Relative Gravity Measurement Campaign during the 7th International Comparison of Absolute Gravimeters (2005)

Result description

Since the 1st International Comparison of Absolute Gravimeters (ICAG) and accompanying Relative Gravity Campaign (RGC) held at the BIPM in 1981, repeated ICAG-RGCs have been organized every four years. A total of 19 absolute gravimeters (AG) and 15 relative gravimeters (RG) participated in the 7th ICAG-RGC, which took place in 2005. This paper is the final report of the 7th RGC and replaces the preliminary results published earlier. It covers the organization of the RGC and the data processing, analysesRG behaviour, computes g, ?g and OAG (offset of AG) and discusses their uncertainties. In preparation for the BIPM key comparison ICAG-2009, a standard data-processing procedure has been developed and installed in the BIPM ICAG-RGC software package, GraviSoft. This was used for the final data processing.

    Relativní tíhová měření během 7. mezinárodního srovnávacího měření absolutních gravimetrů (2005)

  • Czech description

    První mezinárodní srovnávací měření absolutních gravimetrů (ICAG) včetně doprovodné kampaně relativních gravimetrů (RGC) bylo organizováno v BIPM již v roce 1981. Následně byly kampaně ICAG-RGC opakovány každé čtyři roky. Sedmého ICAG-RGC, které se konalo v roce 2005, se celkem zůčastnilo 19 absolutních gravimetrů (AG) a 15 relativních gravimetrů (RG). Tento článek je konečnou zprávou sedmého RGC a nahrazuje předběžné výsledky publikované dříve. Článek zahrnuje organizaci RGC, výpočet dat, analýzu vlatností RG, výpočet rozdílů tíhového zrychlení, ofsetů AG a diskusi nejistot. Během přípravy klíčového porovnání BIPM ICAG-2009 byl vyvinut standardizovaný postup výpočtu dat a instalován v rámci software balíku BIPM ICAG-RGC, GraviSoft. Tento software bylvyužit již nyní k výpočtu finálních výsledků.
