MUSCAT: The National Centre for Measurement and Calibration has launched a new programme to establish a Gulf network for absolute gravity measurements aimed at improving laboratory accuracy and strengthening technical integration among GCC countries.
The three-day programme, organised by the centre under the Ministry of Commerce, Industry and Investment Promotion, focuses on building a precise regional network for terrestrial gravity measurements using the high-precision FG5-X instrument in accordance with international standards.
The initiative seeks to connect gravity measurements across GCC countries to the International System of Units (SI), supporting more accurate calibration and measurement systems.
The programme includes workshops and specialised lectures covering the role of gravity values in measurement and calibration, calculation mechanisms using the FG5-X instrument, factors affecting accuracy and the importance of gravity reference points in geological surveys.
Participants are also reviewing and analysing terrestrial gravity measurement results as part of efforts to exchange technical expertise and strengthen scientific cooperation among GCC member states.
Ahlam bint Masoud al Marhoubi, Head of the National Metrology Laboratory at the Directorate-General of Standards and Metrology, said the initiative forms part of wider Gulf efforts to strengthen national infrastructure for reference measurements and reduce uncertainty in physical quantities linked to gravity, including weight, pressure, torque and viscosity.
She said the network would support national laboratories, improve technical capabilities and align national standards more closely with international measurement systems.
Al Marhoubi added that the project is expected to support industrial, research and regulatory sectors by providing a reliable reference for absolute gravity values, enhancing the quality of measurements and calibration processes across the GCC.
Faiza bint Mohammed al Mushrifi, Director of the National Centre for Measurement and Calibration, described the initiative as a major step forward for the Sultanate of Oman’s national laboratory capabilities due to the high precision of the FG5-X instrument at microgal measurement levels.
She said the network would contribute to the establishment of national reference points supporting geodetic coordinate systems, surveying activities, major engineering projects and geophysical research applications.
According to Al Mushrifi, the next phase will involve preparing measurement sites, conducting specialised training programmes for national personnel and coordinating with relevant authorities to determine precise coordinates and elevation levels for the selected locations.
She noted that the project would enhance Oman’s position in advanced measurement and calibration fields while supporting broader Gulf efforts to unify standard references and strengthen technical cooperation in metrology and scientific measurements.
A specialised technical team from the National Centre for Measurement and Calibration is participating in the programme in cooperation with its Omani counterpart. — ONA
