Project: Metrology for long distance surveying

Many tasks in science and engineering require accurate surveying. Surveillance networks help assess the risk of possible landslides, sinkholes or other tectonic activity, and ensure the safety of local populations and industrial facilities from potential natural disasters. Sea levels are also monitored for both climatologic studies and disaster prevention. Currently, networks of monitoring devices must measure large distances, of up to several kilometres, with uncertainties of one millimetre or below. Two different measurement techniques are commonly used: optical distance measurement and Global Navigation Satellite Systems (GNSS). However, neither technique can provide traceability to the metre, with the required level of accuracy. This project will develop optical devices that can measure distances of up to one kilometre in air with an uncertainty of 10–7, as well as improving our understanding of different sources of uncertainty for devices based on high-accuracy GNSS. The results will feed into two different test measurement systems in Sweden and Finland.
