Telemetry Receivers / Demodulators & Downlink: RF, IF & Sub-Carrier

A full line of board and box level telemetry receiver products are offered. Our state-of-the-art 3rd generation telemetry receiver design is highly flexible and provides comprehensive multi-link support for satellite and flight test ground station applications in a fully integrated package. Our telemetry receiver design features FPGA based signal processing and software defined radio technology in the form of digital telemetry receivers, waveform & signal processors. A variety of tunable frequencies (RF, IF & Subcarrier), configurations (Single, Dual, Quad) and waveforms (AM, FM, PM, DPM, PCM/FM, B/O/SO/AU/QPSK, GMSK, FM/PSK, PM/PSK, SGLS, ARTM Tier 0, 1 & 2 ) are available with standard data rates from 40Mbps down to 5bps.

Due to its integrated FPGA technology this telemetry receiver product includes optional pre/post diversity combining, embedded bit synchronizers, independent frame synchronizer pattern detectors and a variety of FEC options including but not limited to Viterbi, Reed-Solomon (CCSDS) and LDPC. Options are also available that support Gig-Ethernet chapter 10 output of data directly from the telemetry receiver module, IRIG time input and an encapsulated data/signal quality output for the diversity combining best source selector. This state-of-the art telemetry receiver product line provides a compact, cost competitive, flexible solution to a wide variety of communications link scenarios.
