Alternate ACE Checkout
Alternate STR Checkout
Primary Processor Checkout
Alternate Bus Adapter Checkout
Below is the correct statement of the recommended HOP ACS 1 schedule, except
should be executed every 2 years
Can be Called from COP
Should be Performed after equinox season
Should be Performed during equinox season
Below is the list of procedures that call HOP ACS 1, except
. COP ACS13, Anomalous Gyro Behavior
. COP ACS3, ACS FDIR Monitor Trip
HOP ACS 6, Alternate STR Checkout
. HOP ACS5, Sun Sensor Health Monitoring
During nominal MPSAT condition, based on the chart, what step should we choose after entering step 2.1?
Go to Step 2.5
Go to Step 2.2
Go to Step 2.7
Go to Step 1
Why do we have to change the swap ACE configuration on the primary processor to be the same as the active ACE during execution of this procedure? All the statements below here is correct except
To avoid the possibility of two processors being configured as Bus Controllers to the same ACE in the event of an FDIR trip
To allow a predictable path to elevate FDIR to a processor swap
To prevent two processors attempting to communicate to the same ACE as Bus Controllers
To Collect data from primary ACE
Below are the list of ACE trays that are monitored by the ACE MBUS Global and Individual Monitors, except
Sensors
Thrusters
Reaction Wheels
MPS and LSE Trays
During the step where the operator should Plot RW Data for each RW for 5 mins from both processors, these telemetries should be monitored by Operator except
RW ON/OFF Status
RW Motor Current
RW Motor Power
RW Averaged Tach
During the check of the He and MST LV polarity statuses from both processors, the operator should expect the CLOSE status from these equipments except
MST Ox Latch Valve
Fuel HE Latch Valve
MST Fuel Latch Valve
22N Thruster Latch Valve
During the execution of HOP ACS 1 on November 25th, on step 9.7, what action did SCA decide to take before going to Mbus configuration step?
Review remote absolute address using memory management tools
Assumed there are non-zero values in the addresses then continue to step 999
Assumed there are no non-zero values in the addresses then continue to 9A
Assumed there are non-zero values in the addresses then continue to 9.9 and 9.10 to cycle the bus adapter mode
All of these statements are true about MPSAT Attitude Control Electronics (ACE), except
Each stack contains a Bus Interface Tray (BIU) and three trays necessary to interface with the attitude control sensors and actuators
ACE is a unit connecting the sensors and actuator in ACS subsystem
ACE is configured as a primary stack and a redundant stack
Normally, only the primary ACE is powered and the redundant, or standby, ACE is unpowered (off).
