Based on principle of multi-functional miniaturization and low cost we designed a kind of UAV TT&C system adaptive for autonomous operation and multi-aircraft cooperative combat.The system is based on Time Division Duplex (TDD)and Time Division Multiple Access(TDMA) and selects the data radio as the hardware platform.Moreover the system uses the CF card as the storage medium and integrates telemetry data recording and playback functions.It can realize semi-real-time and non-real-time measurement and control function when communication link breaks.
