Level 1: I create embedded real-time Global Positioning System receiver firmware and field programmable gate array designs for the UNSW Namuru series of GPS receivers.
Level 2: I customize the Namuru GPS receiver in order to allow it to be used in novel and custom applications, such as on-board small 2U/3U CubeSats and to allow the receiver to perform remote sensing.
Level 3: I develop hardware and software solutions to allow the Namuru GPS receiver to be employed applications such as high precision carrier phase navigation relative navigation, high precision timing, and GPS-reflectometry remote sensing.
Interest in engineering
Why did you get into engineering?
During high school, I discovered that my strengths were in mathematics and physics. I also had an interest in astronomy at the time. I selected Electrical Engineering and Computer Science because it allowed me to build on these strengths and interests, while at the same time equipping me for a real job on graduation.
What are your research goals?
My research goals are to push the envelope on what you can do with GPS technology, with my current focus being to develop low cost GPS solutions for low cost space missions. I'm also interested in GPS based timing, weak signal processing and interference mitigation.
What do people not understand about you do?
I have an industry-based background, which differs from that of your typical academic. I earned my Masters and PhD by undertaking part-time study, all while being employed full-time in a highly demanding job within a start-up company working on cutting-edge technology.
This background means that I focus on building products and technology, but doing it in such a way that it is practical and reliable. This is often significantly more challenging than most would expect, and often not appreciated by those who are not required to get real products working in the real world.
Advice for prospective engineers
Recall the words of John F Kennedy, " “We choose to go to the moon in this decade and do the other things. Not because they are easy, but because they are hard.” So, don't select the easy subjects, but rather choose the more difficult and challenging subjects. This will put you in a much better position for your engineering studies.
Once you graduate with your undergraduate degree, go out and get some experience before considering further study. This experience will enhance any additional study you might undertake afterwards and allow you put what you are learning into context.
Before joining Surveying and Geospatial Engineering (SAGE) at UNSW in 2010, I was a Principal Engineer at SigNav Pty Ltd, a start-up company based in Canberra, where I worked on GPS receiver firmware, algorithms and other aspects of GPS receiver design. This included cutting-edge applications such as weak-signal navigation and timing receivers intended for mobile handsets and femto-cells.
Before that, I worked for three years at Auspace Ltd as a Software Systems Engineer as a member of the team that developed Australia's first GPS receiver.
My first job following my graduation in 1990 was for the Department of Defence, where I worked for Naval Materiel at the Combat Data Systems Centre (CDSC) as part of the Test & Development Group.
