Flexible, Autonomous X-band TT&C

Recently, we have been involved with the design of an ESA TRP-funded research project: Flexible, Autotomous TT&C, (“FAT”) in collaboration with Zelinda (Ireland) Ltd and Honeywell Aerospace, taking the concept to TRL4 by building a breadboard. The FAT employs advanced DSP techniques to enable it to autonomously detect the modulation scheme and data rate of uplink transmissions in deep space research (DSSR), Earth Exploration (EES) and Near Earth Space Research (NESR) configurations. Adrian led the project whilst still working at Honeywell, developing the user requirements, equipment requirements and the overall architecture for an X-band configuration of the FAT. Later in collaboration with Zelinda, Adrian developed the FPGA designs for the autonomous carrier acquisition and Direct Sequence Spread Spectrum acquisition modules in MATLAB/VHDL and the application control software written in Java.
