1. A telecommand and telemetry simulator of micro-satellite air floating platform is introduced, which hardware is industry control computer and wireless network card.

2. An experiment of simple telecommand application system is introduced in this paper. The basic thought of design, the compose of the system and the operation principle is described in detail.

3. A telecommand and telemetry simulation software of ground station for BUAA micro - satellite is introduced.

4. With the method mentioned the entropy of telecommand messages will obviously be increased and the security of transmission enhanced as well.

5. Telecommand operation platform is empoldered for implementing telecommand operation mode by the space control center.

6. Considering the requirement of space telecommand(TC) development in China, the author thinks that there are some sorts of topics that must be researched at present.

7. OBDH simulator is one of the most important components of the flight control simulator, which simulates telemetry, telecommand, and communication functions of a spacecraft.

7. Sentencedict.com try its best to collect and make good sentences.

8. To make sure that the antenna points to the right direction is the basis of effective work of telemetry and telecommand system of a helicopter.

9. The channel error control measures applied with the message extension method were also studied. The entropy of telecommand messages would be obviously in...

10. In this thesis, a brief review and analysis of the development of spacecraft telecommand system has been given and Packet Utilization Standard(PUS) suggested by ESA has been studied.

11. The rules to be obeyed in program realization are summed up in insuring the reliability of telecommand and teleadjusting.

12. The test result shows that the communication effect between the micro-satellite air floating platform and the telecommand and telemetry simulator is satisfied.
