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

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
