T19: Indoor Geolocation Systems

Presenter: Ilir Progri, Giftet Inc.


The goal of this course is (1) to introduce pseudolite geolocation systems; (2) to classify the state of the art geolocation systems; (3) to identify the issues with the state of the art indoor geolocation systems; and (4) to propose and assess three Giftet Inc. pseudolite indoor geolocation systems.  It is assessed that the current GPS and GLONASS signal structures are inadequate to overcome two main design concerns; namely, (1) the near-far effect and (2) the multipath effect.  We propose three Giftet Inc. indoor geolocation systems as alternative solutions to near-far and multipath effects which are (1) C-CDMA, (2) OFDMA, and (3) MC-CDMA pseudolite indoor geolocation systems.  Each system is researched, discussed, and analyzed based on its principle of operation, its transmitter, the indoor channel, and its receiver design and issues associated with obtaining an observable to achieve indoor navigation.  Our assessment of these systems concludes the following.

First, a C-CDMA indoor geolocation system is a potential candidate for indoor positioning, with data rate up to 3.2 KBPS, pseudorange error, less than to 2 m and phase error less than 5 mm and overall to provide centimeter level position and velocity accuracy 99.9% of the time. Second, an OFDMA indoor geolocation system is another potential candidate with a totally different signal structure than the C-CDMA indoor geolocation systems.  Third, a MC-CDMA indoor geolocation system is a potential candidate to achieve centimeter level position and velocity performance accuracy 99.999% of the time and data rate up to 5 MBPS.
