Title：Global positionging System -Research and Applications
Reporter：Prof. P.T. Jayachandran is the Chair of the Physics at the University of New Brunswick and is the Principal Investigator of the Canadian High Arctic Ionospheric Network (CHAIN). CHAIN is a network of 25 high-data rate specialized Global Positioning System (GPS) receivers and 6 High-Frequency (HF) radars (ionosonde) that are being operated continuously for Arctic Ionospheric monitoring. His research focus is on the Solar Wind-Magnetosphere-Ionosphere (SW-M-I) interaction and its effect on modern communication and navigation systems. He has published over 100 papers in refereed scientific journals. He is the current Chair of Commission G&H of the International Union of Radio Science (URSI) Canadian National Committee. He is also a member of the Canadian Committee of Antarctic Research (CCAR). He served on many Canadian and international committees and advisory boards. He is also review panel member of many granting agencies and reviewer for many scientific journals.
Abstract：Global Positioning System (GPS), a Global Navigational Satellite System (GNSS) has applications in many areas. It also contributed to fundamental research in many fields such as ionospheric Physics and contributed to our improved understanding of many fundamental processes in the Sun-Earth system. This talk will outline the three segments of the GPS system, basic principle behind the GPS system, sources of errors and ways to account for some of them, application areas, and will end with giving an outline of basic ionospheric research using GPS system.
