High-Resolution Indoor RF Ranging
نویسندگان
چکیده
Our recently developed indoor RF Ranging technology allows new levels of accurate indoor localization based on carrier-phase measurements. Measuring the phase difference over multiple frequencies, and combining it with a novel multipath angle-of-arrival differentiation technique, we achieving accuracies of a few centimeters in direct line of sight, and a few tens of centimeters in non-direct line of sight. Similar to GPS satellites, our system requires self-localizing multi-antenna base stations as a infrastructure and anchor points. ! Keywords—RF Ranging, Localization

Radio Frequency (RF) Time-of-Flight Ranging for Wireless Sensor Networks
Position information of nodes within Wireless Sensor Networks (WSNs) is often a requirement in order to make use of the data recorded by the sensors themselves. On deployment the nodes normally have no prior knowledge of their position and thus a locationing mechanism is required to determine their positions. In this paper, we describe a method to determine the point-to-point range between sens...
متن کاملPerformance of a Precision Indoor Positioning System Using a Multi-Carrier Approach
System performance aspects of the Multi-carrier Ultrawideband (MC-UWB) approach to positioning are presented. This system implements a wideband or ultrawideband ranging signal in the frequency domain, retaining the frequency coordination and spectral allocation benefits of conventional systems while including signal characteristics which permit resolution of multipath signals in indoor or other...
متن کاملDemo Abstract — PolyPoint: High-Precision Indoor Localization with UWB
We demonstrate PolyPoint, a high-fidelity RF-based indoor localization system that achieves 28 cm accuracy indoors and tracks a fastmoving quadcopter with only 56 cm average error. PolyPoint uses ultra-wideband signals to achieve high precision RF time-of-flight estimates between nodes. To further improve accuracy, PolyPoint exploits two forms of diversity: frequency diversity, which leverages ...

متن کاملNextechs Indoor Positioning System
The Nextechs Indoor Positioning System (NIPS) is an UWB based system for high resolution, high accuracy, 3D location of objects indoor. The system consists of an infrastructure of fixed, active objects called NODES that perform ranging measurements with the objects that are to be located, called TARGETS. Signal time of flight (tof) from nodes to targets is measured in order to compute distances...
