Talk on GPS Technology


SIT SEMINAR ROOM (ground floor SIT bldg), Wednesday Aug 24th, 4pm


GPS: An Indispensable Technology


Prof. Pratap Misra, Tufts University


GPS in many ways is like the Internet. Both are gifts of the U.S. Department of Defense (DoD) to the civil community. Both continue to transform the way we do ordinary, everyday things as individuals and society, delivering wide-ranging economic and social benefits far beyond anything their designers could have dreamt of. And, of course, the Internet now plays an important role in newer GPS applications.

Operational for about 20 years, GPS is now used by over 1 billion people, mostly as a receiver-on-a-chip built into their smart phones. GPS has also raised our expectations: we now demand meter-level positioning capability anytime and anywhere, including indoors. And, inevitably, success brings imitators: GPS-like systems are under development in Russia, Europe, China, Japan, and India.

This talk will focus mostly on the principles behind the operation of GPS and the technologies required to realize a global radio-navigation system based on them.

Speaker's Bio:

Pratap Misra, a member of the first batch of students to graduate from IITK, has worked in the field of navigation satellites for 25 years starting with a project at MIT Lincoln Laboratory to combine measurements from GPS and GLONASS, the Soviet answer to GPS, to improve navigation for civil aviation. He is a coauthor with Professor Per Enge of Stanford University of a widely used graduate-level engineering textbook on GPS.

Misra is a Fellow of the Institute of Electrical and Electronics Engineers (IEEE). He is also a Fellow of the Institute of Navigation (ION), which honored him in 2014 with the Kepler Award "for sustained and significant contributions to the development of satellite navigation."
