L-3 Cincinnati Electronics (CE) continues to broaden is offering of TDRSS compatible receivers and transmitters. Virtually any TDRSS forward or return service can be utilized with the following products. All TDRSS products have been live link tested with the TDRSS constellation to insure compatibility.

  • CR-312 S-Band Dual Mode TDRSS/BPSK Digital Command Receiver
  • T-715 S-Band TDRSS MA/SA Telemetry Transmitter
  • T-719 S-Band Configurable TDRSS/QPSK Transmitter
  • T-720 Ku-Band TDRSS Compatible Transmitter

CR-312 S-Band Dual Mode TDRSS/BPSK Digital Command Receiver

00Model CR-312 is an S-Band TDRSS/BPSK digital command receiver features advanced digital signal processing techniques implemented in radiation hardened Field Programmable Gate Arrays (FPGA). This digitally based design approach delivers superior, repeatable receiver performance and reliable operation over the entire range of signal dynamics and environmental conditions experience in the space flight environment. Despreading, carrier acquisition, doppler tracking, carrier demodulation and bit synchronization are all performed digitally to produce the baseband data and clock output. Additionally, the receiver features auto modulation and data rate detection capabilities.

  

 

T-715 S-Band TDRSS MA/SA Telemetry Transmitter

00Model T-715 is an S-band TDRSS Multiple Access compatible telemetry transmitter. The unit is compatible with TDRSS Data Group 1 Mode 2 and Data Group 2 modes. Offering commandable forward error correction and pseudo random (PN) spreading, the T-715 provides flexibility for various mission scenarios. Weighing less the 5 lbs with and RF output power greater than 38 dBm, the T-715 can also be factory tuned in frequency to operate with one of the many TDRSS single access S-band telemetry channels.

T-719 S-Band Configurable TDRSS/QPSK Telemetry Transmitter

00Model T-719 is an S-band dual mode TDRSS/GN transmitter compatible with TDRSS SA SQPN return service. The transmitter is unique in the fact that it can be commanded into a GN BPSK/QPSK mode or a simultaneous TDRSS SQPN and GN BPSK mode. The unit has commandable rate 1/2 forward error correction along with either single channel or dual channel SQPN operation. The SSPA delivers 5 Watts EOL at the output of a transmit filter the limits emissions.

  


T-720 Ku-Band TDRSS Compatible Transmitter

00Model T-720 is the first generation Ku-Band TDRSS compatible transmitter building upon an extensive X-Band product heritage by adding an up-converter to a heritage X-Band modulator. This unit is optimized for the TDRSS Ku-Band Single Access (KuSA) Return Service centered at 15.0034 GHz. Customizable to virtually any data rate supported by KuSA Return Service, the T-720 offers extraordinary flexibility. The unit can be configured with a 10 Watt (EOL) SSPA or with a 10 dBm output to drive a TWTA. Commandable rate 1/2 FEC and NRZ-L to NRZ-M data conversion are also supported.
