Position and attitude determination of moving platforms or subjects is the main-stream of the lab research activity. The laboratory expertise in algorithm development for real-time or post-mission positioning have been applied to precise trajectory determination of land or airborne vehicles and pedestrians. We make use of satellite based (GPS, Glonass, Galileo) positioning, inertial sensors, magnetic sensors, imagery and networked based positioning via Ultra-wide band or 802.x technology. Most recent focus is in the developing of navigation system that can operate accurately and robustly even in the absence of external (GPS, Glonass, Galileo) positioning means. Developing visual and Vehicle Dynamic based Navigation schemes that utilise both filtering and machine learning based algorithms and approaches
Particular focus is give to the following areas:
- GNSS and INS integration and filtering algorithms
- GNSS free (Vehicle Dynamic and Visual) Navigation schemes
- Error modelling and estimation methods
