Satellite Geodesy and Navigation (SGNL)

The mission of the Satellite Geodesy and Navigation Group (SGNG) is to bring improved accuracy and robustness to all sgnl-1.jpg

positioning applications, whether in Geomatic Engineering, Navigation, Earth Sciences or Location-based Services. Our research interests include precise orbit and clock modelling, multi-sensor navigation and positioning, exploiting new global navigation satellite system (GNSS) signals and constellations, applied geodesy and multipath mitigation.

The research work in geodesy and navigation consists of finding new solutions to challenging positioning problems, as well overcoming geodetic challenges that result from the ubiquity of positioning systems. Key research themes include advanced orbit and clock modelling, novel precise positioning applications, robust multisensor positioning and navigation, and coordinate systems such as VORF and SnakeGrid.

  • SnakeGrid: The development of low-distortion 2D coordinate systems for engineering projects such as railways that extend over hundreds of kilometres of the Earth’s surface.
  • Vertical Offshore Reference Frames (VORF): The development of high resolution transformation surface models to provide the link between GPS/GNSS positioning and offshore reference levels such as Chart Datum and Mean Sea Level.
  • Robust Positioning and Navigation: A series of projects focused on novel techniques for improving the performance of GNSS and multi-sensor navigation and positioning systems under challenging reception conditions, such as in dense urban areas and under jamming.
