2019–2022 Improving the traceability chain in geodetic length metrology
Novel scientific concepts and field-capable devices are needed for SI-traceable large-scale dimensional measurements, e.g. in monitoring changes in sea level, retreating ice sheets and long-term tectonic motion.
Project develops a robust and accurate frame of reference for reliable geodetic monitoring.
WP1: Innovative instrumentation for dimensional metrology in geodesy
WP2: Earth-bound SI-traceable validation of SLR and GNSS
WP3: Enhanced local tie metrology at GGOS space-geodetic core stations
VTT MIKES develops a field-capable spectroscopic long-range thermometer, since accurate air temperature measurements are crucial in improving distance measurement uncertainty.
