Anomalies:
* G-20: DR # G02694 - Delayed AOS from 14:25:00 to 14:36:07 due to
incorrect
Rcvr predicts. Used
'sky' predicts from Book.
* G-21: Received TPOCC event message " Tlm decom could not read
telemetry packet from packet extractor - closing connection. Return link 1
and 3 to Packet Extractor frame client was terminated without proper clean
up.
MOR string crashed as a result. MOC software recycled and Operations
continued in the MOR.
Actvities:
1. Played back SSR B - 578 slices. Redumped 236 slices. Had to
redump slices 0-181 due to the MOR crash. FOT had not yet logged which
slices needed redumping.
2. Sent SIS commands at PI's request (CR#16).

DR# G02797 for problem with channel 1, switched to channel 2. Caused
delayed in acquisition of high data rate at beginning of pass.

13:30:33 - AOS at D24 at low data rate format - RTSW
14:00:00 - Expected AOS at D24
14:03:00 - Range mod ON
14:03:58 - Downlink command didn't reach s/c, resent after a /RESYNC, high
data rate acquired at DSN but then problem occurred with channels.
14:20:00 - Acquired high data rate after DSN switched to channel 2
14:25:00 - FDF requested doppler rate change - DSN reported SOE incorrect
for doppler rate requested
14:38:00 - Started redump of SSR A begun on day 286 (slices 246 - 960)

Pass Highlights: Station AOS LOS
D16 14:07:00 18:15:00
Pass Summary: Good pass with NO problems from DSN. Both recorders were in
idle with "Bin Fired" flag - Bin #42 SSR safing bin checked, next time get
time of bin fire. Started SSR A recording, SSR B playback. SWIMS, SWICS,
SEPICA, SIS, CRIS ops done.
Anomalies:
MOCR's written for 1. G_INITIAL_CONTACT - need /RESYNC at beginning and
a cmd was dropped.
2. SEP_30KOP - line 149 has an
apostrophe in the same line as /SEND and TPOCC flags an error
3. C_RTSW - line 182 checks for a
mnemonic not found in RTSW format
Activities:
Pre pass activities were not completed-oracle password unknown so backup
DPS not completed
14:07:00 - AOS D16
14:15:00 - Expected AOS at D16
14:19:00 - VC2 arrived at MOC
14:25:00 - Changed to Autonomy 1 format to check for Bin Fired. Bin #42 -
SSR safing bin fired
14:28:00 - Sent Telltale Clear - next time find out time that the bin fired
- miscalculated SSR record time
14:40:00 - Put SSR A in record
14:43:00 - Put SSR B in playback
14:47:00 - FDF requested ADC format
14:50:00 - Returned to Science format
14:51:00 - SWIMS operations - HV session 2
15:01:00 - SWICS operations - HV session 2
15:38:00 - SEPICA operations OCR#50, #49

17:02:00 - SIS and CRIS operations using OCR#43
17:25:00 - SIS and CRIS operations completed
17:50:00 - Abort bit sent to SSR B - stopped at slice 725

Pass Highlights: Station AOS LOS
D24 13:56:00 18:20:00
Pass Summary: Good pass with no data drops. DSN was sending monitor blocks
from two stations corrected by Ops chief who said to call Track Control if
this occurs again. SSRA dump complete with SSRB recording. Miscompares due
to GRI not updating- IDR'd.
Anomalies:
1. Sent command to SSRA to read segment 0 slices between 960 - 1023 to
complete dump for day 271. Command rejected by SSRA with LAST_COM_INV_A
flag set to 1. We resent command - rejected- then sent Abort Bit to reset
the flag to 0. Before this playback
ended at slice 579. Possibility that slice playback numbers were greater
than what could be played back at that time?
Activities:
13:56:00 - AOS at D24
14:05:00 - Expected AOS at D24
14:08:00 - Range Mod ON
14:10:00 - Downlink command went out for high rate data
14:12:00 - High rate data arrived at MOC - 2 minute acquisition
14:20:00 - Tried to playback SSRB for redump - REC_PLAY_SEL = SSRA
therefore SSRB was playing back but CDHA did not see this. For non-nominal
ops of SSR's - check this parameter. It is set in G_INITAL_CONTACT to SSRA.
14:58:00 - SSRB placed in record mode
15:01:00 - SSRA placed in playback mode
15:09:00 - SWIMS operations begun
15:20:00 - SWICS OCR #51 operations begun
15:39:00 - DSN sending monitor blocks from 2 stations - reset - call Track
Control next occurrence
17:32:00 - SSRA redump - command rejected by SSRA
17:45:00 - SSRA redump terminated
18:09:40 - Downlink command sent for RTSW
18:13:54 - RTSW data arrived in MOC - 4 mins 14 secs acquisition time
