ILC investigation and in-field traceability using a high sensitivity & high mass geophone set

Following and in relation to the recently finalized EMPIR-infra AUV project, and in attempt to accommodate a raising interest and need globally for high level metrology in both the very Low Frequency range (VLF) and the Ultra Low Frequency range (ULF), an Inter Laboratory Comparison (ILC) has been initiated among 4 different National Metrology Institutes (NMIs)/Designated Institutes (DIs). The participating metrology institutes already have measurement capability (CMC) in the frequency range relevant for providing traceability to in-field vibration monitoring using geophones.
