Fergus Noble graduated in 2011 with an MSc. in Physics from the University of Cambridge, UK. Whilst at Cambridge he spent most of his spare time working on an 100km amateur rocket attempt which led to his frustration with available GPS systems. After graduating, he moved to California to work for Joby Energy on GPS systems for high-altitude wind turbines before co-founding Swift Navigation with Colin Beighley and Henry Hallam to work on a new open-source GPS receiver. He is also a co-maintainer of libopencm3, an open-source peripheral library for ARM Cortex-M based microcontrollers and creator of Plot-o-matic, an open-source tool for quickly visualising real-time data streams. https://github.com/fnoble Colin Beighley graduated from the University of California at Santa Cruz in 2010 with a BS in Electrical Engineering. He worked at Joby Energy in Bonny Doon, California, before co-founding Swift Navigation with fellow GPS hackers Fergus Noble and Henry Hallam. He is the creator of softgnss_python, an open-source GPS/GNSS post-processing library.
