096 May 13 09:59 int_constraint_offsets.idx -rw-r--r-- 1 intatt integral 280 Jun 12 2001 int_constraint_offsets.isdb Once this upgrade is completed the POS for rev 207 (and possibly future revolutions) need to be generated. Pleas except my apologies for the inconvenience caused. Kind regards Frank v2.2i (ISOC 9.7.4) ------------------ Fixed SPRs :- 510 STPS crashes during close-loop slew
