High precision plug-and-play local positioning system using ultra-wideband transceivers

Semester Thesis, HS14 (10393/4)

Available positioning systems like GPS or vision-based systems have limitations in terms of accuracy, sampling rate and outdoor use. In this project a positioning system using novel ultra-wideband technology was implemented for applications where accuracy, lo- cal scale, cost and ease of setup is critical. The motivation of this work is to extend or even replace existing positioning solutions with miniaturized, standardized transceivers optimized for time of ight measurements of a wireless signal. These time measurements allow a precise distance estimation between two hardware nodes. In this project six self-contained ultra-wideband transceiver nodes were built using commercially available ultra-wideband transceiver chips. A two-way ranging application gathering distance mea- surements from the wireless communication was implemented. Finally, a multilateration algorithm was applied to a test case with a moving target to demonstrate the technology which can be applied in future for example to control autonomous sailing boats, race cars and energy-harvesting kites.
