ABSTRACT

At the moment in Romania there are a total of more than 7000 individuals and legal entities authorized by ANCPI (National Agency for Cadastre and Land Registration) for geodetic, photogrammetric, cartographic, cadastre and land registration works [4]. According to ANCPI standards there are regulated minimum technical conditions necessary for authorization including types and performances for geodetic and topographic equipments. At the national level the State Legal Office of Legal Metrology (BRML), which is in charge of the National Institute of Metrology (NIM) acts as a representative institution for metrology and ensures the accuracy and consistency of measurements performed in different public activity areas. NIM it is the official institution dealing with the realization, preservation and dissemination of units in Romania, in accordance with the requirements of Mutual Recognition Arrangement of National Measurement Standards and National Calibration Certificates issued by national institutes of metrology [6]. BRML includes in its structure the Market Supervision Inspection Service and has primary responsibility for ensuring the realization of national market surveillance activities [5]. BRML activity it is based on government decisions No. 711/2015 establishing the conditions for placing on the market of measuring instruments and No. 1660/2005 regarding the approval of legal metrology instructions. One of the most spreaded geodetic technology it is the GNSS technology including GNSS receivers and antennas. Recognizing the need for specifications on best practices for GNSS positioning more countries have developed a number of standards for geodetic and surveying control, including GNSS equipment working in static or kinematic mode. An example of procedure for checking GNSS RTK equipment it is the ISO (International Organization for Standardization) - "Optical instruments and mechanical - procedures for testing geodetic and terrain of the instruments" - ISO-17123- (1-8), 2012. The ISO 17123 part 8 standard refers to the GNSS RTK measurements and data analysis procedure for verification of such equipment. At present in Romania this procedure it is not yet implemented and a case study was performed at Faculty of Geodesy from Technical University of Civil Engineering Bucharest and the results are presented.
