The EIGER (Design of Enhanced Reliable GNSS/UWB Personal Navigation Devices) project was focused on the design of a propagation environment-independent hybrid GNSS/UWB-based standalone Personal Navigation Device that is able to meet the today’s most stringent Location Based Services requirements in both outdoor and indoor situations.
The EIGER project was carried out from 1.11.2013 to 30.10.2015 by a consortium including the following participants:
- ECLEXYS SAGL, Switzerland
- Warsaw University of Technology (IOT Systems Research Group)
- SAPHYRION SAGL, Switzerland
- POLE STAR SA, France
- Laser Navigation srl, Italy
Eiger system architecture
The general idea behind the project was to develop a system enabling sustained navigation in both outdoor and indoor environments using GNSS and UWB-based systems. In the implemented concept the personal navigation device is composed of an UWB positioning module and a smartphone or a tablet.
The IOT Systems Research group was responsible for design and implementation of the UWB-based part of the system (both localization module and system infrastructure). The proposed system is Time Difference of Arrival based and is wirelessly synchronized using a novel consecutive transmission-based method. The developed system is of unilateral architecture. The anchors periodically transmit UWB packets, which are then received by the localized devices. The devices measure their reception time and localize themselves using a TDOA-based algorithm. Such approach allows for an independent navigation and easy system scaling.
Aside from the anchor node modules and localization devices, the IOT Systems Research Group developed firmware and software applications supporting UWB localization system deployment and testing. The developed modules and software were a basis for development of the final positioning module integrating GNSS and UWB parts by Saphyrion SAGL
Project funding:
The research leading to these results has received funding from the European Union’s Seventh Framework Programme managed byREA– Research Executive Agency http://ec.europa.eu/-research/rea (FP7/2007 2013) under Grant Agreement No. 315435 and was financed from the funds for science in 2015 allocated to the implementation of an international co-financed project by the Ministry of Science and Higher Education.
