Subject: IBEX Successfully Recovered : BCR Reset
 
Hello Team,
 
IBEX has been fully recovered from the BCR Reset via CAR 523, which was
approved at the 4pm FRB. This reset and recovery had no effect on the
data collection and no data was lost. Spacecraft bus and payload systems
are all nominal and properly configured.
 
During the 2100 UTC contact, the spacecraft was returned to reference
power tracking, the heater setpoints were changed to 16/18, the PCM
switch telemetry was changed to reflect the observed power states, and
the gyro was changed to non-inhibited. The CAR was executed according to
plan.
 
Thank you very much to Tim, Sheral and Bret for their quick diagnosis,
recovery planning and flawless recovery execution. Thank you also to the
team members who provided input to and/or attended the FRB on short
notice. It is wonderful to work with such a knowledgeable and efficient
team! Great job!
 
Go IBEX!
Chelle

Subject: RE: IBEX FRB: 4pm EDT TODAY : BCR Reset
Attached is the Recovery CAR to be discussed at the FRB. Recovery
contact 2100- 2200 UTC.
 
SC State: Science
PL Mode: HVSCI
Star Tracker: On, collecting valid quaternions
Data Collection: Uninterrupted, SSR pointers intact, CEU reported spin
period 14.328 (receiving valid pulses from ACS, did not return to
default period of 14.385)
Uptimes as of ~1820 UTC: 
ACT : 7336095
FC : 7894935
BCR : 324255
 
PCM-B defaults :
Reference power tracking (change to peak power tracking)
CEU 5V OFF (needs to be changed to reflect proper power state of ON)
PCM-B 28V2 OFF (needs to be changed to reflect proper power state of ON)
 
BCR Processor Reset Procedure : S924-OP31434 (used for reference)
BCR Reset Recovery Procedure : S924-OP31004 
 
No recent high solar activity

Subject: IBEX FRB: 4pm EDT TODAY : BCR Reset
Hello Team,
 
During today's apogee contact it was found that the BCR had reset since
the last contact. The SC State is Science, the payload mode is HVSCI,
data is still being collected. A BCR Reset is transparent to on-board
science collection operations, but a few default values need to be
changed to our current operating values (peak power tracking, heater
setpoints, PCM-B switch readings, etc.).
 
We will discuss the reset and recovery actions at an FRB at 4pm EDT
today. Bret will present a CAR with response actions.

Thanks,
