Telemetry Tracking and Command (TT&C)

L3 Cincinnati Electronics (L3 CE) offers a variety of TT&C Receivers and Transmitters for various mission requirements. L3 CE can customize any of the products listed below to fit any mission command and telemetry needs.

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

Model CR-312 is a S-Band TDRSS/BPSK digital command receiver featuring advanced digital signal processing techniques implemented in radiation hardened Field-Programmable Gate Arrays (FPGA). A digitally-based design approach delivers superior, repeatable receiver performance and reliable operation over the entire range of signal dynamics and environmental conditions experienced 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. Contact Business Development and request a data sheet

CR-313 S-Band Configurable Digital Command Receiver

Model CR-313 is a S-Band configurable digital command receiver. This receiver features advanced digital signal processing techniques implemented in radiation hardened Field-Programmable Gate Arrays (FPGA). Due to the digitally based design approach, the receiver can be configured at the time of manufacture for a variety of command uplink waveforms, including NASA Spaceflight Tracking and Data Network (STDN), BPSK, and Residual Carrier Direct Modulation, as well as USAF SGLS (Space-Ground Link System).

CTT-520 S-Band Multimode Transponder

Model CTT-520 is an S-Band Multimode Transponder providing full-duplex communications with a variety of NASA networks and protocols. Compatible systems include the Tracking and Data Relay Satellite System (TDRSS) Space Network (SN), the NASA Ground Network (GN), the NASA Deep Space Network (DSN), and the Universal Space Network (USN). Also supported, the Common Communications for Visiting Vehicles (C2V2) protocol used on the International Space Station. The C/TT-520 is a flexible hardware and firmware solution adaptable to a variety of missions and applications. Contact Business Development and request a data sheet

T-710(B) S-Band BPSK/QPSK Telemetry Transmitter

Model T-710(B) is a low-power lightweight (4.5 lb.) factory selectable (BPSK/QPSK) telemetry transmitter for spacecraft telemetry applications. The unit accepts data at rates up to 3.2 Mbps per channel (uncoded) and employs a GaAs SSPA to generate 3 Watts of (nominal) RF output power. Contact Business Development and request a data sheet

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

Model T-715 is a 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 than 5 lb. 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

Model T-719 is a 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. SSPA delivers 5 Watts EOL at the output of a transmit filter that limits emissions. Contact Business Development and request a data sheet
