OCRs:
Update: ACE-378 Authorization to command to ACE Spacecraft from virtual MM=
OC (vMMOC)
FOT continue to work with WS1/WFF Personnel to resolve on-going WS1 issues:
Fanout connectivity, WS1 schedule delivery and System Status log access
- WS1 test pass supported on 04/05/2017. All playback data recovered witho=
ut incident;
manual intervention not required.
- NEN Engineer provided FOT with public key credentials. MMOC SAs will upd=
ate nenso
user configuration. Once completed, FOT will coordinate test delivery of N=
EN schedule.

Anomalies:
4/08/2017 DOY 098 S-ACE-93-CTT-12 DSN Problem D15 - Goldstone Complex
There was a telemetry dropout during the carryover playback at the start of=
the support.
Station reported "Carrier dropped out of lock unexpectedly. Loss of 2 way D=
oppler,
telemetry and Ranging. Halt All and SYM RESET was performed on DC11 followe=
d by an ACQ
CAR and ACQ SYM. Carrier in lock at 17:34:14z, Telemetry in lock at 17:34:4=
3 and Ranging
in lock at 17:36:02z"(DR# G118035).
IMPACT: Unrecoverable data loss totaling 213 seconds (~3.55 minutes).
4/13/2017 DOY 103 S-ACE-35-CTT-4 DSN Problem D65 - Madrid Complex
Ops Chief notified FOT @ 08:18z that D65 had a system trip and had to re-es=
tablish the uplink.
The station=92s SLE command system was waiting for the MMOC. DSN reported =
that =93S250W Transmitter
down due to 'Open interlock: Microwave interlock or Key Switch is Safe' ala=
rm." Corrective action
included "1W D/L signal acquired. Interlock cleared by ILR. Permission gran=
ted by OPS Chief to
perform a new uplink acquisition at(08:02:35). CMD E at 08:03:30. 2W D/L si=
gnal reacquired at
08:03:34, TLM locked at 08:04:01 and RNG lock achieved 0:05:36. (DR# M10992=
1)=94. FOT notified
the Ops Chief that the MMOC software would automatically reset the command =
link prior to
issuing its next command.
IMPACT: Minimal. Uplink capability lost for about ~6 minutes. Affected S=
SR data redumped;
all data successfully recovered.
