  • 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

  • Use TCP protocol. The use of TCP protocol provides ability to teleoperation.
  • All transmitting data includes 6 bytes additional header.

Time

  • 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

conclusion
Conclusion
  • 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
development plan
Development Plan
  • Make a function for storing all telemetry
  • Integration test with Radio
  • Test, test, test, test……………………………..
  • Make operation plan for Ground Support Software
