Provide amateur radio communications via the 145/435 MHz transponder and SSTV. Download pictures from the 640×480 pixel camera. Operate the data downlink at 38400 bps QPS. Compare the performance of the data downlink when using AFSK, GMSK and QPSK modes. Demonstration of π/4 shift QPSK transmitter. NEXUS performs data downlink by π/4 shift QPSK transmitter using the amateur radio band. We will perform the new radiowave format fast communication between satellite and groundstation To evaluate its superiority, against the communication speed. |
