Larry Bracamante, through Sal Abbate and Aseel Anatawi, reports from Goldstone that the X-RCP HEMT power supply was replaced, correcting the problem. The DSS 26 data reported here are the first since that change was made, and we concur in his conclusion. The odd spectral characteristics are no longer present. The ingress measurement in today's health report shows the high-gain antenna rewind starting ~4 minutes before ingress (occultation 21183i, with start time 2003/338-11:13:00). We will continue collecting approximately one ingress per day to monitor the HGA rewind effects. The first measurement from DSS 26 on day 337/338 was lost due to a scripting error (occultation 21178e, with start time 2003/337-23:53:00). Only the first couple of measurements from DSS 43 on day 338 had weak +/-180, 300 Hz spurs (occultations 21182e and 21183e, with start times 2003/338-07:43:00 and 2003/338-09:41:00). The following occultations had small fluctuations in the free-space carrier amplitude: Occultation Start Date/Time DSS Comments ----------- ----------------- ----- -------------------------- 21174e 2003/337-16:01:00 63 ADC in 7 dB low first 3 min 21184e 2003/338-11:39:00 43 ADC in 5 dB low 21185e 2003/338-13:37:00 43 +/-1 dB random fluctuation 21187e 2003/338-17:32:00 54 +/-0.5 dB sin mod, T~30 s The following egress occultations had uplink ramp leakage: Occultation Start Date/Time DSS Comments ----------- ----------------- ----- -------------------------- 21170e 2003/337-08:10:00 43 only egress in pass 21175e 2003/337-17:59:00 63 1/2 egresses in pass 21183e 2003/338-09:41:00 43 with weak spurs 21184e 2003/338-11:39:00 43 with ADC in 5 dB low Closed Loop Data ================ Data Collection --------------- We have obtained the following files from OSCAR and EIS: Original File Name Name on SOPC ------------------------------------ ------------ ODF: 03337O338.DAT;1 3337338A.ODF TROPCAL: ATC03DEC.CSP;3 3335343A.TRO EOP: 031205-eop.long 20204057.EOP EOP: 031205-eop.short 30564057.EOP Ancillary Data ============== Data Collection --------------- We have obtained the following files from the DOM: Original File Name Name on SOPC ------------------------------------ ------------ OPT: optg_m_031204-040605_031205 3338157A.OPT SAK: mgs_solar_array_2003-337.ck 3337337A.SAK SCK: MGS_SCLKSCET.00052.tsc TSC00052.SCK SOE: mm325b.08.tsoe 3337346F.SOE SPK: spk_m_031204-040320_031205 3338080A.SPK SPK: spk_m_040320-040605_031205 4080157A.SPK TCK: mgs_spice_c_kernel_2003-337.ck 3337337A.TCK We have obtained the following files from NAIF: Original File Name Name on SOPC ------------------------------------ ------------ AGK: mgs_hga_ck_2003-11-25.bc 3329329A.AGK
