The third measurement (8289i) was lost because the DSP went out of the link a few minutes before the measurement. The station rebooted the DSP, but I had problems loading the predicts. It wasn't a predicts problem. The station could not load the DSN predicts either. The script for the fourth measurement (8290i) ran, but the DSP did not go into record because no predicts could be loaded. The station reported that the DSP was having major problems, and that they will call maintenance to take a look at it. The Ops Chief (who was very helpful through all of this) has requested a DR to be open for loss of our data. I don't have a DR# yet. One more thing .. The Ops Chief mentioned that today's 10 pass that was originally schedule for DSS 25 will be switched to DSS 15 instead due to antenna problems . At least we have enough time to regenerate predicts and change the scripts before the measurements start! -Aseel -------------------------------------------------------------------------- From ppriest@airmail.fltops.jpl.nasa.gov Sun Jan 14 08:50 PST 2001 Received: from thorn.fltops.jpl.nasa.gov (thorn.fltops.jpl.nasa.gov [137.228.90.10]) by magellan.stanford.edu (8.9.3/8.9.3) with SMTP id IAA27492; Sun, 14 Jan 2001 08:50:35 -0800 (PST) Received: by thorn.fltops.jpl.nasa.gov; id IAA25031; Sun, 14 Jan 2001 08:50:55 -0800 Received: from airmail.fltops.jpl.nasa.gov(137.228.96.12) by thorn.fltops.jpl.nasa.gov via smap (V4.2) id xma024636; Sun, 14 Jan 01 08:50:11 -0800 Received: from mmrs.fltops.jpl.nasa.gov (mmrs.fltops.jpl.nasa.gov [137.228.136.10]) by airmail.fltops.jpl.nasa.gov (8.9.3+Sun/8.9.3) with ESMTP id IAA10152; Sun, 14 Jan 2001 08:50:10 -0800 (PST) Received: (from ppriest@localhost) by mmrs.fltops.jpl.nasa.gov (8.8.8+Sun/8.8.8) id QAA09128; Sun, 14 Jan 2001 16:50:10 GMT Date: Sun, 14 Jan 2001 16:50:10 GMT From: Patricia Priest Message-Id: <200101141650.QAA09128@mmrs.fltops.jpl.nasa.gov> DSS: 25 Apparently-To: Apparently-To: Content-Type: text Content-Length: 437 Status: RO Orbit: 8291i SOE: mm105a.04.tsoe Begin Record: 014/12:25:00 End Record: 014/12:32:00 Last Attenuation Change: SNT: Elevation Angle: Orbit: 8292i SOE: mm105a.04.tsoe Begin Record: 014/14:23:00 End Record: 014/14:30:00 Last Attenuation Change: 014 SNT: Elevation Angle: Orbit: 8293i SOE: mm105a.04.tsoe Begin Record: 014/16:21:00 End Record: 014/16:28:00 Last Attenuation Change: SNT: Elevation Angle: -------------------------------------------------------------------------- From aseel@godzilla.jpl.nasa.gov Sun Jan 14 23:30 PST 2001 Received: from godzilla.jpl.nasa.gov (godzilla.jpl.nasa.gov [137.78.177.120]) by magellan.stanford.edu (8.9.3/8.9.3) with ESMTP id XAA23757 for ; Sun, 14 Jan 2001 23:30:41 -0800 (PST) Received: from localhost (localhost [127.0.0.1]) by godzilla.jpl.nasa.gov (8.9.3/8.9.3) with SMTP id XAA00879 for ; Sun, 14 Jan 2001 23:31:01 -0800 (PST) Message-Id: <200101150731.XAA00879@godzilla.jpl.nasa.gov> Date: Sun, 14 Jan 2001 23:31:01 -0800 (PST) From: Aseel Anabtawi Reply-To: Aseel Anabtawi Subject: 2001/015 at DSS 65 To: rsimpson@magellan.stanford.edu MIME-Version: 1.0 Content-MD5: cyjcSunuZ1WMaRzLfTuZ2A== X-Mailer: dtmail 1.2.1 CDE Version 1.2.1 SunOS 5.6 sun4u sparc Content-Type: TEXT/plain; charset=us-ascii Content-Length: 162 Status: R Hi, All measurements were lost because the DSP is still red (DR#L04987).

I was more concerned about generating predicts and changing the scripts, and by the time I remembered, the notifications had already gone out. About the signal disappearing at approx. ingress .. I was looking at the LMC log, and I saw a note about circular buffer errors. I checked the radsci10 log, and there was an "out of circular buffer error" at 16:26:13. The time for "enter earth occultation" in the SOE is 16:25:59, so it's pretty close! This might be the cause. I'm sorry I would've mentioned this to you earlier, but I wasn't aware of it. There was one error message only. When it is a serious problem, we usually get scrolling errors. I doubt the person monitoring the pass could've done anything to save this measurement. The error was too close to ingress, and probably by the time he saw it, the signal had already disappeared. > I may not do any processing today; it is a holiday at Stanford. Wow! A day off!!

