"The Secret Code of an HST Flight Controller"

Lynn Foster Bassford - March 5, 1996

    Editors note: I don't expect that many people will be able to fully follow the happenings below. But it may be interesting to see the special language that HST controllers communicate with

Day 065 Swing Shift Journal

Our main responsibility is to watch & analyze Real Time telemetry from HST. Here are a few examples of some of the activities that a Shift Supervisor might do in parallel. (Note that the SI Flight Controller is watching the science and the DMS Flight controller is watch his data at the same time (it's like putting together a puzzle) as the Shift Supervisor is doing the following:)


19:20 (2:20pm)  Staffing - Bassford On/Cooper Off  
        Verified  Ground System Computer Configuration
19:31 NSSC1 Load - Uplinked N28B9850L to Payload computer on HST     
        (NASA Standard Spacecraft Computer=3DNSSC1).
19:44 NSSC1 Load - Completed.  Science Instruments Flight Controller   
        verified Command counter and successful transmit for a good load.
19:00 Forward Service to HST ended for this Event
19:50 Talked with Data Management Subsystem Engineer about a report for
        our next weeks schedule (called NEWRUL) that may have a few invalid 
        data points. Need to use alternate report until NEWRUL has been fixed 
        (for about 40min).
20:01 LOS - return service for this event completed ( we get our   
        telemetry/data from a return service)
20:10 Gave briefing to STGT Controller for upcoming service
20:15 AOS - both the return and forward services for this event begin
20:18 Sent commands to HST & GCMR to STGT to begin tracking HST (Went Mode 1).
20:29 Sent commands to HST to complete tracking ('went Mode 2')
21:06 LOS for this event  
21:07 Gave briefing to STGT Controller for upcoming service
21:07 AOS for this event
21:10 Answered questions from several SE's about current commanding  
        configuration and our data base.
21:39 LOS
21:50 Gave briefing to STGT Controller for upcoming service
21:58 AOS
22:10 Received/logged/& photo-copied TDRS schedule changes from
        NCC for several times over next few days.
22:35 Sent commands to HST & GCMR to STGT to begin tracking HST (Went Mode 1).
22:47 Sent commands to HST to complete tracking (went Mode 2)
22:49 LOS for this event
23:05 Straightened out console documentation
23:10 Gave briefing to STGT Controller for upcoming service
23:13 AOS
23:29 LOS
23:35 Talked with Data Operations Control Center for initial requirements
        for setting up out Back up control center
23:47 Gave briefing to STGT Controller for upcoming service
23:52 AOS 
00:00 Day change to GMT day 066.
00:20 Worked on construction a new rotating shift schedule
00:27 LOS
00:29 Gave briefing to STGT Controller for upcoming service
00:34 AOS
00:50 Continued work on new schedule
01:12 LOS
01:17 Gave briefing to STGT Controller for upcoming service
01:20 Answered questions from FC's about tomorrow Servicing Mission 
        2 Simulation.
01:23 AOS (for both our Return & Forward Services)
01:30 Talked with Mike Kohout about configuring our VDS (phone systems) to 
        each Flight controller's needs for the Simulation.
01:40 Logged on to MVIP (terminal) to check out system for Simulation
02:10 Gave briefing to STGT Controller for upcoming service
02:16 LOS
02:17 AOS (both Return and Forward services begin)
02:20 Wrote up briefing for next shift's Shift Supervisor (my relief)
02:40 Verified validity of MVIP (terminal) brought into back up string
        for our back up command center.  Set up back up system to match 
        current Real Time string system.
02:49 Forward Service ends
02:55 LOS (return Service ends)
03:00 Tested back up system by sending a command through our line.
03:10 Started transferring Flight Controllers over to back up system at
        our back up commanding facility.  We'll use our back up facility for 
        the next day to run Real Time operations.  Our normal facility (MOR) 
        will be used to run tomorrow Servicing Mission 2 Simulation.  
03:25 Shift Briefing given for next 20 min to my relief.  At same time:
03:26 NSSC1 Load sent to HST's payload computer.
03:50 (10:50pm)  8 hour day completed.  Time for me to go home while 
                 another Shift Supervisor's day begins.
