| Zusammenfassung | Long-term comparability and independence of measurement devices in general require tight traceability to the SI definition of the underlying unit. This requirement is difficult to fulfill in the metrology of distances at the kilometre level. Even state-of-the-art methods are unable to secure traceability at an uncertainty level below 1 ppm. Therefore, in 2013, the European Metrology Research Programme (EMRP) decided to fund a joint research project (JRP) to develop novel technologies and explore methods to strengthen the traceability chain in surveying. The scientific work covers the two major technologies in distance metrology: Electro-optical and GNSS-based distance measurements (DM). In case of EDM, the main goal was to develop novel primary and transfer standards for the calibration of geodetic baselines with uncertainties well below 1 ppm. For this purpose, two approaches to inline refractivity-compensation were realized and verified against each other and state-of-the art standards on primary baselines. Additional optical methods were developed to rigorously quantify temperature gradients and the impact of turbulence on the optical measurement. Beyond, the potential of novel optical sources like fibre-based frequency combs for high precision length measurement was explored. In case of GNSS-based DM, several sources of uncertainty, like the influence of troposphere, or near-field and obstruction effects were investigated thoroughly, making use of facilities like common-clock fibre baselines, antenna calibration facilities, or novel test field designs. All measurement campaigns were jointly analyzed in search of a proposal of state-of-the-art good practice standards for high-accuracy DM and uncertainty considerations. The consortium also studied approaches to real-time 3D monitoring of the IGS/VLBI local tie vector at the geodetic fundamental stations of Onsala, Sweden and Metsähovi, Finland. The contribution is intended to provide an overview of major project results and to serve as basis for a discussion of length metrology challenges in surveying. |
