Working Group 4.1.1

Multi-Sensor Systems

Chair: Allison Kealy (Australia)
Vice-Chair: Günther Retscher (Austria)

This group is a joint working group between IAG and FIG. It focuses on the development of shared resources that extend our understanding of the theory, tools and technologies applicable to the development of multi-sensor systems.

The major focus of the Working Group is on:


  • Performance characterization of positioning sensors and technologies that can play a role in augmenting core GNSS capabilities


  • Theoretical and practical evaluation of current algorithms for measurement integration within multi-sensor systems


  • Development of new measurement integration algorithms based around innovative modeling techniques in other research domains such as machine learning and genetic algorithms, spatial cognition etc.


  • Establishing links between the outcomes of this WG and other IAG and FIG WGs (across the whole period)


  • Generating formal parameters that describe the performance of current and emerging positioning technologies that can inform IAG and FIG members


Specific projects to be undertaken include:


  • International field experiments and workshops on a range of multi sensor systems and technologies


  • Evaluation of UAV capabilities and the increasing role of multi-sensor systems in UAV navigation.


  • Investigation of the role of vision based measurements in improving the navigation performance of multi-sensor systems.


  • Development of shared resources to encourage rapid research and advancements internationally.
