Positioning with Single-Anchor Indoor Navigation System Using Phase Measurements

The development of indoor navigation systems is an urgent task of our time. Such systems find their application in various fields: first of all, these are security systems and monitoring of industrial premises. Current trends in the development of such navigation systems are aimed at improving the accuracy of navigation support, as well as reducing the cost of such systems. The main reason for the high cost of indoor navigation systems is the infrastructure of the system, which usually consists of a system of several supporting transceiver beacons and wearable user tags. Often, applications and specific objects require both a large number of wearable tags and a large number of reference radio tags. In the first case, it is difficult to do anything, since each user must be positioned. If we talk about the beacon system, then it is possible to reduce it to one beacon with several antenna elements (by the type of antenna array). This article presents the development of an indoor navigation system that uses a single ultra-wideband anchor.
