This should be the last time, though. Due to MOLA ISH, the spacecraft did not go two-way between the MOLA ISH and the egress. Therefore, there is a full (and more) baseline for egress! For occultations 168-171, the spacecraft is occulted, but it goes through the atmosphere for an unusually long time (of course) since it is grazing. Due to the spacecraft configuration, MGS usually goes one-way in the middle of the atmosphere. The MOLA ISH may actually help us with a few egresses until the MOLA ISHs make egress measurements impossible. Hopefully, they will not be on top of egress for long.

Therefore, I propose to send a general occultation status to the larger group approximately once per day rather than an e-mail for every occultation. Please let me know if this is a problem. Occultation 171: Went well. At this grazing geometry, the atmosphere lasts longer than the 3 minutes 45 seconds of one-way. There is enough baseline for egress, however. Egress is followed by the MOLA ISH. The station does not have time to go two-way between egress and the MOLA ISH, so we collect one-way data. This is only beneficial until the MOLA ISH and egress overlap. Occultation 172: Unfortunately the station was having significant problems with their telemetry system (TGC). The station and the Ace were heavily involved in rectifying the situation, and the DSP was left out of the link. (They had to switch DSN tracking stations. It was messy. ) Occultation 173: Went well. There egress data should have plenty of baseline for the next several orbits. Occultation 174: A maneuver was performed at apoapsis -- on top of ingress. No data. The maneuver changed the trajectory and the predicts did not follow; therefore, the signal was not in the passband for egress. Once the occultation moves away from apoapsis, this will not be a problem. Until then, we need to find a solution for egress. Larger bandwidth? A different SPK file with the maneuver modeled better? I don't know if that exists. We also received the error message for the sawtooth during this recording period. Occultation 175: Went well. Nice baseline for egress. Occultation 176: Went well. Nice baseline for egress. -Trish ------------------------------------------------------------------------------ From trish@godzilla.jpl.nasa.gov Mon Nov 23 12:12:33 1998 Received: from godzilla.jpl.nasa.gov (godzilla.jpl.nasa.gov [137.78.177.120]) by magellan.Stanford.EDU (8.8.5/8.8.3) with ESMTP id MAA12850; Mon, 23 Nov 1998 12:12:32 -0800 (PST) Received: from rodan.jpl.nasa.gov (rodan.jpl.nasa.gov [137.78.177.110]) by godzilla.jpl.nasa.gov (8.8.8+Sun/8.8.5) with ESMTP id MAA25256; Mon, 23 Nov 1998 12:12:27 -0800 (PST) Received: from 137.78.177.117 (trish-mac.jpl.nasa.gov [137.78.177.117]) by rodan.jpl.nasa.gov (8.8.5/8.8.5) with SMTP id MAA27896; Mon, 23 Nov 1998 12:12:25 -0800 (PST) Message-Id: <199811232012.MAA27896@rodan.jpl.nasa.gov> Date: 23 Nov 98 12:18:44 -0800 From: Trish Priest Subject: FWD: Occ. 173 Orbit 746 To: Richard Simpson , Data Account Stanford , Joe Twicken X-Mailer: QuickMail Pro 1.0.2d1 X-Priority: 3 Reply-To: Trish Priest Content-Type: text/plain; charset="iso-8859-1" Content-Length: 316 Status: RO Year 1998 DOY 325 DSS 15 SOE a747a.01.tsoe Orbit: 746 Occultation: 173 Script File Name: 98.325.15.a746.scr Ground Mode: 1-way Time To Execute: 325/11:15 Begin Record: 325/12:06:00 End Record: 325/12:59:00 Last Attenuation Change: Final Attenuation Value: SNT: 30.37 AGC: -146.0 Elevation Angle: 32.979 ------------------------------------------------------------------------------ From joe@nova.Stanford.EDU Mon Nov 23 14:25:46 1998 Received: from nova.stanford.edu (nova.Stanford.EDU [36.10.0.123]) by magellan.Stanford.EDU (8.8.5/8.8.3) with ESMTP id OAA19321 for ; Mon, 23 Nov 1998 14:25:46 -0800 (PST) Received: from neptune.Stanford.EDU (neptune.Stanford.EDU [36.10.0.149]) by nova.stanford.edu (8.8.8/8.8.4) with ESMTP id OAA32133; Mon, 23 Nov 1998 14:25:45 -0800 (PST) Received: (from joe@localhost) by neptune.Stanford.EDU (8.8.5/8.8.3) id OAA14306; Mon, 23 Nov 1998 14:25:43 -0800 (PST) Message-ID: X-Mailer: XFMail 1.2 [p0] on Solaris X-Priority: 3 (Normal) Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 8bit MIME-Version: 1.0 In-Reply-To: <199811232215.OAA19264@magellan.Stanford.EDU> Date: Mon, 23 Nov 1998 14:25:43 -0800 (PST) Sender: joe@neptune.Stanford.EDU From: Joe Twicken To: rsimpson@nova.Stanford.EDU, hinson@nova.Stanford.EDU Subject: RE: ODR Notice: /users/z11/procODR/83272157 Content-Length: 877 Status: O The last three ODR's failed because /users/z12 is full.

In the occultation #192e recording, the one-way carrier is only present for about 100 seconds. During that time, there were no changes in the POCA ramp rate so it is also not possible to tell whether there was a sawtooth problem or not. I certainly will let you know if I do observe any sawtooth problems. I have been keeping current with processing the open-loop data, and have now processed all occultations through 219i.
