The Precise GNSS Positioning Technology & Applications Theme is a SNAP Lab research strengthA wide range of applications are investigated, including surveying, geodesy, structural monitoring, geo-referencing of moving platforms, support for robotics and machine guidance, and use in cooperative positioning in support of advanced intelligent transport systems (ITS) applications. All are characterised by the use of measurements, data processing algorithms & operational procedures that can deliver centimetre-level accuracy.

SNAP Lab research includes: measurement modelling & algorithm design; multi-GNSS systems; real-time carrier phase-based positioning; Precise Point Positioning & differential positioning; design of permanent reference station networks & protocols; and multi-sensor integration.
