Aiming at the multi-address access requirements of relay TT & C and multi-station TT & C communication in outfield test and solving the problem of illegal data reception in the test, a frequency hopping TT & C communication system based on AD9361 + Zynq SOC hardware architecture is designed, which uses PCM/FM modulation in both uplink and downlink. The system supports both continuous communication waveforms and time-division frequency-hopping communication waveforms. The infield test results show that the frequency hopping measurement and control system works stably, receives data reliably, and has the characteristics of simple task planning and flexible node configuration.
