Activities:

Data Capture: 99.995%  2016 DOY 094 - 2016 DOY 101

Notes:

* As a consequence of the DOY 094 DSS-65 lost pass (as described in last
week's report; S-ACE-35-CTT-2/DR #M109280), an autonomous SSR fail-over
was performed on DOY 095. The SSR failover transition was responsible for
32 seconds of data loss (gap time frame: 2016-095:17:18:40z -
2016-095:17:19:11z).

* Data gap totaling 4 seconds occurred during SSR management/playback
activities on DOY 099 (gap time frames: 2016-098:02:59:44z -
2016-098:02:59:45z and 2016-099:22:33:37z - 2016¡©-099:22:33:38z).
