Clementine Workshop Notes -------------------------- Operations: Task grouping: started with all the tasks and grouped them (meta chart concept) Categorized them into 9-5, 24 hrs, time scales Minimize people needed (& around the clock) Define schedule clearly -> avoids overstressing ops personnel Rehearsals to test s/w, h/w and ops sequences Staff = 32(full), 30(support), 15(part time), 24(as needed) These included programmers, managers, admin, tests, But does not include the science team Did not really have a hit by the truck scenario Jobs: (8 people) Trajectory analysis, science planning - overtasked, scheduler - mainly external, ops controller, spacecraft engineer - monitered the craft state+ cmd, software engineer - testbed ops & overtasked, data manager - verify data integrity & quality?, sensor specialist. Commands were always tested on the testbed before sending out and verfied by the commanders. There were instances of the testbed not catching the problem (~1/week) * Ability to change h/w on the fly - add, update (2 yrs) S/W assistance everywhere - User Interfaces critical here Science Mission: Trevor Philosophy: minimize distance between science team & spacecraft mission team: eliminated paperwork & layers ->Single point contact Prioritization of tasks helped a lot In flight calibration Relied on software engg. to test pointing quaternions - some problems got through - no simulator ? Contacts (names, phone,e-mail,fax, speciality, contribution) ------------------------------------------------------------ Trip Summary ------------- Be is a stiff structural material, in addition to having high heat capacity Gyro is the way to go (6 kg, 10 W, mRad accy), not a tech difficulty & enough time to work the environmental problem. Dick Miligue is the way to go... Dedicated Ground station is a must (we can configure as needed and run tests) Laser comm system possible (Mimic program at Arpa) Solar Array Brittleness was not a problem (what kind, what eff, mounts?) Careful with acoustic noise effect of a Proton on Honeycombs, what matters mass/unit area and distance bet reinforcements Be very careful with the Russian space machinery - telemetry specs of a proton need higher margins, any facilities we would need have to be verfied to be operational and funded for 2-3 years Very possible to do an recalibrable striping sensor system for < 400k, need reworking to the problem)
