Precise GPS allows automated cars to know thier own position with a high degree of accuracy, which is imperative for keeping a car in its own lane. Take a look at our latest papers on the topic:

Low-cost Precise Positioning for Automated Vehicles

Researchers at UT are discovering ways to make centimeter-accurate GPS affordable, reliable, and marketable, with some exciting possibilities for consumers. Take a look at our latest papers on the topic: 

A Dense Reference Network for Mass-Market Centimeter-Accurate Positioning

Advanced Techniques for Centimeter-Accurate GNSS Positioning on Low-Cost Mobile Platforms

The goal of the Machine Games project is to make drones a part of everyday life. Drones will use cm-accurate positioning service enabled by concurrent research at UT Radionavigation Lab. Take a look at our latest paper on the topic:
A Dense Reference Network For Mass Market Centimeter Accurate Positioning

Dr. Humphreys delivered a keynote presentation in Sydney, Australia at the 2016 Workshop of the International GNSS Service. His presentation focused on how reference networks and mobile devices will have to change to support precise positioning for the mass market. All IGS Workshop presentations can be found at

In November, 2015, Dr. Mark Psiaki from Cornell University gave a presentation on GNSS spoofing and spoofing mitigation at the International Symposium on Navigation and Timing, ENAC Toulouse, France. This talk features the collaboration on GNSS security research between Mark's research group at Cornell University and the UT Radionavigation Laboratory. It is the most comprehensive presentation on the topic of GNSS security to date, and serves as a verbal companion to Psiaki's and Humphreys's 2016 IEEE Proceedings paper "GNSS Spoofing and Detection"

Dr. Todd Humphreys delivered a seminar on Low-Cost Centimeter-Accurate Mobile Positioning at the Roadway Safety Institute at University of Minnesota. This presentation focused on techniques for reducing the initialization time for centimeter-accurate positioning on mobile devices. It further examined technical and market prerequisites for improved safety for semi-autonomous and autonomous vehicles, globally registered augmented and virtual reality, and crowd-sourced three-dimensional mapping.

Using software developed at RNL and a low-cost GPS antenna, we demonstrate position tracking of a virtual reality headset to centimeter accuracy, in real time.
