## Instrument Support Facility Operations Concept

-  Nominal 40 Hour Work Week
-  IOT Members On-Call for Anomalies/Emergencies that may occur during off-shift hours	-> Automatic Paging from ISF Computer
-  Autonomous Monitoring, Trend Analysis
-  OASIS for Interface to MOC for Data Collection, Monitoring, and Command Requests
-  Provide Command Block Updates to MOC as Necessary.

## Instrument Support Facility Operations Commanding

-  Routine Activities
-  Special, Known Activities, i.e., Laser and other redundant subsystem switching; DEM updates; targets of opportunity.
-  Anomalous Events
-  GPS

- IGS MOWG 2

## Instrument Support Facility Operations Commanding Concept

-  Request Command Block to be Radiated
-  Specify Execution Time / Constraints if any
-  Supply Memory Uploads if Required
-  Confirmation of Receipt and Radiation

- IGS MOWG 2

## Instrument Support Facility Operations Monitoring

-  Temperature, Voltage, Current Displays	-> Alarm Indicators, Red and Yellow Limits
-  Alarm Pages
-  Status Pages

- Realtime Data :

-  Background Task
-  Output Results to Logs / Reports

- Playback Data :
