WNCG professor Todd Humphreys and postdoctoral fellow Peter Iannucci of the Radionavigation Laboratory have developed a system using the constellation of SpaceX satellites to potentially deliver a low-cost, more accurate, and highly secure alternative to GPS. Their work was recently featured in the MIT Technology Review:

WNCG professor Todd Humphreys has received the Institute of Navigation’s (ION) “highest honor.” Humphreys was elected to the membership rank of Fellow at ION’s International Technical Meeting in January. He is one of only three recipients of the honor for 2020. Humphreys’ election cited his “significant and fundamental contributions to PNT security and precise GNSS positioning for the mass market, and for dedication to GNSS education and outreach.”

Researchers at the Cockrell School of Engineering at The University of Texas at Austin have achieved a milestone in modern wireless and cellular telecommunications, creating a radically smaller, more efficient radio wave circulator that could be used in cellphones and other wireless devices, as reported in the latest issue of Nature Physics. The new circulator has the potential to double the useful bandwidth in wireless communications by enabling full-duplex functionality, meaning devices can transmit and receive signals on the same frequency band at the same time.

A team of researchers in the Department of Electrical and Computer Engineering at The Unversity of Texas at Austin (UT ECE) led by Prof. Andrea Alù has built the first-ever circulator for sound. The team’s experiments successfully prove that the fundamental symmetry with which acoustic waves travel through air between two points in space (“if you can hear, you can also be heard”) can be broken by a compact and simple device.
