To meet the needs for low-cost, compact and light-weighted telemetry transmitters for small sounding rockets, we developed the S-band Miniature Telemetry transmitter (SMT). The first model of SMT has been developed for Viper rocket and the specifications are; Tx frequency: 2,280.5 MHz, Tx power: 200 mW, Modulation: PCM-PM, Bit rate: 102.4 kbps, Input: 14 ch (analog), Weight: 200 g, Size: 32 mm diameter x 100 mm. The second model of SMT is also developed to meet the needs for other sounding rockets. We achieved higher bit rate and higher Tx power. We also achieved direct BPSK modulation and additional digital signal inputs. The first and second types of SMTS were onboard four sounding rockets and they functioned successfully. The second type will also be onboard the M-V-8 rocket and will be used for the image data transmission of Sub-payload subsystem.
