S-Band TDRSS / Deep Space Network (DSN) Transponder
This product has been discontinued
This S-Band Transponder (SBT), developed by General Dynamics, can communicate with both NASA’s Space Network (SN) and Deep Space Network (DSN). Four user selectable frequencies are available including the SN multiple access frequency. Additionally the SBT can function as an inverse SN transponder allowing communication and ranging between two spacecraft or another element on the end of the same link. The SBT’s extensive functionality should satisfy the needs of almost every near-earth mission.