The nice thing is that you have the ability to sift back through the LMC loog to try to make sense of the error. An error even minutes before occultation would be almost impossible to correct; seconds is out of the question. Thanks to you and the others for being there to do the preventive maintenance first and the error reporting later. -------------------------------------------------------------------------- From joe@neptune.stanford.edu Wed Jan 31 14:09 PST 2001 Received: from neptune.Stanford.EDU (neptune [171.64.90.149]) by magellan.stanford.edu (8.9.3/8.9.3) with ESMTP id OAA11292 for ; Wed, 31 Jan 2001 14:09:18 -0800 (PST) Received: (from joe@localhost) by neptune.Stanford.EDU (8.9.3/8.9.3) id OAA16476; Wed, 31 Jan 2001 14:09:16 -0800 (PST) Message-ID: X-Mailer: XFMail 1.2 [p0] on Solaris X-Priority: 3 (Normal) Content-Transfer-Encoding: 8bit MIME-Version: 1.0 In-Reply-To: <200101312149.NAA08638@magellan.stanford.edu> Date: Wed, 31 Jan 2001 14:09:16 -0800 (PST) Sender: joe@neptune.stanford.edu From: Joe Twicken To: joe@nova.stanford.edu, rsimpson@magellan.stanford.edu, hinson@nova.stanford.edu Subject: RE: ODR Notice: /users/z05/procODR/10312134 Content-Type: text/plain; charset=us-ascii Content-Length: 965 Status: RO (1) There was no HGA motion compensation for these recordings On 31-Jan-01 Joe Twicken 723-3597 wrote: > 10140435.ODR p 65XRXIR1R201 65XRXIC1XX01 65XR1IF1S101 65XR1IS1T101 > 65XR1IS1T201 65XR1IS1T301 65XR1IS1T401 65XR1IS1T501 > 10140632.ODR p 65XRXIR1R201 65XRXIC1XX01 65XR1IF1S101 65XR1IS1T101 > 65XR1IS1T201 65XR1IS1T301 65XR1IS1T401 65XR1IS1T501 > 10141225.ODR p 15XRXIR1R201 15XRXIC1XX01 15XR1IF1S101 15XR1IS1T101 > 15XR1IS1T201 15XR1IS1T301 15XR1IS1T401 15XR1IS1T501 > 10141423.ODR p 15XRXIR1R201 15XRXIC1XX01 15XR1IF1S101 15XR1IS1T101 > 15XR1IS1T201 15XR1IS1T301 15XR1IS1T401 15XR1IS1T501 > 1014162B.ODR p 45XRXIR1R201 45XRXIC1XX01 45XR1IF1S101 45XR1IS1T101 > 45XR1IS1T201 45XR1IS1T301 45XR1IS1T401 45XR1IS1T501 > 10142016.ODR p 45XRXIR1R201 45XRXIC1XX01 45XR1IF1S101 45XR1IS1T101 > 45XR1IS1T201 45XR1IS1T301 45XR1IS1T401 45XR1IS1T501 > 10142214.ODR p 45XRXIR1R201 45XRXIC1XX01 45XR1IF1S101 45XR1IS1T101 > 45XR1IS1T201 45XR1IS1T301 45XR1IS1T401 45XR1IS1T501 -------------------------------------------------------------------------- From joe@neptune.stanford.edu Tue Nov 13 14:23 PST 2001 Received: from neptune.Stanford.EDU (neptune [171.64.90.149]) by magellan.stanford.edu (8.9.3/8.9.3) with ESMTP id OAA25821 for ; Tue, 13 Nov 2001 14:23:37 -0800 (PST) Received: (from joe@localhost) by neptune.Stanford.EDU (8.9.3/8.9.3) id OAA24710; Tue, 13 Nov 2001 14:20:34 -0800 (PST) Message-ID: X-Mailer: XFMail 1.2 [p0] on Solaris X-Priority: 3 (Normal) Content-Transfer-Encoding: 8bit MIME-Version: 1.0 In-Reply-To: <200111132157.NAA24989@magellan.stanford.edu> Date: Tue, 13 Nov 2001 14:20:34 -0800 (PST) Sender: joe@neptune.stanford.edu From: Joe Twicken To: joe@nova.stanford.edu, rsimpson@magellan.stanford.edu, hinson@nova.stanford.edu Subject: RE: ODR Notice: /users/z18/procODR/13172125 Content-Type: text/plain; charset=us-ascii Content-Length: 1016 Status: RO (1) Reprocessed with Goddard trajectory (2) There was no HGA motion compensation for the 10141423.ODR recording On 13-Nov-01 Joe Twicken 723-3597 wrote: > 10140435.ODR p 65XRXIR1R202 65XRXIC1XX02 65XR1IF1S102 65XR1IS1T102 > 65XR1IS1T202 65XR1IS1T302 65XR1IS1T402 65XR1IS1T502 > 10140632.ODR p 65XRXIR1R202 65XRXIC1XX02 65XR1IF1S102 65XR1IS1T102 > 65XR1IS1T202 65XR1IS1T302 65XR1IS1T402 65XR1IS1T502 > 10141225.ODR p 15XRXIR1R202 15XRXIC1XX02 15XR1IF1S102 15XR1IS1T102 > 15XR1IS1T202 15XR1IS1T302 15XR1IS1T402 15XR1IS1T502 > 10141423.ODR p 15XRXIR1R202 15XRXIC1XX02 15XR1IF1S102 15XR1IS1T102 > 15XR1IS1T202 15XR1IS1T302 15XR1IS1T402 15XR1IS1T502 > 1014162B.ODR p 45XRXIR1R202 45XRXIC1XX02 45XR1IF1S102 45XR1IS1T102 > 45XR1IS1T202 45XR1IS1T302 45XR1IS1T402 45XR1IS1T502 > 10142016.ODR p 45XRXIR1R202 45XRXIC1XX02 45XR1IF1S102 45XR1IS1T102 > 45XR1IS1T202 45XR1IS1T302 45XR1IS1T402 45XR1IS1T502 > 10142214.ODR p 45XRXIR1R202 45XRXIC1XX02 45XR1IF1S102 45XR1IS1T102 > 45XR1IS1T202 45XR1IS1T302 45XR1IS1T402 45XR1IS1T502
