TRIO-CINEMA 2 KHU, 10/08/2010 Agenda List IGSS(Integrated Ground Support Software) Overview Integration Test Development Plan

TRIO-CINEMA 3 KHU, 10/08/2010 IGSS overall overview Integrated Ground Support Software (IGSS) Attitude Simulator (Matlab/simulink) CINEMA Emulator GSEOS Mission Planning System Satellite Tracker (Orbitron) Orbit Simulator (STK or Orbitron or hand-made) Radio System CINEMA Radio Not determinedIn progress

TRIO-CINEMA 4 KHU, 10/08/2010 IGSS overall overview(continued) Integrated Ground Support Software (IGSS) Attitude Simulator (Matlab/simulink) CINEMA Emulator GSEOS Mission Planning System Satellite Tracker (Orbitron) Orbit Simulator (STK or Orbitron or hand-made) Radio System CINEMA Radio Not determinedIn progress Use RS232 communication. One is Transmission line for tele command. Other is reception line for telemetry. All data is packetized by CCSDS and CTM definition

TRIO-CINEMA 5 KHU, 10/08/2010 IGSS overall overview(continued) Integrated Ground Support Software (IGSS) Attitude Simulator (Matlab/simulink) CINEMA Emulator GSEOS Mission Planning System Satellite Tracker (Orbitron) Orbit Simulator (STK or Orbitron or hand-made) Radio System CINEMA Radio Not determinedIn progress Use TCP protocol. The use of TCP protocol provides ability to teleoperation. All transmitting data includes 6 bytes additional header.

TRIO-CINEMA 8 KHU, 10/08/2010 Test Outline Integrated Ground Support Software (IGSS) GSEOS Mission Planning System Flight Software TCPRS232 Operator Console Operator commands MPS to start communication MPS transmits a packet to GSEOS for changing flight mode GSEOS decodes commands transmitted from MPS and generates actual command GSEOS transmits actual command including packet header FSW processes command Processing result can be applied to Housekeeping telemetry. In this case, Flight mode and some variables will be changed GSEOS receives telemetry and decodes it Changed Housekeeping data can be shown by GSEOS to Operator Assumption - Telemetry should be transmitted from FSW to GSEOS every 10 seconds - We have no Mission Planning System, so we made simple MPS containing few basic functions Eyes Time

TRIO-CINEMA 10 KHU, 10/08/2010 Test Result BeforeAfter GSEOS Mission Planning System Flight Software

TRIO-CINEMA 11 KHU, 10/08/2010 Make basic mechanisms and interfaces for operating GSEOS Use actual command defined in CTM instead dummy command In order to operate automatically, also we designed communication protocol and transaction between Mission Planning System and GSEOS Conclusion

TRIO-CINEMA 12 KHU, 10/08/2010 Development Plan Make a function for storing all telemetry Integration test with Radio Test, test, test, test…………………………….. Make operation plan for Ground Support Software
