I need a spacecraft state vector to initialize my Doppler predictions; if the velocity is wrong, the Dopplers will be wrong (and the FROs will be bad). Ordinarily I compare things like incidence angle, specular point latitude, and specular point longitude in my Doppler calculation against the ones that come out of the first-round geometry calculation; they should agree to small fractions of a degree. Perhaps because I hadn't done one of these for a couple months, the errors slipped through (I was a couple degrees off in all three of my test quantities). I discovered the error when I recalculated the geometry and Doppler before processing the 100 kHz data from day 106. Fortunately, the 100 kHz data look fine; it's just taking 4 times as long to get the answers (and a lot larger files). So, I think the method for setting the FROs is still OK; I'll just have to be more careful in my error checking. The experiment on day 128 will be a good test of how accurantely I can calculate the FROs ... the need for an X-Band frequency change every minute means small errors can have big effects. But everything looks good so far in the predict area. PS: I have downloaded all of the BSR data from 121 to Stanford, backed the files to DVD, and erased the originals on rsops2. There is still a pair of gravity files on rsops2; I'll pick those up in the next couple days.

As you can see from the attached pictures, the o= uter shield of the connector that connects the S-HEMT to the Post Amplifier= is broken. The whole cable and connectors have been replaced, and the po= st checks using the ACME systems are nominal. Dick Simpson Reports: 21 July 2010 As reported at the last telecon: S-RCP stability is no longer a problem. S-LCP had another 2.5 dB event. Not known at the last telecon: S-RCP Tsys is about 4K higher than expected, but this is a tangent we should probably not mix with the issues already on= the table. DOY 194 BSR Report: These appear to be good data. Anomalies: Gravity data scheduled for collection on 2010/189 at DSS 15 wer= e lost when the antenna could not be pointed (DR G110330). DOY 184 BSR Report: Anomalies: There was a 2.5 dB drop in output from the S-LCP RSR at 18:39, just as the surface observations were beginning. The anomaly lasted about 5 minutes. Similar anomalies have been seen in S-LCP data collected at DSS 63 on days 106, 135, 142, and 170, usually at elevation angles near 45 degrees. Susan Kurtik has organized a task force to investigate the problem; it has been discussed during conference calls on days 180 and 187. There were also two short drops during the post-cal (with the antenna at stow); the first at about 20:13 was about 1.5 dB and the second at about 20:54 was about 0.7 dB. Each lasted only a few seconds. S-RCP, which has been generally unstable at the 0.2 dB level over the past three months, performed much better during this experiment. The task force (above) was advised that, because of a power failure, the S-RCP maser had gone through a full cool-down procedure; contaminants may have been cleared out, leading to better performance. There was no evidence that the X-RCP noise diode was turned on at any time during the ground pre-calibration. The reason for this is unknown. At the beginning of tracking, the noise diode operated normally during the 'mini-calibration'. The noise diode also operated normally during the post-surface mini-cal and the post-calibration. The one-way ingress occultation was captured at X-Band (and possibly S-Band). The one-way egress occultation was captured at X-Band. Very weak S-RCP surface echoes can be seen just before ingress; very weak S-LCP echoes can be seen at the beginning of the surface observations. With Earth-Mars distance approaching 2 A.U., S-Band echoes will be increasingly difficult to capture.
