My research interests lie at the intersection of satellite navigation receiver technologies and the application of navigation satellite signals for remote sensing of the space environment, atmosphere, and Earth surface. My research lab develops advanced algorithms to enable navigation in urban and indoor environments, under interference conditions, and during space weather activities. We also study the signatures of disturbances on radio waves propagating through the ionosphere, the atmosphere, and reflections off Earth surface to monitor and study the environment. During the past decade, we have deployed a worldwide network of software-defined radios to monitor radio wave disturbances. We work with signals transmitted by navigation satellites and by sources that were intended for other purposes such as communication and networking. In addition, we research new signal designs that could be potentially used for next generation satellite navigation and remote sensing.

ASEN 6091 - Global Navigation Satellite System (GNSS) Receiver Architecture
Primary Instructor
-
Fall 2019
Investigates the overall architecture of satellite navigation receivers: including both the analog radio frequency conditioning (antenna to the analog-to-digital converter) and the various signal processing algorithms. Such treatment of the operation of the receiver will provide insight into the trade-offs that go into GNSS as well as the more broad generic spread spectrum receiver design. Recommended prerequisite: ASEN 5090.
