Indoor Localization and Positioning through Signal of Opportunities

Abstract

An indoor positioning system using a network of synchronized low cost battery powered sensor nodes utilizing ultra wideband impulse radio technology is described. The system components such as battery powered beacon transmitters and receivers to be utilized in the sensor nodes are developed. A receiver array for the positioning of the user is also developed. The receiver array is powered through a USB interface to a notebook computer and the digitized data are processed in MATLAB through the same interface. A self calibration algorithm for the positioning of sensor nodes is presented and experimentally tested. Preliminary tests show good ranging accuracy in the decimeter range.
