EMRP – European Metrology Research

ProgrammeThree guiding principles:

• “Together we are stronger”:

− Cooperation: bundling of competence

• “Not everybody needs to do everything”:

− Coordination: definition and development of individual competence profiles,

perhaps concentration on certain areas of specialization

• “Harmonization and Cohesion”:• “Harmonization and Cohesion”:

− Strengthening metrological competence across Europe

• Legal basis: Article 185 Lisbon Treaty

• 200 mio. € by EU, 200 mio. € by metrology institutions

• Last call for proposals in 2013

• Successor programme EMPIR started 2014

EMRP SI Broader Scope

“The 2012 TP SI Broader Scope […] specifically addresses the development

of new advanced techniques for providing traceability of measurement

results to the users of metrology services.”results to the users of metrology services.”

Objectives of JRP SIB60

… to improve the traceability and to reduce the uncertainty of long-distance

metrology and thus to improve the metrological and technological basis of

surveying, geodesy and earth science.

• EDM with U of 10-7 L up to 1km in air

• U of GNSS-based distance meters to 1 mm

• local ties at geodetic fundamental stations:

U reduced to 0.1 mm

• fs-based distance metrology over several hundred metres

• provision of rigorous calibration procedures

Supported by

The SIB60 „Metrology for long distance

surveying“ project

• X

• unites 15 partners (NMIs, universities)
