6 WHAT IS AGO? Replaces ALL Operators In operation for 24 months at ADF-C & BP Over 140,000 contacts supported automatically Automated Schedule Generation & Deconfliction Automated Ground Resource Allocation & Monitoring Automated Spacecraft Monitoring & Contact Plan Execution Automated Personnel Notification 6

7 AGO HISTORY In 2006, BP was directed to develop a fully automated system High risk program Maximize cost savings Prove it can be done AFSCN incorporated automated pre-pass procedures to support this effort Since then it has been adapted to more than 15 satellites at BP 7

8 SCHEDULING & DECONFLICTION 8

9 RESOURCE ALLOCATION Hardware Architecture supports dynamic component allocation (no fixed hardware strings) Inference Engine deconflicts and matches highest priority, functioning equipment to a contact Future allocations predicted (look ahead) Ground telemetry stream created from hardware status Decommutated Alarm & Limit checking Derived processing 9

10 DYNAMIC HARDWARE CONTROL Matrices allow automated changes Real-time status collected from all hardware Real-time reconfiguration Failed components removed from future consideration Allows for partial solutions 10

11 SPACECRAFT MONITORING & CONTACT PLAN EXECUTION 11

12 CONTACT PLAN EXECUTION Plan Execution Execute Tasks Monitor command windows Single contact control

13 CONTACT MONITORING Monitors system for proper: Configuration Pre-pass Resource allocation Setup Configure hardware & software Telemetry - % collected vs. % expected Commanding - % successful vs. % attempted Plan execution - tasks completed vs. total tasks at (t 1 et + t 2 et t n et) > (x)% Shutdown Deconfigure hardware & software Post-pass Data processing & dissemination 13

14 SPACECRAFT MONITORING Derived status equations: Logical Mathematical Mission rules & constraints Database defined logic determines satellite & subsystem health 14

15 CONTINUOUS MONITORS Software 3 types of software monitored Constant Always running Transient Comes up & down with each contact Cron Table Hardware Interrogated at least every 20 seconds Ack/Nack response & configuration validation Daemons monitor CPU s, disks, memory, etc. Derived Hierarchy Trees Proper execution = Event Non-Critical component failures = Warning Critical component failures = ERROR 15

16 AGO EXECUTION & MODES System sets up as if operators were present Operator workstations are configured Control Automation disabled by single click Level of automation selectable by individual spacecraft & ground system Individual contact instance Modes Monitor Potential actions reported, not executed Assist Operator prompted before for concurrence Auto action executed automatically 16

18 FAILSAFE MONITORING 18

19 OBSERVATIONS Reduced Costs No recurring costs for 4 shifts of operators Decrease in overall system errors Resolves human related problems Every task executed on time, every time No improvising No Human Error Lacks human related ingenuity Can t adapt dynamically Every task executed on time, every time 19

22 LIGHTS OUT EXECUTIVE LO is designed to: Do what the operator would do NOT do anything unauthorized AGO executes files written by Spacecraft & Ground System Engineers Detects errors and Initiates files to take corrective action Files send whatever commands are necessary including safing the vehicle Notify engineers of the status Each mode is selectable by individual spacecraft and ground system Scoring for Hardware, Software, Contact, Spacecraft Selectable Automatic notification via text message, , and/or pop-up 22

23 NEXT STEPS AFSCN automation required for non-nxx systems 22 SOPS on board Test plan development is progress Testing will start this 1 st Quarter FY10 Real-time status to AFSCN More sophisticated scheduling algorithms Dynamic scheduling modifications Priority adjustments 23
