The results from line_6: the analysis will be used to update the PDB and the flight software, and are line_7: necessary for future observations ! ! end of abstract general_form_proposers: lname: RUMPL fname: W. inst: COMPUTER SCIENCES CORPORATION country: USA ! lname: FALLON fname: L. inst: COMPUTER SCIENCES CORPORATION country: USA ! lname: ABSHIRE fname: G. inst: COMPUTER SCIENCES CORPORATION country: USA ! lname: DAVENPORT fname: P. inst: GODDARD SPACE FLIGHT CENTER country: USA ! lname: VANLANDINGHAM fname: F. inst: COMPUTER SCIENCES CORPORATION country: USA ! ! end of general_form_proposers block general_form_text: question: 2 section: 1 line_1: This activity is a required step in the determination of the alignment and line_2: calibration parameters necessary for the proper processing of attitude sensor line_3: data in the onboard Pointing Control Systems and in the ground PASS attitude line_4: determination software. ! question: 3 section: 1 line_1: line_2: Each of the 90 degree slew maneuvers required in performing this calibration line_3: will cause the generation of an autonomous delayed FHST 3-axis attitude update. line_4: In the following description, positive roll, pitch, and yaw are defined as line_5: positive rotations. (right-hand coordinate system) around the +V1, +V2, and +V3 line_6: axes, respectively. RGA data is required from the start of the FHST data, or line_7: FHST plus FGS data, taken preceding a maneuver, during the maneuver, and line_8: through the data take following a maneuver. The uninterrupted sequence of line_9: observations consisting of FHST/FGS observations before and after a maneuver, line_10: as well as during the large angle maneuver, constitute a basic scheduling unit. line_11: The RGA data takes during any of the 90D maneuvers specified do not have to be line_12: interrupted because of occultations or SAA passages. However, the FGS and/or line_13: FHST data takes that follow the maneuver should be initiated immediately upon line_14: completion of any of these maneuvers, and the maneuver should commence line_15: immediately upon completion of the FGS and/or FHST data takes that precede the line_16: maneuver. Real-time downlinks are preferred for all data takes; however, data line_17: takes must be backed up to the ETR. ! question: 3 section: 2 line_1: The maneuvers described in this proposal are in two groups. After the line_2: first group of maneuvers is performed, the PASS shall require six hours to line_3: process the data. The FGS/RGA scale-factor-alignment matrices are then line_4: uplinked. A second group of maneuvers is then performed. The results of the line_5: processing of the data obtained from the second group of maneuvers will be line_6: available on the PASS data bases six hours after the receipt of the data line_7: associated with all the maneuvers in the second group. The maneuvers in each line_8: group are described in the following paragraphs. No preferred sequence of line_9: performing the maneuvers within either group is required. ! question: 3 section: 3 line_1: The maneuvers within the first group are described as follows. The HST line_2: will be maneuvered to point the -V1 axis toward the sun, and the +V3 axis at line_3: the North Ecliptic Pole. After obtaining data from at least two simultaneously line_4: unocculted FHSTs for at least five minutes, the HST will be rolled +90D. Data line_5: from at least two simultaneously unocculted FHSTs will be taken for at least line_6: five minutes immediately after the end of this maneuver. Each of the four line_7: remaining maneuvers is performed by maneuvering between two of the following line_8: targets: Target 1 is the first ecliptic field west of the anti-sun; Target 2 is line_9: the ecliptic field approximately 90 degrees west of Target 1; Target 3 is the line_10: North Ecliptic Pole field. The required maneuvers are: (1) a -90D pitch from line_11: Target 1 to Target 2; (2) a +90D yaw from Target 2 to Target 3 ; (3) a -90D yaw line_12: from Target 3 to Target 2; and (4) a +90D pitch from Target 2 to Target 1. line_13: Immediately preceding and immediately following each of the 90D maneuvers line_14: described, the FGSs should acquire guide stars for the appropriate field and line_15: observe the guide stars for a minimum of three