The TX312 is a High Data Rate GOES Transmitter. The transmitter complies with the HDR specifications, and supports transmission rates of 100, 300, and 1200 bps. Diagnostics and status information can be sampled by the datalogger, and transmitted as part of the data stream. Automatic GPS correction of the clock and oscillator drift ensure continued data transmission.
