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.

CR-313 S-Band Configurable Digital Command Receiver

00Model CR-313 is an 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, Residual Carrier Direct Modulation as well as USAF SGLS (Space-Ground Link System).

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

00Model T-710(B) is a low-power light-weight (4.5 lbs) factory selectable (BPSK/QPSK) telemetry transmitter for spacecraft telemetry applications. The unit accepts data at rates up to 3.2 Mbps per channel (un-coded) and employs a GaAs SSPA to generated 3 Watts of (nominal) RF output power.

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-721 X-Band UA-QPSK Telemetry Transmitter

00Model T-721 is a narrowband X-band transmitter optimized for low rate telemetry downlinks. This unit offers unbalanced QPSK modulation with a variable I/Q power ratio. This allows the spacecraft designer to utilize independant I and Q channels with different data rates. The 3W output spectrum is compliant with NTIA specifications and can be centered anywhere in the 8.0 to 8.4 GHz band.
