The research carried in the UWB Systems Group mainly addresses development of UWB positioning systems and their applications.
The group activities cover:
- development of UWB signals generation and reception techniques,
- investigation of UWB propagation channel and its impact on localization results,
- development of UWB positioning systems hardware and software,
- development of positioning algorithms,
- design and investigation of transmission schemes in UWB positioning systems,
- data fusion algorithms combining UWB system results with other measurement results e.g. from inertial sensors, laser scanners and odometry systems.
Developed devices support two basic architectures:
- multilateral – i.e. architecture in which a tag being a source of signal is localized with a network of anchors/receivers
- unilateral – i.e. architecture in which the tag measures signals transmitted by anchors and calculates its own position
A set of nodes and tags for both positioning system architectures is shown in Fig .1
