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.
