April 2023: “A vehicular pose estimation technique is presented that tightly couples multi-antenna carrier-phase differential GNSS (CDGNSS) with a low-cost MEMS inertial sensor and vehicle dynamic constraints. This work is the first to explore the use of consumer-grade inertial sensors for tightly coupled urban CDGNSS, and first to explore the tightly coupled combination of multi-antenna

March 2023: “Todd Humphreys began studying electrical engineering at Utah State University with the intention of becoming a patent lawyer. His career path changed, however, thanks to a professor who told him he had the heart of an engineer. […] A third-generation Aggie, Humphreys completed his bachelor’s and master’s degree in electrical engineering from Utah
March 2023: A paper written by the RNL’s Zach Clements titled “Carrier-phase and IMU based GNSS Spoofing Detection for Ground Vehicles” got published in GPS World. The summary from GPS World is “we look at how carrier-phase measurements combined with those from an inertial measurement unit can guard against a deliberate attack on an automated
