Block 12 - Install new PCK/TPC

Description

New planetary constants, or an update RA and DEC of Bennu pole, rotation rate, etc.

Procedure if parameters change a small amount (<3 deg)

• Capture state of system by running RESIDUALS and make a copy somewhere for comparison
• Update INIT_LITHOS.TXT and make_sumfiles.txt with new PCK/TPC
• Run MAKE_SUMFILES Option 1 to update the NOMINALS
• Capture state of system by running RESIDUALS again... did the s/c move the amount you would expect?
• Run DYNAMICS to set the sigmas to their proper value
• Update INIT_LITHOS.TXT to turn off overlaps and limbs on the LMK solution (stereo only) WB=1 WO=0 WL=0 WR=0.
• PIC_WEIGHT = 1 0 1 1 0
• GEOMETRY 210-3-n-n
• Reset INIT_LITHOS.TXT initial values
• GEOMETRY 210-3-n-n
• Iterate

Procedure if parameters change a large amount (<10 deg)

Similar to above, but requires an additional step to make sure the NOMINALS move as far as they should.

• Capture state of system by running RESIDUALS and make a copy somewhere for comparison
• Update INIT_LITHOS.TXT and make_sumfiles.txt with new PCK/TPC
• Run MAKE_SUMFILES Option 1 to update the NOMINALS
• Capture state of system by running RESIDUALS again... did the s/c move the amount you would expect?
• Make sure the sigmas in NOMINALS are small so that the next step brings the SUMFILES close to the NOMIALS
• GEOMETRY 20-15-n-n
• Run DYNAMICS to set the sigmas to their proper value
• Update INIT_LITHOS.TXT to turn off overlaps and limbs on the LMK solution (stereo only) WB=1 WO=0 WL=0 WR=0.
• PIC_WEIGHT = 1 0 1 1 0
• GEOMETRY 210-3-n-n
• Reset INIT_LITHOS.TXT initial values
• GEOMETRY 210-3-n-n
• Iterate
