Wireless Without Batteries — The Introduction

Posted on August 3, 2018 Written by Gregory Durgin

In the Spring term of 2017, I taught a graduate-level class at the Georgia Tech campus in Shenzhen, China.  I have a set of rough videos for 19 lectures related to the topics of low-powered sensing, radio communications, and energy-harvesting.  Below is the introductory lesson, along with the corresponding readings.

WWB01:  Introduction; Computation and Power Trends
Paper:  J.G. Koomey, S. Berard, M. Sanchez, H. Wong. “Implications of Historical Trends in the Electrical Efficiency of Computing”.  IEEE Annals of the History of Computing.  Jul-Aug 2011. pp 46-54.
Reading:  WWB Introductory Notes and Perspectives

FemtoSats Project

Posted on August 1, 2018 Written by Gregory Durgin

If you would like to orient yourself to the ever-shrinking world of small satellite missions, here is an excellent class project by Alex Akins on the design of a femtosatellite mission. From the report:

While every satellite mission begins with a different idea, all of them share a common con- straint: cost. As the mass of the satellite increases with more instruments and larger struc- tures, the cost of ferrying the mission from Earth to Low Earth Orbit (LEO) increases. Cost also increases with semimajor axis of the operating orbit. While private companies such as SpaceX strive to reduce launch expenses, the fact remains that it costs multiple thousands of dollars per kilogram to insert satellites into orbit. For certain mission profiles, small, lighter satellites may be an appealing option.

New ECE 4370/1 Antenna Engineering Home Page

Posted on July 18, 2018 Written by Gregory Durgin

As the old prop group site slowly migrates and integrates into the new wordpress site, we will be transferring course content over. Today, we’d like to introduce the new course site for managing content in our antenna engineering courses. This includes the lecture course ECE 4370 Antenna Engineering and the optional, concurrent laboratory course ECE 4371 Antenna Engineering Laboratory. Both courses will be offered this fall term.

GPS III and the “Competition”

Posted on July 16, 2018 Written by Gregory Durgin


Another “course refresh” video from Shenzhen 2017 discussing the emerging GPS-III standard and some of the other up-and-coming Global Navigation Satellite Systems (GNSS).  This lecture is a follow-on to lectures on basic GPS operation (courtesy our friend Prof. Paul Steffes) and Positioning Errors in GPS.
