No GPS, No Problem: Next-Generation Navigation

A team of researchers at UC Riverside has developed a highly reliable and accurate navigation system that exploits existing environmental signals such as cellular and Wi-Fi, rather than the Global Positioning System (GPS).

The technology can be used as a standalone alternative to GPS, or complement current GPS-based systems to enable highly reliable, consistent, and tamper-proof navigation. The technology could be used to develop navigation systems that meet the stringent requirements of fully autonomous vehicles, such as driverless cars and unmanned drones.

Led by Zak Kassas, assistant professor of electrical and computer engineering in UCR’s Bourns College of Engineering, the team presented its research at the 2016 Institute of Navigation Global Navigation Satellite System Conference (ION GNSS+), in Portland, Ore., in September.

The two studies, “Signals of Opportunity Aided Inertial Navigation” and “Performance Characterization of Positioning in LTE Systems,” both won best paper presentation awards.

Brown Speaks on Incentives in HIV Research

Brandon Brown, an assistant professor in the Center for Healthy Communities in the UCR School of Medicine, attended a conference in Washington, D.C., on Oct. 6-9, 2016, hosted by the American Society for Bioethics and Humanities, in which he talked about incentives in HIV research.

In his presentation, titled “Working with Stakeholders to Build a Resource for Ethical Decision Making for Incentives in Research,” Brown discussed how incentives are used in research, how an incentive resource can be useful, and how this resource might be developed.

“In planning a new human subjects research study, there is no simple way to find what incentives have been provided in similar studies in the past, nor guidance on what incentives one should provide,” Brown said. “It is also unclear who should make decisions on the appropriate incentives. While there are several stakeholders – study participants, the principal investigator, the sponsor, the institutional review boards, ethicists – few actually provide input on what incentives are inadequate, appropriate, or excessive.”
