                                                  Abstract

                                                  Navigation is a field that has been fascinating humankind for thousands of years and these pillars have been evolving with new technological advancements.  The current market in positioning and navigation is clearly dominated by GNSS. Besides being globally available, it provides the whole range of navigation accuracies at very low cost. It is also highly portable, has low power consumption, and is well suited for integration with other sensors, communication links, and databases.

                                                  At this point in the development of navigation technology, the need for alternative positioning systems only arises because GNSS does not work in all environments. Furthermore, there has been a constant push to develop navigation systems that are accurate, continuous and easy to afford. Needless to say that cost and space constraints are currently driving manufacturers of Guidance, Navigation & Control systems to investigate and develop next generation of low cost and small size navigation systems to meet the fast growing indoor navigation and location services market demands. Advances in inertial navigation and more specifically Micro-Electro-Mechanical Systems (MEMS) technology have shown promising light towards the development of such systems. MEMS are integrated micro devices or systems combining electrical and mechanical components whose size ranges from micrometers to millimeters. MEMS is an enabling technology and the MEMS industry has a projected 10-20% annual growth rate to reach 240 billion US$ market by 2016. Advances in MEMS technology combined with the miniaturization of electronics, have made it possible to produce chip-based inertial sensor for use in measuring angular velocity and acceleration. These chips are small, lightweight, consumes very little power, and extremely reliable. It has therefore found a wide spectrum of applications in the automotive and other industrial applications. MEMS technology, therefore, can be used to develop next generation Guidance, Navigation & Control systems that are inexpensive, small, and consume low power (microwatt). However, due to the lightweight and fabrication process, MEMS sensors have large bias instability and noise, which consequently affect the obtained accuracy from MEMS-based IMUs. This presentation will provide a state of the art and future trends of MEMS based navigation technology: possibilities, limitations and various design approaches. Some of the current developed and possible future system’s accuracy performance will be demonstrated through land/airborne vehicles and personal units’ tests.

He supervised and graduated over 60 Masters and PhD students. He is the recipient of many national and international awards including the ASTech “Leadership in Alberta Technology” Award the Association of Professional Engineers, Geologists, and Geophysicists of Alberta (APEGGA) Educational Excellence Award. He also received the Schulich School of Engineering Research Excellence Award, the Schulich School of Engineering Teaching Excellence Award, The UofC Student Union Teaching Excellence Award, and 4 times the departmental teaching award, 2 times departmental research excellence award, and the department of Geomatics Engineering Graduate Educator Award.    Dr. El-Sheimy was the president of Commission I on "Sensors and Platforms" of the International Society for Photogrammetry and Remote Sensing (ISPRS) from 2008 - 2012. He organized and participated in organizing many national and international conferences and chaired many conferences such as the USA Institute of Navigation Global Navigation Satellite Systems (GNSS).  Dr. El-Sheimy is currently a member of the Editorial Board of Journal of Survey Review, Journal of Applied Geodesy, and Coordinates. He served as a member of the Alberta Geomatics Group Board of Directors, Geoide NCE Board of Directors, and Technical Committee Member of the ASPRS Direct Georeferencing Committee. He commercialized a number of technologies through the University of Calgary Commercialization office which brings close to $3M of funds to the University of Calgary.