minutes. Data from at least one line_16: unocculted FHST must be taken in parallel with the FGS guide star data acquired line_17: immediately before and after each maneuver; however, data from more than one line_18: unocculted FHST is preferred. ! question: 3 section: 4 line_1: The maneuvers within the second group are described as follows. The line_2: requirements stated above for collecting RGA, FHST, and FHST and FGS data also line_3: pertain to the maneuvers in this group. Target 4 is defined to be the South line_4: Ecliptic Pole field. The required maneuvers are: (1) a -90D pitch from Target 1 line_5: to Target 2 ; (2) a -90D yaw from Target 2 to Target 4 ; (3) a +90D yaw from line_6: Target 4 to Target 2 ; and (4) a +90D pitch from Target 2 to Target 1. line_7: (Simultaneous FGS data and FHST data are required before and after each of the line_8: preceding maneuvers.) For the fifth maneuver in this group, the HST +V1 axis is line_9: pointed to the anti-sun with the +V3 axis in the ecliptic plane and positioned line_10: west of the anti-sun. The HST is than rolled -90D (only FHST data are required line_11: before and after this maneuver). line_13: Based on studies the proposers have made of the geometrical patterns line_14: associated with the scheduling of this proposal, the observations as specified line_15: in the Exposure Logsheet may not be obtainable. Therefore, in order to obtain line_16: the best observational results, the following directives should be understood line_17: and followed. ! question: 3 section: 5 line_1: The basic sheduling unit should be maintained. However, geometrical line_2: considerations may not allow the FHST observations to be scheduled for line_3: all pitch and yaw maneuvers. Therefore, the positive and negative pitch and yaw line_4: maneuvers should be scheduled as follows. Either the positive or the negative line_5: maneuver should be scheduled according to the requirements of the basic line_6: scheduling unit. The opposite maneuver (i.e., the negative maneuver if the line_7: positive maneuver was scheduled as above, or the positive maneuver if the line_8: negative maneuver was scheduled as above) should be scheduled to provide the line_9: most star observations within the confines of the non-interruptable line_10: requirement. Acquiring the FGS data before and after the pitch and yaw line_11: maneuvers is mandatory. line_12: Preceding the first maneuver of the first group, the HST is maneuvered so line_13: that the +V3 axis is in the ecliptic plane west of the anti-sun, and the +V1 line_14: axis is pointed at the ecliptic field whose RA is less than or equal to the RA line_15: of the anti-sun. Once at this position, the FGS should acquire guide stars. FGS line_16: guide star data and RGA data are to be collected for one orbit. The PASS will line_17: compute RGA low mode drift rates based on FGS attitudes with these data. The line_18: results should be available on the PASS data bases 4.5 hours after the line_19: completion of the data take. ! question: 4 section: 1 line_1: N/A ! question: 5 section: 0 line_1: Real-time downlinks are preferred for all data takes; however, all data line_2: takes must be backed up to the ETR. line_3: The telemetry format should be the PN (32 kbps) format starting and ending with line_4: the guide star or FHST data obtained before and after each maneuver. The format line_5: for the FGS/RGA low mode drift rate should be PN (32 kbps). At other times the line_6: telemetry format should be the AN (4 kbps) format. This proposal specifically line_7: requests an ETR dump following each maneuver group. The proposers anticipate line_8: that more frequent ETR dumps will be performed within each group according to line_9: the ETR dump policy developed for orbital verification. line_10: The uninterrupted sequence of observations consisting of FHST/FGS line_11: observations before and after a maneuver, as well as RGA data during the line_12: large-angle maneuver, constitute a basic scheduling unit. The basic scheduling line_13: unit should be maintained. However, geometrical considerations may not allow line_14: the FHST observations to be scheduled for all pitch and yaw maneuvers. line_15: Therefore, the positive and negative pitch and yaw maneuvers should be line_16: scheduled as follows. Either