As part of his recent paper for the IEEE/ION PLANSx conference, Lakshay Narula published an extensive dataset for urban positioning, called TEX-CUP: The University of Texas Challenge for Urban Positioning.

"Mass-market precise GNSS positioning is being researched now more than ever", Lakshay says. "To make progress as a research community, we need to evaluate new techniques on a shared dataset, and this dataset must be challenging and representative of typical urban driving. Self-driving car datasets available today do not provide raw IF GNSS data, or even the raw pseudorange and carrier-phase observables. With the release of TEX-CUP, we're hopeful that the precise positioning community will finally have a shared benchmark dataset. As we add data from many major cities around the world, we believe TEX-CUP will be the go-to dataset for precise GNSS evaluation."

We look forward to seeing what the community achieves with Lakshay's dataset!

This article from GPS World reports on GPS spoofing discovered in Iran. It references some of Dr. Humphreys's early work in GPS spoofing.

The Radionavigation Lab's work in GNSS interference detection was featured on the cover of Inside GNSS, a magazine dedicated to global navigation systems. Click here to read the article from Inside GNSS.

In 2017, the Radionavigation lab placed a custom software defined receiver onboard the International Space Station as part of a larger effort to study GNSS signals in the low Earth orbit environment. Over the two year study, multiple sources of GNSS interference were identified by analyzing data from the receiver. This work was done by Radionavigation Lab members Matthew Murrian (lead author), Lakshay Narula, and Todd Humphreys. Brady O'Hanlon from MITRE Corporation and Scott Budzien from the U.S. Naval Research Laboratory were also collaborators on the project. Congratulations to the authors!

Admiration for GPS runs high among RNL alumni, as witnessed by K. Wesson's new license plate!

The Institute of Navigation presented awards at their International Technical Meeting in January. These recipients are affiliated with the Radionavigation Laboratory:

  • Dr. Zaher (Zak) Kassas (left) is a former member of the lab and current professor at the University of California, Irvine. He won the 2019 Institute of Navigation Thurlow Award "for foundational work in the theory and practice of exploiting signals of opportunity for accurate and reliable positioning, navigation and timing."

  • Dr. Todd Humphreys (center) was elected as a 2020 ION Fellow "for significant and fundamental contributions to PNT security and precise GNSS positioning for the mass market, and for dedication to GNSS education and outreach." See articles from GPS World and the Cockrell School of Engineering.

  • Dr. Ramsey Faragher (right) is the CEO of Focal Point Positioning and a close friend of the lab. He was awarded the 2019 Per Enge Early Achievement Award "for outstanding innovations in mobile positioning and navigation, and in particular for pioneering the revolutionary SuperCorrelation technology." See this article from The Royal Society about his collaboration with Dr. Humphreys.
