S-Band Transponder is a communications system manufactured by L3Harris / General Dynamics. It features typically dual-redundant redundancy.
ABOUT S-BAND TRANSPONDER
The S-Band transponder provides two-way communication between launch vehicles and ground stations operating in the 2.0-2.3 GHz frequency range. It handles telemetry downlink, command uplink, and range safety communications. S-band has been the workhorse frequency for launch vehicle communications since the 1960s.
OPERATING PRINCIPLE
Superheterodyne receiver/transmitter operating at S-band (2.0-2.3 GHz) for telemetry, tracking, and command
VEHICLES USING THIS SYSTEM
