This was in response to concerns over signal stability at this antenna and expectations that DSS 24 would be scheduled for increasingly more data acquisition. His (slightly edited) report: Four ingress occultations (19114i-19117i) were recorded on 2003/169 at DSS 24. I have processed each open-loop recording, and determined nominal SNR and Allan Deviation over a range of integration times. This was the day that normal operations resumed after a 7-day MGS C-mode period. I have also determined nominal SNR and Allan Deviation for four open-loop recordings on 2003/161 at DSS 25 (19017i-19020i, just prior to C-mode), and for three open-loop recordings on 2003/170 at DSS 15 (19127i-19129i). It should be noted that minor data quality issues with the 2003/170 data at DSS 15 were noted in the daily MGS RST Health Report (1 dB steps in the baseline with two of the recordings and +/- 0.5 dB fluctuations with the other). The results may be found in the tables below. As was evident the first time that open-loop data were recorded at DSS 24 (2002/344), the frequency stability at that station is very good in comparison with the other SPC 10 stations at the longest measured integration times (8 seconds and greater). At 4 seconds, the performance at DSS 24 was generally comparable or better than that at the other SPC 10 stations analyzed here. At the shortest integration times (2 seconds and less), the stability at the other SPC 10 stations was generally better than that at DSS 24.
