This occultation was successfully captured at DSS 14, however. Aseel Anabtawi reports that three DRs were written over this DSS 26 pass: G102500, G102499, and G102498. Analysis -------- Joe Twicken has analyzed additional test data acquired recently to check USO stability on longer time scales than is possible with typical occultation recordings. His (slightly edited) report: One-way open-loop data were acquired at DSS 14 (with telemetry on) during two MGS orbits on 2003/065 for the purpose of characterizing "long-term" USO frequency stability. These recordings did not include occultations, permitting the calculation of meaningful Allan deviations at integration times up to approximately two minutes. Results from the processing of these recordings are shown in the tables below. The Allan deviation measurements at the longer integration times (32 seconds and greater) are generally worse than were observed in the 2003/036 one-way stability data at DSS 63. This is due in part to a slope in the frequency residuals of 35 mHz over each 24 minute recording. The residual slope in each recording may be attributable to a shortcoming in the orbit reconstructions. There was no attempt to compensate for HGA motion in the processing of these recordings.
