A unique feature of the roof based laboratory of the Nottingham Geospatial Building is a fixed track designed for dynamic positioning system research and testing.
Equipped with a custom designed remote controlled locomotive that has been designed to carry a navigation grade POSRS inertial unit the track is a total of 120m in length with a 7¼” (184.15mm) gauge. It provides a multi-sensor platform with the capability for sub-centimetre level accuracy for developing and testing integrated navigation and positioning solutions
