The Institute of Navigation presented Dr Mark Psiaki with the prestigious Johannes Kepler Award during the ION GNSS+ 2021 Conference on 24 September.

Dr Psiaki was recognized for setting a standard of rigor, clarity, and thoroughness in addressing key estimation and signal processing problems in PNT.
He originated the technique of bit-wise parallel RF signal processing for use in general-purpose processors. This enabler of software-defined GNSS led to the first space deployment of a fully software-defined GNSS receiver on a general- purpose DSP and to the widespread adoption of software-defined GNSS across the aerospace industry.

Additionally, Dr Psiaki’s real-time software radio expertise enabled the development of a spoofer cultivated in his research group. Dr Psiaki subsequently led the development of spoofing detection algorithms based on cross-correlation of unknown P(Y) codes and based on direction-of-arrival sensing.
