Real-Time Telemetry Transmitters 

 Telemetry Transmitter Switch

Selects the transmission of vital spacecraft system parameters to the ground stations in real-time or delayed-time. It provides a radio frequency (rf) link from the spacecraft to ground communication facilities for transmission of various data obtained by the Instrumentation System. Real-time transmitter is powered by placing the TM CONTROL switch to the R/T & ACQ position. Delayed-time transmission may also be initiated by placing the T/M CONTROL switch to the R/T-D/T position. If the CMD position is selected, only the acquisition aid beacon will operate.
