At the ION GNSS+ 2021 conference in St. Louis, Missouri, the annual meeting of the Satellite Division of the Institute of Navigation, Brad Parkinson bestowed Lakshay Narula with the division’s Bradford W. Parkinson Award for his Ph.D. thesis “Towards Secure & Robust PNT for Automated Systems” at the University of Texas at Austin. The award honors Parkinson, known as the “father of GPS,” for his leadership in establishing both GPS and the Satellite Division of the ION. Narula is now an applied scientist at Amazon Lab126 in Sunnyvale, California, where he researches robust navigation and state estimation methods for robots, from self-driving cars to aerospace applications.
