Indoor Passive Positioning Technique using Ultra Wide Band Modules

The paper is aimed to Indoor positioning systems based on UWB technologies and passive positioning methods. There are a lot of commercial solutions, which are based on the same principles of communication. In our project an UWB system TREK 1000 was used, which simulated real indoor positioning system with real communication among anchors and tags. It was used of another device for passive positioning, which sniffed all the communication in system. This device calculated position of users in IPS without transmitting any signal. It was used just information received by other tags and anchors in indoor PAN, so this device is invisible for the system. Some experiments were made for verifying of theoretical results.
