• Use TCP protocol. The use of TCP protocol provides ability to teleoperation.

• All transmitting data includes 6 bytes additional header. Special characters(2bytes: 0xEE 0x16)

Opcode(1byte)

Reserved(1byte)

Data field length(2bytes)

Data(0~65535 bytes)

Test Outline

Integrated Ground Support Software (IGSS)

GSEOS Mission PlanningSystem

FlightSoftware

TCPRS232 OperatorConsole

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

• 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