the positive or the negative maneuver should be line_17: scheduled according to the requirements of the basic sheduling unit. The line_18: opposite maneuver (i.e., the negative maneuver if the positive maneuver was line_19: scheduled as above, or the positive maneuver if the negative maneuver was line_20: scheduled as above) should be scheduled to provide the most star observations line_21: within the confines of the non-interruptable requirement. Acquiring the FGS line_22: data before and after the pitch and yaw maneuvers is mandatory. ! question: 7 section: 1 line_1: The data reduction will be performed in the PASS system. The initial FGS/RGA line_2: scale-factor-alignment matrices are expected to be available on the PASS data line_3: bases about 6 hours after the receipt of the data associated with all the line_4: maneuvers in the first group. The corresponding results for the second line_5: sequence should be available on the PASS data bases about 6 hours after the line_6: receipt of the data associated with all the maneuvers in the second group. ! question: 8 section: 1 line_1: Prior to this activity, Bootstrap Phase A (Proposal #1539) must be completed. line_2: Bootstrap Phase A should result in the ability to achieve FGS Fine Lock with line_3: 2/3 aperture. Following this activity, Bootstrap Phase B (Proposal #2148) shall line_4: begin. ! !end of general form text general_form_address: lname: DAVENPORT fname: PAUL category: PI inst: GODDARD SPACE FLIGHT CENTER addr_1: MAIL CODE 514, BLDG. 3/229 city: GREENBELT state: MD zip: 20771 country: USA phone: (301) 344-5563 ! lname: VANLANDINGHAM fname: FRANK inst: COMPUTER SCIENCES CORP. addr_1: 4600 POWDER MILL RD. addr_2: PASS PROJECT city: BELTSVILLE state: MD zip: 20705 country: USA phone: (301) 937-0760 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: ANEP descr_1: NORTH ECLIPTIC POLE FIELD pos_1: RA = 18H 02M 20.68S +/-.2M, pos_2: DEC = 66D 33' 15.17" +/-1.5' equinox: 2000.0 pos_epoch_yr: 2000.00 ! targnum: 2 name_1: ASEP descr_1: SOUTH ECLIPTIC POLE FIELD pos_1: RA = 05H 57M 51.41S +/-.2M, pos_2: DEC =-64D 29' 09.47" +/-1.5' equinox: ^ pos_epoch_yr: 2000.00 ! targnum: 3 name_1: ECL1 descr_1: ECLIPTIC FIELD 1 pos_1: RA = 00H 01M 26.35S +/-.1M, pos_2: DEC = 00D 22' 27.58" +/-1.5' equinox: ^ pos_epoch_yr: 2000.00 ! targnum: 4 name_1: ECL2 descr_1: ECLIPTIC FIELD 2 pos_1: RA = 02H 05M 13.65S +/-.1M, pos_2: DEC = 14D 44' 15.90" +/-1.5' equinox: ^ pos_epoch_yr: 2000.00 ! targnum: 5 name_1: ECL3 descr_1: ECLIPTIC FIELD 3 pos_1: RA = 4H 4M 15.18S +/-.15M, pos_2: DEC = 25D 06' 20.30" +/-1.5' equinox: ^ pos_epoch_yr: 2000.00 ! targnum: 6 name_1: ECL4 descr_1: ECLIPTIC FIELD 4 pos_1: RA = 6H 02M 17.13S +/-.15M, pos_2: DEC = 23D 18' 43.9" +/-1.5' equinox: ^ pos_epoch_yr: 2000.00 ! targnum: 7 name_1: ECL5 descr_1: ECLIPTIC FIELD 5 pos_1: RA = 8H 11M 47.23S +/-.15M, pos_2: DEC = 20D 07' 28.7" +/-1.5' equinox: ^ pos_epoch_yr: 2000.00 ! targnum: 8 name_1: ECL6 descr_1: ECLIPTIC FIELD 6 pos_1: RA = 10H 11M 56.71S +/-.15M, pos_2: DEC = 11D 11' 49.60" +/-1.5' equinox: ^ pos_epoch_yr: 2000.00 ! targnum: 9 name_1: ECL7 descr_1: ECLIPTIC FIELD 7 pos_1: RA= 11H 59M 40.05S +/-.15M, pos_2: DEC= 0D 28' 8.13" +/-1.5' equinox: ^ pos_epoch_yr: 2000.00 ! targnum: 10 name_1: ECL8 descr_1: ECLIPTIC FIELD 8 pos_1: RA = 14H 02M 46.83S +/-.1M, pos_2: DEC = -10D 09' 16.90" +/-1.5' equinox: ^ pos_epoch_yr: 2000.00 ! targnum: 11 name_1: ECL9 descr_1: ECLIPTIC FIELD 9 pos_1: RA = 15H 54M 26.38S +/-.15M, pos_2: DEC = -20D 25' 40.70" +/-1.5' equinox: ^ pos_epoch_yr: 2000.00 ! targnum: 12 name_1: ECL10 descr_1: ECLIPTIC FIELD 10 pos_1: RA = 17H 57M 49.43S +/- .15M, pos_2: DEC =-25D 55' 57.50" equinox: 2000.0 pos_epoch_yr: 2000.00 ! targnum: 13 name_1: ECL11 descr_1: ECLIPTIC FIELD 11 pos_1: RA = 20H 19M 27.71S +/-.15M, pos_2: DEC = -19D 42' 21.30" +/-1.5' equinox: ^ pos_epoch_yr: 2000.00 ! targnum: 14 name_1: ECL12 descr_1: ECLIPTIC FIELD 12 pos_1: RA = 22H 01M 56.55S +/-.1M, pos_2: DEC = -8D 53' 54.20" +/-1.5' equinox: ^ pos_epoch_yr: 2000.00 ! ! end of fixed targets solar_system_targets: targnum: 15 name_1: A-S descr_1: OTHER ANTI-SUN lev1_1: TARGET POSITION IS IN DIRECTION OF +V1 lev1_2: AXIS WHEN -V1 AXIS IS POINTED TO SUN. lev1_3: SUN AND HST POSITIONS FROM lev1_4: EPHEMERIDES. ! ! end of solar system targets !
