Organization & Staffing


Organization Staffing

• Staffing Varies With Mission Phase & Scheduled Activities

- Lunar Mapping Phase Requires The Most Support (10 Per Shift Plus Support StafO

-- 70 Days, 24 Hours/Day, 7 Days Per Week

- Staffing For Other Phases Is A Subset Of Lunar Mapping Phase Staffing

Science Manager, Sensor Engineer, & Data Manager Are Required Only When Experiments/Tests/Observations Are Scheduled

Operations Timeliner & Network Controller Are Single Shift Positions

-- NRL & GSFC Orbit Analysts Required For Once A Day Orbit Determination, Maneuver Planning, Maneuver Execution, & Scheduled Autonav Experiments

• LLNL & NASA SAC Representatives Are Present At DMOC

• Additional Support Staff To Each Function (Engineering, TAMP, Ground Systems, Science Planning, Data Processing) Are Scheduled For Offline Support

- Anomaly Resolution, Subsystem Engineering Support, Test/Experiment/ Observation Planning, Command Plan Generation & Verification, Mission Status Reports, Trajectory Data Generation & Distribution

(·X axis +1·70° to center of Earth) Based on current attitude &

orbit, Guidance will generate required attitude control parameters for the desired attitude and supply these parameters to ACS.

Guidance will generate desired attitude based on any attitude constrains, primary pointing requirements (nadir pointing), &

secondary pointing requirements (maximizing solar Incidence angle on solar arrays).

ACS will take the desired attitude parameters from guidance, compare with currant attitude, & generate required commands to go to desired attitude. The reaction wheels or thrusters will be used depending on amount of slew and time available for the slew.

The actual time to slew to the desired attitude will vary orbit to orbit.

Ground Segment Software - Configuration Procedures

• Track SIW Problem Reports

• Use A Code Management System To Track Code Changes At The Later Stages Of Software Development

• One Computer System Has Been Designated For Software Configuration Management (CM) & System Builds (MicroVax II- DSPDEV)

With C And FORTRAN Compilers I CMS I DECWindows-Motifinstalled

Dedicated For DSPSE SIW Development

• All Ground Software Will Be Delivered From The Designated CM Computer System To All DSPSE Support Computers

• CM Tools Will Perform Pre-Pass Configuration Validation On SIW & Data Files
