メトリ送信装置。 Real-time telemetry signals mounted on artificial satellites, etc.
A telemetry transmitting device that multiplexes signals such as reproduced telemetry signals, ranging signals, etc. onto one carrier wave by phase modulation, etc., includes a modulator that modulates the carrier wave, a first subcarrier modulator that modulates real-time telemetry data, high frequency components of each modulated signal by connecting a first bandpass filter between the two subcarriers and a second subcarrier modulator that modulates the regenerated telemetry data. A telemetry transmitting device characterized by attenuating signal waves to prevent interference with each other's signal waves and transmitting without expanding the occupied bandwidth.
