Navigation and position fixing

Perth, WA

I'm an expert in positioning and navigation using Global Navigation Satellite Systems (GNSS). I'm now a member of the GNSS-SPAN Group at Curtin University in Australia, and working on the Precise Orbit Determination (POD) of CubeSats and its applications in space and earth sciences. My future bright goal is to implement POD using artificial intelligence and machine learning algorithms. I'm working hard and dreaming every day to see my idea is running on a smart constellation in space because I always say: "Try hard and wisely; Dreams will come true."
